FREMGANGSMAATE VED TILVEIEBRINGELSE AV EN BRUKSGASS FOR EN KJEMISK REAKSJON OG VED ADSKILLELSE AV ET GASSFORMIG REAKSJONSPRODUKT

摘要

A process for providing a feed gas for a chemical reaction and for separating a gaseous reaction product from the gaseous mixture obtained by the reaction, wherein the feed gas is obtained by the fractionation of a crude gas mixture containing this feed gas proper, as well as a carrier gas or carrier gas mixture, and is reacted only incompletely in the reaction, and wherein the unreacted proportion is to be recycled into the reaction, the improvement wherein the fractionation of the crude gas mixture and the separation of the gaseous reaction product are conducted in a single adsorption plant operating by the pressure swing method and containing cyclically reversible adsorbers.
