Terminal Management for Biofuel Terminals

“Fastest Ethanol Truck Loading in Thailand”

2 Case Study

Increasing demand for biofuel production Thailand’s biofuel producers are reacting to a changing market situation. To cater for the increased demand in biofuel poses a challenge.

Thailand is the sixth largest Ethanol producer in the world. Thai Ethanol industry continues to grow steadily propelled mainly by government policies.

In 2008, the Thai Government increased the proportion of Ethanol in Gasohol to 20% to make E20 and to 85% to make E85. As a result, overall consumption of Ethanol increased. In the next two years the domestic demand for Ethanol in Thailand is expected to increase by an average of 3-5%. This has also to do with expansion of the vehicle fleet being able to use higher ethanol mixes (e.g: E20/E85).

In 2017, the Thai Government launched its plan to build a $11.3B Bio-economy hub for the region.

The rain dependent sugarcane production has paved way for the increase in Ethanol produced from Cassava from 30% to 40%.

Taiping Ethanol Co Ltd is one of the major Ethanol producer in Thailand which uses Cassava roots to manufacture Ethanol.

Production Process Currently Taiping has an installed capacity of producing 150,000 liters per day of Ethanol. Taiping has invested to increase this capacity to eventually 300,000 liters per day.

Cassava flour is liquified to 90-95ºC followed by saccharification at 55-65ºC. It is then cooled down to 30-33ºC. Subsequently this mixture is fermented by adding yeast. During this process the Carbon Dioxide is taken out. This is then finally sent to the distillation unit where Ethanol is produced. Produced Ethanol is mixed with Benzene to produce Gasohol.

Wish list Taiping was looking for an automation system which will help their infrastructure and production process to meet the needs and demands of the industry they serve. Some of the system requirements included:

Previous truck loading skid

Terminal management expertise to optimize your process The right answer for any application in a biofuel terminal.

Loading Metering Skids The redundant loading skid (primary and standby line) incorporates Endress+Hauser Promass F300 Coriolis mass flow meters at its heart. These flow meters are modern yet proven, extremely accurate and with high availability. These meters significantly reduce OPEX and downtime since they do not have any moving part.

The system also addresses the safety /security aspects with card readers and grounding systems on board. The alarm management is configured in the batch controller. For increased safety, a tuning fork type point level switch is attached to the loading arm to prevent overfilling of the compartments.

The card reader validates the driver identity and loading information. The grounding system ensures the truck is grounded before commencing the loading operation and the quality of the Gasohol is maintained using a high precision additive injection system.

The metering system is designed and built in accordance with the recommendations in international standards. The site electrical works and installation was carried out as per the NEC/NFPA guidelines.

Automatic Tank Gauging It is of utmost importance to be in control of your stock. The Endress+Hauser automatic tank gauging system provides safe, accurate and reliable means of performing this task. The system consists of high precision Proservo intelligent tank gauge which is designed for high accuracy custody transfer applications and meets the demands of inventory management and loss control.

It is imperative to have an accurate temperature measurement for custody transfer tank gauging applications. Endress+Hauser Prothermo provides average tank temperature as well as water bottom interface. It’s an intrinsically safe device which allows safest electronic configuration.

Endress+Hauser TankScanner NXA820 and Tankvision forms a robust industrial grade embedded web based Tank Gauging system with high stability and availability.
