Abstract
A process for recovering light Fischer-Tropsch hydrocarbons from a rich tail gas produced from a Fischer-Tropsch synthesis operation which comprises: (a) recovering separately from a Fischer-Tropsch synthesis operation a Fischer-Tropsch condensate and a hydrocarbon rich Fischer-Tropsch tail gas; (b) cooling the Fischer-Tropsch condensate and Fischer-Tropsch tail gas; (c) using the cooled Fischer-Tropsch condensate as a lean oil to adsorb at least a portion of the light Fischer-Tropsch hydrocarbons present in the Fischer-Tropsch tail gas, whereby a rich oil mixture comprising Fischer-Tropsch condensate and light Fischer-Tropsch hydrocarbons is formed; and (d) collecting the rich oil mixture.
