Abstract
From the CO-containing stream of process gas obtained in a process for the treatment of a CO-containing stream of process gas, which is obtained in the production of pure synthesis gas from raw gas in the partial oxidation of heavy oils, petroleum coke or wastes, or in the gasification of coal, or when processing natural gas or accompanying natural gas, COis removed physisorptively or chemisorptively, and the solvent loaded with COis expanded to a lower pressure for the desorption of CO. In order to generate COas pure as possible, the contaminated COis condensed to at least 60 bar[a] or below its critical temperature to at least 70 bar[a], and the impurities contained in the liquid COare removed by stripping with gaseous COguided in counterflow.
