Project Characteristics

The 240MMscf/d Okoloma Gas Plant and Pipelines scope of the Afam Integrated Project has been initiated to supply the base load gas requirement (190MMscf/d) of the new combined cycle power plant, Afam VI (650 MW) and about 50MMscf/d swing supply to the Aluminum Smelting Company of Nigeria (ALSCON) through the existing NGC manifold and pipeline.
The Afam VI Power Plant supplies about 20 % of Nigeria’s 2009 operational power generation capacity.
The fast track Okoloma Gas Plant & Pipelines Project comprise the following facilities:

  • A 240 MMscf/d JT-LTS (Joule Thomson-Low Temperature Separation) High Pressure Gas Processing Train, with a 33 kV distribution and transmission network and 33 kV switchboards
  • A 120 MMscf/d Twister-LTS Low Pressure Gas Processing Train,
  • Condensate stabilization with off-gas compression, metering, storage and export facilities,
  • The Afam Field NAG Manifold with five incoming 8’’ flowlines from the Afam wells and one 12” 11 km bulkline from the Afam Field NAG Manifold to the Okoloma Gas Plant and
  • Various other gas and condensate pipelines & flowlines of diameters from 4” to 16“ with lengths from 1.2 up to about 12 km
  • Two transformer stations (33 kV to 6.6 kV) with a distribution to remote consumers and export pumps.
