<p>Natural gas is reacted with steam, to generate carbon monoxide and hydrogen in a first catalytic reactor ( 16 ); the resulting gas mixture is used to perform Fischer-Tropsch synthesis in a second catalytic reactor ( 26 ). After cooling the resulting gas stream in a heat exchanger ( 29 ), the remaining gas stream ( 30 ) is cooled a second time by decreasing its pressure ( 32 ), and the resulting condensed liquid is separated ( 33 ) from the remaining gas phase. This increases the production of condensate. The second cooling step may utilise a turbine ( 32 ), or a vortex tube ( 40 ), or a throttle valve.</p> |
