VERFAHREN ZUR ERZEUGUNG VON KOHLENMONOXID UND METHANOL

摘要

A side stream (10) of the synthesis gas is branched off. The carbon dioxide contained is separated (11) and recycled to the synthesis gas generator (5). The carbon dioxide-free gas is subjected to a separation process (16) producing carbon monoxide. Separated hydrogen is returned to the synthesis gas, which is converted in a methanol synthesis process (22) to methanol and purge gas.
