Abstract
An improved continuously operating adsorption process for the purification and separation of gaseous mixtures by pressure swing adsorption is disclosed. The improvement is achieved by heating the gaseous mixture to be separated by heat exchange with the vacuum pump which consists of at least two in series operating pumps. The present process is especially suited for efficiently producing oxygen-enriched air.
