Okoloma Gas Plant & Pipelines Project

The 240 MMscf/d Okoloma Gas Plant and Pipelines scope of the Afam Integrated Project is intended to supply the base load gas requirement (190 MMscf/d) for the new combined cycle power plant Afam VI (650 MW) and about 50MMscf/d swing supply to the Aluminium Smelting Company of Nigeria (ALSCON) through the existing Nigerian Gas Company (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 comprises the following facilities:


(1) A 120 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

(2) A 120 MMscf/ Twister LTS Low Pressure Gas Processing Train, Condensate Stabilization with Off-gas Compression, Metering, Storage and Export facilities,

(3) The Afam Field Non-associated Gas (NAG) manifold with five incoming 8” flowlines from the Afam wells and one 12” 11 km bulk line from the Afam Field NAG manifold to the Okoloma Gas Plant and

(4) Various other gas and condensate pipelines & flowlines of diameters from 4” to 16” with lengths from 1.2 up to about 12 km,

(5) two transformer stations (33 kV to 6.6 kV) with a distribution to remote consumers and export pumps.
