The challenge
Aluminum Bahrain (Alba)’s Power Station 5 (PS5) project required the design, engineering, procurement, construction, and commissioning of an 1,800 MW power station in Bahrain. The PS5 power station was designed to host 3 Gas Turbines, 3 Steam Turbines and 3 heat recovery system steam generators, making it the most efficient Power Plant in Bahrain.
GE and GAMA Consortium were responsible for the engineering, procurement, and construction of the power station. Clauger Technofrigo PGE was selected by GE and GAMA Consortium as the supplier of the gas compression systems.
The result
Clauger-Technofrigo PGE designed, executed, supplied, and commissioned four (4) gas compression systems for Alba’s PS5 project. Our gas compression stations included four gas compression systems with related trains and is used for fuel gas boosting to three GE gas turbines. Each gas compression train is comprised of the following primary components:
- Integrally geared centrifugal compressor
- Main Electrical Motor
- Discharge gas cooling system
- Machinery protection system
- Lube-oil system
- Oil-cooler system
- Seal-gas system
- Acoustic enclosure ventilation system
- Air-generating system
- Nitrogen-generating system
- Instrument air-distribution system
