Companions Tour

Annual Conference, Istanbul, September 2016 In 2016, for the first time, GPA Europe will combine its Annual Conference with their colleagues in the GPA’s Gulf Co-operation Council (GCC) Chapter. We believe that there is a real synergy to be gained from networking between the predominantly Supplier-based European Chapter and the Producer-dominated GCC Chapters. The meeting has been organised jointly, with presentation offerings from both Chapters to provide an unequalled opportunity to share views and experiences and to make new contacts and to network with your peers.

Technical Meeting

There has been overwhelming interest in presenting at this conference and, as a consequence, the meeting will start on the afternoon of Wednesday, 21 September. The registration desk will be open from 1300 on 21st September where delegates will be able to collect name badges and conference materials including a pack of all papers in electronic format.

The formal opening of the meeting will be on Thursday 22 September at 0900 with welcome presentations from the Chairmen of both Chapters and a Keynote Speech from a Representative of the Turkish Chamber of Petroleum Engineers on Natural Gas in Turkey.

The conference has been divided into 4 sessions offering a total of 20 high quality technical presentations. Full detail on the papers being presented is detailed below.

The conference will close at 12 noon on Friday 23 September.

Welcome Reception

Kindly sponsored by ABB Consulting and IMA, the traditional Welcome Reception will take place at 1800hrs on 21st September in either the Remina Garden or the Baykoz Room, depending on the weather. This will provide an excellent opportunity to meet other delegates and renew old friendships.

Conference Dinner

Courtesy of the generosity of PECO Facet and CECA, the Conference Dinner will be a Dinner cruise on the Semiramis, on the Bosphorus. This is a great opportunity to see Istanbul by night from the sea and, during the dinner, there will also be entertainment to make the evening most enjoyable and memorable.

Companion’s Tour

As is traditional for GPA Europe Annual Conferences, we will make a relaxing Companions Tour available for the spouses/companions of delegates on 22 September. This year the tour will take a boat trip to the serene Princess Islands in the Sea of Marmara and specifically to Buyukada. Here, where Turks take holidays from the bustle of Istanbul, there are no cars, and we have organised a trip around the island by horse carriage, to see beautiful Victorian era villas and St George’s Church at the summit of the island. Lunch will be taken at a seaside Fish Restaurant, before the voyage back to Kalamis.

Security

Like many cities around the world, Istanbul is no stranger to the dangers of modern life. In organising this meeting, GPA Europe has been very mindful of this fact. The hotel has been specifically selected as being away from the centre of Istanbul, but yet sufficiently accessible for those individuals who wish to visit the tourist sites. The excursions for the Companions Tour and the Conference Dinner will both start and finish within 500 metres of the hotel in Kalamis Marina and, unless individual delegates wish to do so, there is no intention of moving into major tourist locations.

The hotel is easily accessible from both Ataturk and Sabhia Gockem airports and taxi transportation from organized taxi ranks at the airport is no more risky than any other European airport. Traffic is however notoriously bad in Istanbul and plenty of time should be allowed, particularly at rush hour, to get to and from the airport.

While a continuing watch on local developments will be maintained, GPA Europe is confident that the conference will be a great success and valuable for all delegates.

Young Professionals Initiative

GPA Europe, in pursuit of opening up knowledge of the Gas Processing industry to younger engineers, is offering its usual discount for the main Conference. Young Professionals (those within 5 years of graduation) are invited to attend with a more senior colleague at a discount of £ 200 (€ 250) off the senior colleague’s package cost. Further details on this package can be found within these details. We encourage members to use this attractive discount to offer training and exposure to the industry to the benefit of the future of global gas processing.

Sponsorship

In addition to the companies already mentioned, GPA Europe would like to express their sincere thanks to Kelvion, BASF, Eastman, Fluor and Tranter for their very generous sponsorship of the Conference. These companies will be present with small exhibit stands during the meeting.

Wyndham Kalamis Grand Hotel

The Wyndham Kalamis is a modern hotel situated on the Asia-side of the Bosphorus in a stylish part of Istanbul. The Marina after which the hotel takes its name contains large yachts providing an impressive view. A number of excellent restaurants are available in very close proximity to the hotel.

Bagdat Street, one of the key shopping districts of Istanbul is within 200 meters of the hotel, and the ground of Fenerbahce Football Club is also close by.

