Abstract
Integrated process comprising: synthesis of methanol from a methanol synthesis gas (12); synthesis of ammonia from an ammonia make-up gas (25), and synthesis of carbon monoxide from a methane-containing stream, wherein: the synthesis of methanol provides a liquid stream of methanol (13) and a gaseous stream (14) of unreacted synthesis gas; a portion (14a) of said gaseous stream is separated as purge gas; said purge gas is subjected to a hydrogen recovery step, providing a hydrogen-containing stream (19) which is used as a hydrogen source for making the ammonia make-up gas, and a tail gas (20) which is used as a methane source for the synthesis of carbon monoxide by oxidation of a methane-containing stream.
