Abstract
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 th…