Sales Gas Storage in Saudi Arabia

Mohammed B. Bu Hassan, Rashid Al-Othman, Yuguo Wang, & Cemal Ercan, Research & Development Center, Saudi Aramco

This paper discusses the work done by Saudi Aramco Research & Development Center (SA R&D Center) for the demonstration of an-adsorption-based process for storing sales gas in the Kingdom of Saudi Arabia. The discussion will include the description of a case study to build a storage facility, which will be located near a power generation plant so that sales gas can be withdrawn from it during high-demand hours of the summer season to meet load variations.

This paper will discuss the isotherms, breakthrough curves, adsorption kinetics, diffusion coefficients, heat of adsorption, which were determined as integral part of R&D activities for the development of the processes. Additionally, the pseudo-steady state cyclic behavior of the multiple adsorption/desorption cycles, heating/cooling effects, modeling and model validation will be discussed with the experimental data.

As background data, the history of sales gas production in the Kingdom as well as the different options for sales gas storage will also be included.

Use of CFD Modeling to Optimize Capital and Operational Costs of Molecular Sieve Units

Sandeep Jain & Assaad Ghusoub, CECA SA and Thomas Boucheres & Leonel Gomes, ARKEMA

A major challenge for industrial operators and EPC firms is to optimize capital and operational costs of their new and existing facilities. Computational Fluid Dynamics (CFD), even though a powerful and comprehensive modeling tool, is not widely used in molecular sieve industry. This paper will focus on CFD models developed by CECA (Arkema) and their applications to optimize the adsorption and regeneration phases. The first part will discuss ways to optimize the molecular sieve bed designs through insight on bed configuration, hydrodynamics and other process parameters. The second part will address the troubleshooting issues, optimizing and adapting the plant operation under different constraints. The two parts, that are key to cost savings, will be illustrated using real industrial cases.

Heat Recovery from Hot Wet Regeneration Gas in Dehydration Unit - Badak LNG

Zaki Arif, Technical Department, Badak LNG

Adsorption dehydration is used for most applications where removal of water moisture in natural gas is required to meet LNG specification. In Badak LNG the dehydration unit consists of 3 vessels filled with molecular sieve and alumina which is operated with a sequential logic in such a way that at any time 2 vessels are in service cycle while the other one is in regeneration cycle.

Regeneration of saturated dehydration bed is a critical operation. It is performed by taking small portion of dried gas exiting the dehydration unit heating up by using high pressure steam and then passing it through the saturated bed to drive off absorbed water. In the original design after regenerating the bed the hot wet gas then is cooled before recycling it to the process upstream.

In order to recover the heat from the hot wet gas modification was made in the dehydration unit by adding a heat exchanger utilized as regeneration gas pre-heater. In the new pre-heater the hot wet gas exiting dehydration bed is contacted with the cold regeneration gas entering the bed. This new configuration has been proven to reduce high pressure steam consumption for regeneration process by approximately 40% or equivalent to a cost saving of $ 260,000/year.

Energy Efficiency Improvement Opportunities by CHP Systems

Ahmad A. Zaki, Saudi Aramco (Hawiyah)

Combined heat and power (CHP) integrates the production of usable heat and power (electricity), in one single, highly efficient process. CHP generates electricity whilst also capturing usable heat that is produced in this process. This contrasts with conventional ways of generating electricity where vast amounts of heat is simply wasted. In today’s combustion gas turbines, up to two thirds of the overall energy consumed is lost in this way, often seen as a cloud of steam rising from exhaust stacks.

By using waste heat, CHP plants can reach efficiency ratings in excess of 80%. This compares with the efficiency which normally ranges between 49% and 52%.

The Hawiyah Natural Gas Liquids (NGL) Plant comprises amongst others 4GE frame 7 gas turbines (unit A, B, C, and D – 4 x 25%) driving sales gas compressors. They are part of a CHP plant, each equipped with a Heat Recovery System consisting of a MP Hot Water (425°F, 400 psig / 218°C, 28 barg) and a LP Hot Water (340°F, 190 psig / 171°C, 13 barg) system. The LP hot water system is used by several consumers in the NGL plant. The MP Hot Water system is mainly used to heat up regeneration gas from 140°F (60°C) to 400°F (204°C). This regeneration gas is then further heated up to 550°F (288°C) in electrical heaters.

