Indane Gas

• Indane is today one of the largest packed-LPG brands in the world.

• Having launched LPG marketing in the mid-60s, IndianOil has been credited with bringing about a ‘kitchen revolution,’ spreading warmth and cheer in millions of households with the introduction of the clean and efficient cooking fuel.

• Indane network delivers 1.2 million cylinders a day to the doorsteps of over 53 million households, making IndianOil the second largest marketer of LPG globally, after SHV Gas of The Netherlands.

• LPG is a blend of Butane and Propane readily liquefied under moderate pressure.

• LPG vapour is heavier than air; thus it normally settles down in low-lying places.

Supply Chain Management for Indian Oil

1. Planning and Scheduling

2.Supply Chain Planning Solution

3.Supply Chain Scheduling

Solution


As the Indian economy opens, companies are facing increased cost competition. The increase in oil prices has also created the raw material cost pressures in most sectors of the industry. This has made companies look critically at their supply chain and scope of optimization. Advanced planning and scheduling (APS) allows a company to optimize its supply chain as a whole and in parts.

The supply chain challenge for any large multi-site production company can be divided into two major parts - planning and scheduling.

At the planning stage most large corporation have to decide factors related to questions such as: Which feed stock to buy? Where to process? How much to buy readymade and how much to make? What to make and where? How to transport?

Scheduling decisions are related to queries such as: When and in what order feedstock should arrive at manufacturing facility? When and in what sequence or modes to run the equipments? Which orders to meet and what dates to promise?


1.Planning and Scheduling

2.Supply Chain Planning Solution

Demand planning:• For demand forecasting and aggregation of the final demand

numbers based on requirements of supply chain

Integrated Planning:• Planning for the complete supply chain of the customer

based on demand numbers

Distribution Planning: • Generating operational plans for distribution

Production Planning: • Generating operational plans for production.

These modules are supported by various enablers that facilitate planning activity

that include:

• (1) Supply Chain Database (SCD) • (2) Geographical Information System (GIS) • (3)Data Interfaces


The supply chain planning solution, depending on industry segment being considered, can consist of following modules.

3.Supply Chain Scheduling Solution

Based on the planning targets, scheduling solutions optimize the execution of the plan.

This is done using various scheduling tools designed for specific scheduling problem.

Utilize the synergies that exist between these functions to maximize the corporate profit.

Given the large volumes that are involved small percentage changes translate into huge benefits to the owner.

Hardware, Tools Deployment



Indian Oil Corporation Limited (IOCL) has implemented Honeywell’s Supply Chain Management solution to integrate and optimize the supply chain of five separate refineries. The project has resulted in the following benefits:

• Integrated supply chain planning which optimizes the entire supply chain providing higher margins and increased profitability.

• Optimal distribution planning considering transportation costs, taxes and duties and transportation constraints• Improved visibility into its supply chain process across the five selected refineries• Investment analysis for refinery units, pipelines, etc.• Analysis to formulate strategies to meet future scenarios like change in specifications• Faster, more effective decision making on exchange strategies, imports and exports• Improved response and execution capability

Benefits


More visibility into the supply chain and finding ways to optimize this value chain was critical. IOCL evaluated different supply chain management solutions to address this business problem and how best to implement a solution that integrates five separate refineries.• “A multi-site refining company has various supply chain problems to solve including which crude to buy, where

to process it, how much to buy and make, what to make and where and how to transport it, ” said Uttam Kumar Basu, General Manager, Optimization, IOCL.

• Traditionally different departments or divisions within one organization manage their own disparate project of this complex process and don’t always talk with one another. As a result, decisions are sometimes made based on incomplete data or they can’t be applied across the entire corporation.

• To put it in perspective IOCL had challenges in the supply chain to integrate, view and make decisions based on 80 crudes sourced from South America to South East Asia, 10 refineries and five detailed models, along with a large network of 200 depots, 40 terminals, 17 pipelines and six transportation modes. The resulting decision was to implement an integrated, multi-plant planning solution.

