METHANOL PRODUCTION PROCESS - TECHNOLOGY CONVERGENCE INC

Title:

METHANOL PRODUCTION PROCESS

Document Type and Number:

WIPO Patent Application WO2003029174

Kind Code:

A3

Abstract:

A process for the production of methanol comprises feeding an amount of a hydrocarbon feedstock and an amount of an oxygen feedstock and an optional carbon dioxide feedstock to a partial oxidation reactor and an optional reformer to produce a partial oxidation reactor effluent comprising hydrogen, carbon monoxide and carbon dioxide; electrolyzing water to produce hydrogen and oxygen and recovering at least a portion of the hydrogen to produce a hydrogen stream; adding an amount of a hydrogen feedstock, at least a portion of which is obtained from the hydrogen stream, to the partial oxidation reactor effluent to produce a synthesis gas stream having a predetermined ratio of hydrogen to carbon monoxide and optionally to carbon dioxide; subjecting the synthesis gas to methanol synthesis to produce a methanol product stream and a tail gas stream; separating the tail gas stream into at least two streams comprising a purge stream and a recycle stream, the recycle stream comprising a substantial portion of the tail gas stream; and, recycling the recycle stream to the partial oxidation reactor.
