TAQA – Atrush
Gas Liquids Engineering Ltd. (GLE) provided a FEED study for a Gas Sweetening Facility that was planned to be installed at the Atrush oil processing site. The client requested the design package be sufficiently detailed for construction. The Atrush oil processing facility is being designed to be installed over two phases (one train per phase). Each train will be able to process a maximum GOR of 400 scf/bbl and 30,000 bbl/d BOPD producing associated gas volume of 12 MMSCF/d with a H2S composition of 10-20 mol % which will be flared. The Atrush facility relies on diesel fuel for power generation which is very costly. TAQA determined that the incentive to use natural gas to produce power for the Atrush site.
The scope of the project was to design a facility capable of sweetening all of the associated gas to satisfy the fuel gas requirements and potentially have the excess sweet gas available for possible future export.
The design included:
- 2 x 50% electrically driven 3-stage reciprocating compressors with inter-stage cooling at the front end.
- Amine Sweetening Unit utilizing MDEA
- Fuel Gas Conditioning unit
- Gas Turbine Generator
- 40 MMBtu/hr heat medium
- Fuel gas system
- Thermal Oxidizer
- Reverse Osmosis Package
