Method and apparatus for the production of nitrogen for use as an inert gas

摘要

An arrangement for the production of nitrogen to be used as an inert gas in which carbon dioxide and water vapor are separated from a gas mixture consisting essentially of nitrogen and carbon dioxide. Two tanks connected in parallel have molecular beds through which the gas mixture is passed alternatingly. When the gas mixture is passed through one tank for adsorption purposes, then the other tank is being desorbed by a gas stream leaving the first tank and consisting of nitrogen. The stream of gas through a tank during the desorption phase is opposite to the direction of the gas flow during the adsorption phase.
