Abstract

1280438 Methanol synthesis and purification CHEMICAL CONSTRUCTION CORP 23 March 1971 7667/71 Heading C2C The invention comprises a process for the catalytic synthesis of methanol wherein the synthesis gas, prior to conversion to methanol, is cooled in at least one stage and the product gas, after methanol synthesis, is cooled and the separated methanol is distilled in at least one column having a lower reboiler, the latter being heated by direct or indirect (in which the heat is transferred by a circulating fluid) heat exchange with the feed gases or product gas. In a preferred embodiment, the methanol is distilled in a three column system, the bottom of the first and third columns being heated by direct heat exchange with the hot synthesis gases derived from the steam reformation of a fluid hydrocarbon and the bottom of the second column being heated by indirect heat exchange with the product gases from the methanol synthesis step.
