Abstract

See full text

A process (10) for the recovery of hydrocarbons from a Fischer-Tropsch tail gas includes providing a hydrocarbon rich Fischer-Tropsch tail gas (30) which includes hydrocarbons and carbon dioxide, compressing (14) the hydrocarbon rich Fischer-Tropsch tail gas (30) to provide a compressed hydrocarbon rich Fischer-Tropsch tail gas (36, 54), and contacting the compressed hydrocarbon rich Fischer-Tropsch tail gas (36, 54) with a lean oil (64, 54) to recover the hydrocarbons from the compressed hydrocarbon rich Fischer-Tropsch tail gas (36, 54) and to produce a hydrocarbon rich oil (66). Carbon dioxide is stripped (20) from the hydrocarbon rich oil (66) at a pressure which is below the pressure at which the hydrocarbon rich Fischer-Tropsch tail gas (36, 54) is contacted with the lean oil (64, 54), to provide a stripped hydrocarbon oil product (86).
