Abstract
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.
Claims17
An improved process for providing a feed gas for a chemical reaction and for separating a gaseous reaction product from the gaseous mixture obtained from a reaction to which the feed gas is submitted, wherein the feed gas is obtained by the fractionation of a crude gas mixture containing the feed gas, as well as a carrier gas or carrier gas mixture, and in which the feed gas is reacted only incompletely in the reaction, and wherein the unreacted proportion is to be recycled into the reaction, the improvement comprising conducting the fractionation of the crude gas mixture and the separation of the gaseous reaction product in the same adsorption plant containing cyclically reversible adsorbers, and operating by the pressure swing method.
An improved process for providing a feed gas for a chemical reaction and for separating a gaseous reaction product from the gaseous mixture obtained from a reaction to which the feed gas is submitted, wherein the feed gas is obtained by the fractionation of a crude gas mixture containing the feed gas, as well as a carrier gas or carrier gas mixture, and in which the feed gas is reacted only incompletely in the reaction, and wherein the unreacted proportion is to be recycled into the reaction, said process comprising:
- supplying a crude gas mixture, including components of a feed gas for a chemical reaction and of a carrier gas or carrier gas mixture, to a single adsorption plant which includes plural adsorbers;
- adsorbing one of the crude gas mixture components for separating said feed gas therefrom in said single adsorbing plant;
- feeding said gas from said single adsorption plant into a reactor and reacting it therein for obtaining a gaseous mixture including a gaseous reaction product and feed gas;
- compressing and feeding said gaseous mixture into said single adsorption plant for having said gaseous reaction product separated from said gaseous mixture;
- and removing said gaseous reaction product from said single adsorption plant and refeeding the unreacted feed gas into the reactor for cyclically repeating the process.
