Abstract: A Fischer-Tropsch-based process and system for converting light hydrocarbons into heavier hydrocarbons uses a plurality of different synthesis gas generators. The process includes preparing a first synthesis gas having a H2:CO ratio greater than 2:1; removing a portion of the hydrogen from the first synthesis gas; preparing a second synthesis gas with a CO2 recycle wherein the second synthesis gas has a H2:CO ratio less than 2:1; adding the removed hydrogen to the second synthesis gas to increase the H2:CO ratio of the second synthesis gas; and using a Fischer-Tropsch reaction to convert the first synthesis gas and the second synthesis gas to heavier hydrocarbons.

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.