The electrical heaters have a negative impact on the reliability and availability of the overall NGL plant by premature failures, resulting in higher maintenance cost, higher down time, increased safety concerns which triggered essential modifications to the system to improve overall reliability and availability.

At the same time the Hawiyah NGL energy study has identified energy efficiency improvement opportunities related to the above system. The plant is currently operating with three HRUs at part load (controlled by flue gas louvre dampers) and one bypassed with the bypass stack. As four HRUs are installed, though only two to three units of partial loads are required for the heat demand of the hot water systems, this left significant potential for energy efficiency improvements.

Based on a dual pressure steam HRSG configuration combined with a steam turbine. The proposed steam turbine generates electricity using the steam which is not required for heating the regeneration gas and thus recovers energy from the 50% of the exhaust heat which is currently lost. The high temperature regeneration gas heating is achieved by using HP steam. Steam is also bled from the turbine to provide heat to MP and LP hot water systems and then generates 85 MW electricity comprising 97 MM$ revenue per year.

How to Design Safe Processes – Learning from Others’ Mistakes

Chris Flower, ABB Ltd

Errors are inevitably made within the design process and some of these can lead to unsafe process and plants. Oil and Gas companies have been introducing 3rd party process safety reviews in order to identify and eliminate these before final design and construction. The findings from twenty two such gas processing projects were reviewed in order to identify common themes and pitfalls. These were broken down into three categories: procedural; managerial; and behavioural. This paper will describe the findings from this review and will share recommendations on how to improve the Contractor / Operator Project Management Team relationships and procedures in order to provide safer process designs.

KEYNOTE SPEECH - Strategic Role of Turkey in the Regional and Global Natural Gas Markets

Ahmet Necdet Pamir, Chairman Energy Commission, Turkish Republican People's Party

With its vibrant economy and rapidly increasing energy demand Turkey is both a growing market and a vital transit hub both for oil and natural gas supplies between rich hydrocarbon sources of the Middle East the Caspian Russia Africa Mediterranean and the demanding markets of the EU and other Atlantic markets.

32 percent of its energy demand is supplied by natural gas while the country is almost totally dependent to imports most of it being from Russia. The critical concept of energy security problems and the need for diversification is well practised in this country. Therefore Turkey is both a case in point to analyse and also is excellently located to serve for Europe’s diversification needs. New projects like TANAP as well as potential pipeline and LNG alternatives from Eastern Mediterranean Iraq Iran and Central Asia will not only help to increase Turkey’s energy security but will also serve for similar concerns of the EU.

Subsea processing is proven - What's next?

Marco Davide Gabelloni, Regional Concept Line Manager for Advanced Subsea Production Aker Solutions

The successful project completion commissioning and now ongoing operation of Asgard subsea processing and compression system have shown how this technology can be utilized as a robust and viable solution for maximized hydrocarbon recovery. For Aker Solutions and its partners in this endeavour the Asgard project represents decades of ongoing developments in subsea compression technologies and have provided many learning opportunities for further optimization and simplification of such systems. This experience is particularly relevant in the current oil and gas industry scenario with operators looking for cost effective solutions based on qualified core technologies. This presentation will focus on Aker Solutions portfolio of subsea compression systems starting from the background of subsea processing and the specific benefits of subsea compression in terms of higher recovery and reduction in the total cost of ownership. The details of Agard system will be presented including main process and power distribution components together with installation and maintenance considerations and an update on the system performance. Finally future developments and possibilities for the system based on the lessons learnt from Asgard project and a close cooperation across the supply-chain will be discussed.

Value Added in Integration of Three Cryogenics Processes: NGL NRU And HRU

Ludovic Granados, Marie-Pascal Victor Michele, and Pierre Costa de Beauregard, Air Liquide

Cryogenic natural gas processing plants sometimes include:

• Natural Gas Liquids extraction

• Nitrogen Rejection

• Optionally: Helium recovery

These three processes have been implemented at many locations worldwide. This paper will introduce the three independent processes and will show how their integration can bring value to customer. An innovative integration will be presented illustrated with the example of a recent FEED study of a multi-train gas processing plant performed by Air Liquide. Benefits are energy savings and reduced capital expenditure through optimized multi-train strategy. Optimization of reliability and availability critical for such multi-train projects will also be introduced.

