PRODUCTION PROCESS OF STREAM, ENRICHED BY HYDROGEN, AND STREAM, ENRICHED BY CARBON MONOXIDE, THE TRANSFORMATION PROCESS OF PRIMARY METHANOL INSTALLATION TO THE INSTALLATION FOR THE SYNTHESIS OF ACETIC ACID AND THE PRODUCTION PROCESS OF HYDROGEN AND ACETIC ACID FROM METHANOL

摘要

A method for the production of syngas from methanol feedstock is disclosed. The methanol feed (110) is supplied to a partial oxidation reactor (112) with oxygen (114) and optionally steam (116) to yield a mixed stream (118) of hydrogen, carbon monoxide, and carbon dioxide. The carbon dioxide (122) is separated out and the hydrogen and carbon monoxide mixture (124) is fed lo a cold box (126) where it is separated into hydrogen-rich and carbon monoxide-rich streams (130, 128). The separated carbon dioxide (122) can be recycled back to the partial oxidation reactor (112) as a temperature moderator if desired. The carbon monoxide-rich stream (128) can be reacted with methanol (134) in an acetic acid synthesis unit (132) by a conventional process to produce acetic acid (136) or an acetic acid precursor. Optionally, an ammonia synthesis unit (144) and/or vinyl acetate monomer synthesis unit (156) can be integrated into the plant.
