PRESSURIZATION PSA SYSTEMS FOR THE PRODUCTION OF HIGH PURITY PRODUCT GAS

摘要

Processes for the production of an inert gas-rich product gas from pressure swing adsorption are provided wherein the pressurization step is carried out by the use of feed gas only in a two step late feed profile, or by product gas and feed gas with the feed gas entering in either a typical one-step feed profile or in the two step late feed profile above.