Novel Ejector Refrigeration Cycle for NGL Recovery Plant

Omar M Baageel, Berri Gas Plant, Saudi Aramco

Typical NGL Plant compresses its feed to a high pressure, which also increases the feed gas temperature. After that, the feed gas is cooled by a huge air fin-fan cooler followed by three-stage propane refrigeration cycle. Such designs are widely used in NGL Recovery Plant worldwide. Feed gas temperatures after compression can reach up to 150OC. One possible use for such waste heat is to generate cooling using a heat-operated refrigeration system such as ejector refrigeration cycles. This novel multistage ejector refrigeration cycle, which are based on 45OC ambient temperature, are operated by the waste heat at the feed gas compressors discharge. It is designed to provide cooling to the feed gas which will reduce the load on the refrigeration compressors significantly. The novel cycle has a COP of 0.714 which is competitive with the compression refrigeration COP of 0.80. It can replace the third refrigeration compression stage and provide 105% of its’ cooling capacity, thereby, meeting the deign goal. For a typical 2,700 m3/hr NGL Recovery plant, the new design saves $12 Million in capital costs and $1.5 Million in annual electricity cost. In addition, this cycle is environmental friendly which reduces CO2 emissions by 47,000 metric tons per year.

The Accidental Abatement of Black Powder in North American Pipelines

David Burns. PECO Facet

Black power is a mixture of pipeline corrosion reaction compounds such as iron sulfide iron oxide and iron carbonates. Black power has been a nuisance ever since iron pipelines have been used to transport natural gas from production fields to point of use customers. Every natural gas pipeline in the world has some level of black powder contamination.

GCC natural gas producers have been forced to install large filtration and separation plants to handle very high concentrations of black powder prior to point of use custody transfer locations. These large plants are expensive to purchase and install and very expensive to operate. An interesting observation is that these large black powder filtration and separation plants seem to only be deployed in GCC operating countries. GCC natural gas is largely the same as natural gas found all over the world. Pipeline materials are also basically the same. Why do GCC pipelines have larger concentrations of black powder than in other natural gas producing regions?

Black powder became a noticeable problem for North American pipelines in the 1950's when the need to push gas down the pipeline was addressed with some of the very first natural gas compressors. Today black powder still exists and is found from production and gathering systems all of the way down to point-of-use customers. Yet large black powder filtration and separation plants are not used in North America. The intent of this study is not to solve the “Black Powder” problem, but to simply compare pipeline and process operational differences between North American and GCC pipelines. Results obtained suggest that the North American abatement of large black powder issues may have been accidental.

Energy Optimization of CO2-Removal Amine Process by Increasing Stripper Pressure

Ali K. Al Hemaid, Hawiyah Gas Plant, Saudi Aramco.

Saudi Aramco Hawiyah Gas Plant has successfully achieved an 11% reduction in amine regeneration energy requirements for an Acid Gas Removal Unit equivalent to 1$MM annually by slightly increasing stripper pressure by 4 psi. This is contrary to the common wisdom of operating amine strippers in as low pressure as possible which is thought to aid stripping by lowering the partial pressure of acid gas. As shown in actual field testing, the higher pressure has actually improved stripping by combination of factors, including reducing the ratio of H2O to CO2 equilibrium partial pressures, and reducing latent heat of stripping steam.

Why Amine Systems Fail - Gas Processing Focus

Philip Le Grange, Mike Sheilan, and Ben Spooner, Sulphur Experts Inc.

Equipment malfunction or unplanned shutdown of an amine system can have a devastating effect on a production company's profitability. The goal of this paper is to determine and focus the Gas Processing Industry's attention on the highest probability threats to their facilities reliability. The threats were identified by analyzing 400 cases of amine system failure investigated by Amine Experts over the last 17 years for the root causes of the corrosion foaming hydraulic restrictions and specification problems that have limited or crippled gas processing facilities the world over. The most prevalent causes of failure in amine systems both in general and in gas processing specifically are determined and strategies to prevent these are given.

