Methanol production system that efficiently recycles unreacted gas through intermediate cooling discharge function and hydrogen recovery

Abstract

A methanol production system capable of improving methanol production efficiency is provided. The methanol production system includes a waste gas reformer configured to reform a waste gas comprising a hydrocarbon (CxHy) gas and carbon dioxide to generate a synthesis gas containing hydrogen, carbon monoxide, and carbon dioxide; a methanol production reactor including a first reaction zone containing a first catalyst, the first reaction zone configured to receive the synthesis gas and facilitate a reaction of the synthesis gas to generate methanol, and a second reaction zone containing a second catalyst, the second reaction zone configured to receive unreacted gas from the first reaction zone and facilitate a reaction of the unreacted gas to generate methanol; a first condenser configured to condense and separate methanol and water from gas discharged from the methanol production reactor; and a gas separator configured to separate a recycle gas comprising hydrogen, or a mixture of hydrogen and carbon monoxide, from gas discharged from the first condenser.
