Abu Dhabi National Oil Company(ADNOC) has been actively

engaging in environmental countermeasures. Gas Conservation Task Force(1996)

Instruct the group companies to eliminate or minimizegas flaring.

Launch a health, safety and environmental managementprogram(1997~)

Reducing the flue gas and wasted materials.

Abu Dhabi Oil Refining Company(TAKREER) Tackle the environmental issues

Making effort to reduce the flare gas

1. Background and Objectives of the Project 1

We conducted joint implementation of

gas recovery project with JCCP

Reduce SO and CO2

the flare gas

The some units emitted a part of the gas to the flare gas header. And they

burn the flare gas in the flare stack.In this project, we executed the introduction of the flare gas recovery unitin the hydrocracker group.And we can recovery the flare gas and reduce the fuel gas.

Remove the H2S

4. Project Overview 4


6/14

We have the following facilities for the flare gas recovery.

This system requires a large land by a Gas holder.

We have a lot of equipment for this system , so the operation is complex.

New Flare gas recovery unit

Introduce the Liquid-Ring compressor and Spill Back Control.a) Stable against fluctuations of flare header.

b) The unit configuration is simple and easy to operation

C) Operating range is wide.( 0 1,000m3N/h)

This project wins The Japan Petroleum Institute s Award for

International cooperation.

This news is also covered the Japanese newspapers.

We not only achieved through this environmental

project, we were able to build a good relationship.

We will continue the good relationship as partners

in the future.