Challenge


The Supply Chain Management solution provided by Honeywell consisted of the following modules:

• Demand planning: for demand forecasting and aggregation of the final demand numbers• Integrated planning: for the complete IOCL refining supply chain• Distribution planning: for generating operational plans for feedstock allocation and product

distribution• Refinery production planning: for generating operational plans for production

Solution


Honeywell’s Supply Chain solution effectively helps manage business complexity and optimize the supply chain. With real-time knowledge collaboration and visibility across the enterprise, decisions are made more quickly and disruptions minimized. • Internet-enabled supply chain applications dynamically model the supply chain, and when combined with

advanced execution solutions, substantially improves profitability through measurable inventory and product cost reductions.

• These benefits are realized through faster reaction to market opportunities, improved customer relations, and true collaboration with suppliers and customers.

• Integrated with Honeywell’s advanced applications and the Experion control platform, these products offer an integrated suite of advanced forecasting, planning, and scheduling to manage the supply chain.

Oil Movement & Storage – I(Product Receipt And Blending Section)

This unit is used to:• a) Preparation and supply of feed to unit.• b) Blending of intermediate products.• c) Receipt, storage and dispatch of finished products.• d) Measurement of petroleum products Gauging, sampling etc.• e) Supply of internal fuel oil to Units TPS.GENERAL DISCRIPTION OF THE TANK FARM:

• The tank farm in the receipt and blending section of OM&S consists of different storage tanks for the different intermediate as well as finished products. Some of the important points are:

(A) DIP OR PRODUCT IN A STORAGE TANK:

• It is the height of the oil from the datum plate up to the top oil level.

(B)DATUM PLATE:

• Inside the tank there is a small horizontal plate located approximately 5cms above the tank bottom surface. At the time of taking the dip of oil leveling a tank the bob connected with the dip tape first touches the above plate. This plate is called the datum plate.

(C) TANK PAD :

• It is the developed area with brickwork, concrete and other bituminous material upon which the whole tank shell is resting.

(D) TANK DYKE:

• In is a bound made up of soil surrounding the tank. The purpose of providing dyke is that oil will not spread out in the event to any leakage from the tank shell.


(E) SAFE FILLING HEIGHT:

• It is the height up to which the tank can be filled up safely.

(F) REFERENCE HEIGHT:

• It is the difference in height between the datum plate and the sharp edge in the rectangular groove provided at the top of the dip hatch pipe.

(G)DIP HATCH PIPE:

• It is the cylindrical pipe extending from the bottom of the tank to the top with a cover at the top. Through this pipe only, the dip tape with bob is allowed to enter inside the tank for the purpose of taking dip.

(H)CRITICAL ZONE OF FLOATING ROOF TANK:• Depending on the height of the leg provided with the pontoon roof of floating roof of the tank starts

floating at a certain dip with increase in dip. Between these two dips the pontoon remains slightly in tilting condition. When the dip of any floatation roof tank falls between the above two dips, the dip of the tank is said to be in critical zone.

(I) ROOF DRAIN:

• In floating roof tank, there is a pipe with swivel joint from the center of the pontoon roof. The line extends inside the tank and comes outside the shell from the lower portion of the tank. Rainwater gets out through this drain line.


Oil Movement & Storage – I (contd..)

J) SYPHON DRAIN:

• At the lower portion of the tank shell, one siphon drain nozzle has been provided to get the water drained from the bottom of the tank after being settled.

(K)EMERGENCY ROOF DRAIN:• In a floating roof tank, If there is any leakage in the roof drainpipe inside the tank, it cannot be

operated .In that case the roof drain on the top has to be blinded. An emergency drain has been provided for draining water.

STORAGE TANKS:

• There are three types of storage tanks,

(A) FIXED ROOF TANKS:

• Fixed roof tanks are used for storing low volatile products. These are vertical cylindrical vessel. The fixed roof is provided with internal truss support.

(B) FLOATING ROOF TANKS:• Floating roof tanks are for storing products having high vapor pressure. These tanks have an increased

operation at safety bought about by the absence of vapor space above the liquid as the roof rests on the fluid.

(C) FLOATING CUM FIXED ROOF TANKS:

• These tanks have got the advantages of both fixed and floating roof tanks and are particularly suited to volatile products in which entry of rain water is not permissible.
