Title:
METHOD FOR THE CRYOGENIC SEPARATION OF METHANE FROM SYNTHESIS GAS, MORE PARTICULARLY OXOGAS
Document Type and Number:
WIPO Patent Application WO/2014/019697
Kind Code:
A3
Abstract:
The invention concerns a method for separating methane from a synthesis gas flow, particularly an oxogas flow (21), comprising the steps: pre-condensing the synthesis gas flow (21) in such a manner that a methane-depleted gaseous synthesis gas fraction (22) and a methane-enriched CO-rich condensate (23) develop, precipitating the condensate (23), and separating the condensate (23) in a column (35) into a CH4-rich, liquid mass flow (24) and a methane-depleted, CO-rich gaseous mass flow (25), drawing the CO-rich mass flow (25) from the head of the column (35), condensing the CO-rich mass flow (25) and mixing the CO-rich mass flow (25) with the methane-depleted synthesis gas fraction (26).
