Abstract
The present invention is directed to a gas separation system for the recovery of pressurized, substantially pure, constituent gaseous products from a gas mixture using a single pressure distillation column with the feed gas as the working fluid for column reflux and reboil. The present invention is particularly useful for the separation of air into pressurized oxygen and nitrogen products. In an air separation process the nitrogen stream is utilized as secondary cooling gas for a combuster, the exhaust gas of which when fed to a gas turbine can provide air feed compression energy and/or electrical power generation for export or process operation when a generator is attached to the turbine.
