GENERATION OF ELEVATED PRESSURE GAS MIXTURES BY ABSORPTION AND STRIPPING

摘要

A method of making a reaction product comprising (a) generating a crude synthesis gas containing hydrogen, carbon monoxide, and carbon dioxide in a synthesis gas generation system by converting a first portion of a natural g as feed therein; (b) introducing the synthesis gas into a reaction system and converting the synthesis gas into the reaction product and unreacted synthesis gas comprisi ng carbon dioxide; (c) absorbing a portion of the carbon dioxide in the unreact ed synthesis gas in a lean absorber liquid in an absorber column to provide a rich absorber liquid; (d) transferring the rich absorber liquid to a stripping column; (e) stripping the rich absorber liquid in the stripping column with a second portion of the natural gas feed to provide a stripped absorber liquid and a stripping column overhead gas comprising carbon dioxide and methane; (f) recycling the stripping column overhead gas to the synthesis gas generation system; and (g) recyclin g the stripped absorber liquid to the absorber column to provide the lean absorber liquid in (c).