World's First Modular Seal-Less Compressor for Corrosive Gas Applications

Eyad M. Al Khateeb and Ibrahim S. BuBshait, Saudi Aramco & M.P. Buse and M. van Aarsen, Siemens

Hermetically sealed integrated high-speed motor-compressors offer considerable advantages to gas processing applications. Examples of benefits to gas processors include wide operating flexibility 80% reduction in instrumentation over 50% reduction in installed space and for modular design easy fitting/commissioning & relocation. Some designs can even handle wet or dirty gases. When hermetically sealed designs eliminate Dry Gas Seals and lubricated bearings along with their supporting auxiliary systems their operational reliability & safety are boosted from the elimination of the highest source of unscheduled shutdowns. However this means that the entire integrated motor- compressor rotor and magnetic bearings would be exposed to the compressed process gas. This has been done before and is not a challenge for sweet non-corrosive processed gases. When the challenge to the Saudi Aramco team was to provide a modular minimum-utility easily relocatable compression solution that can handle corrosive gases with a very wide variation in gas Molecular Weight flow and pressure it was obvious that the hermetically sealed design needs to be advanced and extended to handle sour gases. The outcome was the World's 1 St Modular Seal-Less Compressor designed for Wet Corrosive Gas Applications. This is arguably the most advanced compressor installed and running in the world. Several major challenges were overcome including the suitability of all wetted components to sour and corrosive gases special design of magnetic bearings cooling process gas and vulnerability of the electrical insulation system. This paper discusses how proven designs were taken through a leap to the next step in compressor development that can handle any gas application. Components were subjected to a series of compatibility tests and the entire package then was put through an extensive test program including emergency landings on the auxiliary bearing system and full- pressure full-load testing to ASME PlC-b 0 Type-1 testing standards at the OEM's facility in Hengelo The Netherlands. Upon successful completion of testing the unit was shipped and commissioned at the site gas compression facilities in Saudi Arabia and started operation in June of 2015. The paper covers the design concept of the 'canned' hermetically sealed technology and how it was advanced to dynamically handle a wet corrosive gas application with huge variations in Molecular Weight (from 26 to 44) and a varying 2000-12000 m3/hr flow range.

VOC Recovery in Onshore and Offshore Marine Loading of Crude Oil

Wil Lee, Mike Dodd, and Grant Johnson Costain

Vapour emissions during loading of crude oil contain volatile organic compounds (VOCs) which react in the atmosphere to form ozone a cause of smog and include components such as benzene all of which can be harmful to health.

Facilities to reduce VOC emissions during loading of ships are providing major environmental benefits in Europe and North America their installation being driven by emissions standards and legislation. Ability to recover VOCs into the crude oil or to produce a liquid fuel to generate power also provides an economic benefit and the sensitivity of the economics to the value of oil potentially impacts technology selection. Viable technical options are discussed with reference to a large VOC recovery installation at a European oil loading terminal.

Reduction in VOC emissions from onshore loading jetties is well understood. Nearshore loading of oil from single point mooring (SPM) buoys and other offshore structures is however also common. The associated vapour emissions can still impact local populations and the specific challenges and potential solutions to reducing emissions in these facilities are also described.

Reducing Emissions through CO2 Capture & Compression

Abdullatef A. Al-Mufti, Hawiyah NGL Plant, Saudi Aramco

The CO2 Capture and Compression Unit is part of the Saudi Aramco Carbon Management programs that is developed to introduce carbon management technological solutions that will reduce greenhouse gas emissions and at the same time maintain oil position as a major contributor to the global energy market. This unit will result in reducing CO2 emissions in Hawiyah NGL Plant by capturing 0.8 million tons per year. The unit will receive approximately 40 MMSCFD of wet CO2 from two DGA (diglycolamine) trains which sweetens gas from Haradh Gas Plant prior to NGL recovery. This gas will be dried and compressed utilizing:

• An integrally-geared compressor to compress the CO2 up to 1600 psig.

• A Tri-Ethylene Glycol (TEG) dehydration unit located between stages of the integrally-geared compressor to dry the CO2.

• Inter-stage cooling will be accomplished with cooling water

• The final compression stage will be a dense phase pump which will increase the dry CO2 pressure up to 3500 psig to maintain the required minimum arrival pressure of 2800 psig at the delivery point.

Carbon dioxide utilized for enhanced product recovery from a natural gas field

Angels Nolis Verges Jurgi Geurtz Fluor Netherlands B.V. and Nick Amott Fluor Ltd UK

In the effort to tackle green house gas emissions to the atmosphere carbon capture can definitely make an important contribution. However the main challenge faced by the carbon capture technologies is the actual carbon dioxide utilization.

