Cryogenic air separation plants produce purified oxygen, nitrogen and argon for the steel, chemical, food processing, semiconductor and health care industries. Cryogenic temperatures (–170 to –190 ◦C) are achieved via turbine expansion. Electricity required to power gas turbines represents the largest operational cost in air separation plants. Continued deregulation of the electric utility indu...
