Purge gas in methanol synthesis

摘要

Utilization of hydrocarbon feedstocks in the manufacture of methanol by catalytic conversion of synthesis gas is improved by adding a carbon oxide to a hydrogen-rich purge gas from the process and catalytically converting the carbon oxide-enriched purge gas in a secondary reactor to form additional methanol. The secondary reactor effluent consists essentially of methanol, water and unreacted gases. Methanol is readily separated therefrom.
