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 to 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.
