ABSTRACT:
An integrated large capacity, single-train process for making 1,00020,000 MTPD methanol and 3006,000 MTPD acetic acid is disclosed. Syngas120is produced by autothermal reforming118of natural gas102where the feed112of the natural gas is supplied with oxygen and CO2 recycle110to the autothermal reformer (ATR)118. A portion (5-50%) of the syngas is fed to CO2 removal122to obtain the recycle CO2 and cold box130to obtain a hydrogen stream131and a CO stream135. The 50-95% remaining syngas, hydrogen stream131and optionally any CO2 from an associated process are fed to methanol synthesis140, which produces the methanol. The methanol is supplied to an acetic acid unit136with the CO135to make the acetic acid, which in turn can be supplied to a VAM synthesis unit148. Oxygen for the ATR and any VAM synthesis can be supplied by a single common air separation unit116, and utilities such as steam generation can further integrate the process.
