<p>A method for the production of syngas from methanol feedstock is disclosed. Themethanol 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, carbonmonoxide, and carbon dioxide. The carbon dioxide (122) is separated out and thehydrogen and carbon monoxide mixture (124) is fed to a cold box (126) where it isseparated into hydrogen-rich and carbon monoxide-rich streams (130, 128).The separated carbon dioxide (122) can be recycled back to the partial oxidationreactor (112) as a temperature moderator if desired. The carbon monoxide-richstream (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 acidprecursor. Optionally, an ammonia synthesis unit (144) and/or vinyl acetatemonomer synthesis unit (156) can be integrated into the plant.</p> |