In some depleted oil fields carbon dioxide is currently used for enhanced oil recovery. The oil is separated from the CO2 and the CO2 is re-injected into the oilfield. In natural gas processing carbon dioxide is separated from sour natural gas (gas that contains H2S and/ or CO2) and the separated CO2 and H2S mixture (acid gas) is then stored in empty gas fields.

For a client in Western Europe Fluor is investigating enhanced hydrocarbon recovery for a partially depleted gas-condensate field using CO2 injection. While the client's aim is to permanently store CO2 it wants to investigate whether hydrocarbons could still be recovered after CO2 injection commences. The carbon dioxide to be injected into the field will be captured from an existing power plant in the vicinity of the gas field. Fluor is looking into re-using the existing natural gas liquid (NGL) recovery facility to continue production after CO2 injection has commenced and to subsequently separate CO2 from the produced condensates and possibly also the natural gas itself. The CO2 will then be re-injected back into the field and re-circulated until the operational costs of the process are higher than the value of the products that can be recovered after which the CO2 will be finally stored in the field.

This paper presents the results of Fluor studies regarding re-using the existing NGL facility to separate CO2 from the natural gas and associated liquid products. The results presented show:

• The product recoveries that can realistically be achieved from the gas (rich in CO2) using the existing NGL facility as it is today

• Possible optimizations (design options) of the existing facility to improve the product recoveries

• Technological solutions to recover the complete range of products

• The economical evaluation of each design option.

Enhanced Control Techniques for Cryogenic Turboexpander/Recompressors

Medhat Zaghloul, Compressor Control Corp

Antisurge control of a compressor in the turboexpansion train is often ignored. This approach may result in damage to the train and loss of valuable production. Traditional control system for this type of machines is primarily designed to protect individual units from working beyond the operating envelope. However control strategy used in various parts of a plant can be used not only for the protection of machinery but also to maximize the production capacity of a gas processing plant. The aim of this article is to underline the features that are essential for achieving good results from this rotating equipment and present the enhanced Control Techniques for Cryogenic Turboexpander /Recompressors to achieve safe and accurate operations while maximizing the production. The article also discusses the association of turboexpanders with recompressors in parallel turbomachinery trains with their piping configuration and control challenges.

Successful Journey in flaring reduction

Asyad Al Saleh, Ju’aymah NGL Fractionation Plant, Saudi Aramco

Ju'aymah NGL Fractionation plant (JNGLF), the primary source of NGL feed to petrochemical industries in the eastern part of Saudi Arabia, has successfully achieved more than 70% reduction in its flared gas volume . This major reduction was experienced after 18 months from commencing its journey of focused Flare Minimization Plan [FMP] while maintaining plant's position as a 1.1 million barrel-per-day-capacity of NGL and with no capital investment for Flare Gas Recovery installation.

FMPs are structured programs in line with achieving and sustaining the operational excellence as part of Saudi Aramco strategies in environmental performance and energy efficiency. The key success behind JNGLF story was investing its resources around four (4) key dimensions for reducing flaring: control valves leakage, flow meters reliability, flare monitoring and control and purge gas optimization. Maximum leakage as per control valves classification was routinely tested and a better performance was observed after implementing required maintenance. Flow meters calibration was advanced as a result of collaborative site verification with meters’ manufacturer technicians. Daily monitoring and reporting has promoted awareness on operational changes to reduce flaring and new ideas were successfully implemented. Purge gas requirements have also been thoroughly studied and optimized while ensuring it fully meets its design objectives.

The presentation would also address the identified challenges in JNGLF with the path forward to sustain its performance and further reduce environmental emissions. These ongoing efforts have materialized into a cultural transformation on flaring reduction and significantly enhanced the interaction with operation workforce.

Design challenges for a zero flaring concept

Stéphanie Druesne - Technip

Flares play a critical role as a safety device in oil and gas processing facilities during plant emergencies upsets normal operating conditions and start-up. But the increased environmental concern and tightening regulations affect more and more their design in such a way that environmental pollution is reduced as much as possible. Recently TECHNIP has experienced multiple engineering challenges to limit any atmospheric discharge from any source by almost eliminating gas flaring within a "zero flaring" concept. Different process schemes have been developed to cope with the specific constraints on the projects. This paper describes the possible design options and evaluates the benefits and drawbacks of each process scheme. The technical discussion covers the main design features of a closed flare system such as the technology of the flare gas recovery unit the type of device to isolate the flare system and the flare gas ignition method.
