TAQA – Atrush Gas Sweetening Facilities

Gas Liquids Engineering Ltd. (GLE) provided a FEED study for the Atrush Gas Sweetening Facilities. The facility currently relies on diesel fuel for power generation, which is very costly. The client wishes to switch to natural gas for power generation, but the Atrush fluids are very sour (contain 10 to 20 mol% H2S). The scope of the project is:

  • Design and install a facility capable of treating all associated gas from the Atrush production facilities to satisfy the fuel gas requirements and potentially have excess sweet gas available for possible future export.
  • The oil processing facility is 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 bopd, a solution gas volume of 12 MMSCF/d.
  • Gas compression at the front of of the process. 2 x 50% electronically driven 3 stage reciprocating compressors with inter-stage cooling
  • Installation of a 3rd Gas Turbine Generator (GTG)
  • Amine Gas Sweetening System utilizing MDEA
  • Gas Filtration
  • Installation of a 40 MMBTU/hr Heat Medium
