<p>Natural gas is processed to generate longer-chain hydrocarbons, the process comprising subjecting the gas to steam reforming to generate a mixture of carbon monoxide and hydrogen, and then subjecting this mixture to Fischer-Tropsch synthesis. The reforming reaction ( 20 ) is performed at 0.4-0.5 MPa and the Fischer-Tropsch synthesis ( 50 ) at 1.8-2.1 MPa, and two compressors ( 36, 44 ) are used to raise the pressure, the gas mixture being cooled ( 26, 32, 40 ) before and after the first compressor ( 36 ). This reduces both the operating cost and capital cost of the plant.</p> |
