PROCESS FOR SYNTHESISING METHANOL

Abstract: a process for synthesizing methanol is described comprising the steps of (i) reforming a hydrocarbon feedstock in a hydrocarbon reforming unit comprising a fired steam reformer to form a synthesis gas containing hydrogen, carbon monoxide and carbon dioxide; (ii) converting the synthesis gas into a methanol product in a methanol loop comprising one or more methanol synthesis reactors; and (iii) recovering a purge gas stream from the methanol loop, wherein at least a portion of the purge gas stream is treated in a purge gas treatment unit by subjecting it to partial oxidation in a partial oxidation reactor or autothermal reforming in a purge gas reforming unit to form a partially-oxidised or reformed purge gas, followed by one or more stages of water gas shift of the partially-oxidised or reformed purge gas in a water-gas shift unit to form a hydrogen-enriched gas and a step of carbon dioxide removal.
