A system for converting lighter hydrocarbons to heavier hydrocarbons has a synthesis gas subsystem for receiving air and light hydrocarbons and producing a synthesis gas; a synthesis subsystem for receiving synthesis gas from the synthesis gas subsystem and producing heavier hydrocarbons therefrom and an aqueous byproduct stream having contaminates; and a stripper subsystem for receiving the aqueous byproduct stream and removing contaminates therefrom, wherein the stripper subsystem includes a concentrator column for concentrating contaminates in an aqueous by product stream, and a stripper column for stripping contaminates from a concentrated aqueous byproduct stream. A method for producing heavier hydrocarbons from lighter hydrocarbons includes the steps of: reacting air and a light hydrocarbon feedstock to produce a synthesis gas; delivering the synthesis gas to a Fischer-Tropsch reactor; using a Fischer-Tropsch reaction in the Fischer-Tropsch reactor to convert the synthesis gas into heavier hydrocarbons; removing contaminates from an aqueous byproduct stream; and wherein the step of removing contaminates from the aqueous byproduct stream includes the steps of: concentrating the contaminates in a concentrator column, and using the light hydrocarbons in a stripper column remove the contaminates from the byproduct stream.

[ What is claimed is:] [1.]1. A method for producing heavier hydrocarbons from lighter hydrocarbons, the method comprising the steps of:reacting an oxygen-containing gas and a light hydrocarbon feedstock to produce a synthesis gas;delivering the synthesis gas to a Fischer-Tropsch reactor;converting the synthesis gas into an effluent containing heavier hydrocarbons;separating an aqueous byproduct stream from the effluent;removing contaminates from the aqueous byproduct stream; andwherein the step of removing contaminates from the aqueous byproduct stream comprises the steps of:concentrating the contaminates in a concentrator column to produce a concentrated contaminate effluent,condensing the concentrated contaminate effluent to form a concentrated condensate stream,accumulating the concentrated condensate stream in a reflux drum, andusing a stripping gas in a stripper column to remove the contaminates from at least a portion of the concentrated condensate stream to produce a treated water stream and a stream containing contaminates and the stripping gas.
