Abstract:
A process for separating hydrogen and carbon monoxide from a condensate-containing gaseous mixture thereof, said process comprising:scrubbing the gaseous mixture, or a vapor portion from phase separation thereof, with a liquid methane wash stream in a methane wash column to provide a gaseous hydrogen product stream and a liquid CO-loaded methane stream;separating said CO-loaded methane stream into a gaseous hydrogen-rich stream and a ""first"" liquid CO/methane stream in a ""first"" stripping column; andseparating said first liquid CO/methane stream into a gaseous carbon monoxide stream and a liquid methane stream in a separation column,whereinfeed gas condensate from the methane wash column or the phase separation is separated into a ""second"" gaseous hydrogen-enriched stream and a ""second"" liquid CO/methane stream in a ""second"" stripping column or a flash separator;the second gaseous hydrogen-enriched stream is fed to the first stripping column; andthe second liquid CO/methane stream is fed to the separation column.
