Successful commercialization of COREX technology requires economical use of the export gas. One such use for this gas is the production of power, especially in a high efficiency combined cycle process. Optimal integration of the cryogenic air separation unit (ASU) with the gas turbine combined cycle module involves significant trade-offs. Issues of oxygen purity, argon production, power use efficiency and power production efficiency must all be addressed. Air Products has been aggressively involved in evaluating COREX opportunities and has supplied the oxygen plant for the COREX facility at POSCO`s Pohang Works. In addition, Air Products has supplied ASU`s with no integration, nitrogen only integration and full air and nitrogen integration at three different Integrated Gasification Combined Cycle (IGCC) power plants. This paper will discuss the process, location, operating philosophy and other trade-off issues involved in the decision making process, regarding optimal oxygen and power production associated with COREX operation.
