Abstract
An integrated process for making methanol, acetic acid, and a product from an associated process is disclosed. Syngas () is produced by combined steam reforming () and autothermal reforming () of natural gas () where a portion () of the natural gas bypasses the steam reformer () and is blended with the steam reformer effluent for supply to the autothermal reformer (ATR) () with CO2 recycle (). A portion of the syngas is fed to CO2 removal () to obtain the recycle CO2 and cold box () to obtain a hydrogen stream () and a CO stream (). The remaining syngas, hydrogen stream () and CO2 from an associated process are fed to methanol synthesis (), which produces methanol and a purge stream () supplied to the CO2 removal unit. The methanol is supplied to an acetic acid unit ()with the CO () to make acetic acid, which in turn is supplied to a VAM synthesis unit (). Oxygen for both the ATR and VAM synthesis can be supplied by a common air separation unit (), and utilities such as steam generation can further integrate the process.
