Abstract
The generation of electric power and the separation of a feed gas mixture containing oxygen and nitrogen are carried out by combusting an oxidant gas and fuel in a combustion engine to generate shaft work and a hot exhaust gas, utilizing the shaft work to drive an electric generator to provide the electric power, compressing the feed gas mixture and separating the resulting compressed feed gas mixture into two or more product gas streams with differing compositions, heating one of the product gas streams by indirect heat exchange with the hot exhaust gas, and work expanding the resulting heated product gas stream to generate shaft work and yield an expanded product gas stream. The feed gas mixture can be air and the combustion engine can be a gas turbine combustion engine, and the air separation process preferably is operated independently of the gas turbine combustion engine.
