The commercialization of Integrated Gasification Combined-Cycle (IGCC) power has been aided by concepts involving the integration of air separation units (ASU) with the gas turbine combined-cycle module. Other processes, such as coal-based ironmaking and combined power and industrial gas production facilities, can benefit from the integration of these two units. It is known and widely accepted that an ASU which is optimally integrated with the gas turbine can increase overall IGCC power output, increase overall efficiency, and decrease the net cost of power compared to non-integrated facilities employing conventional low pressure cryogenic ASU`s. Depending upon the specific gas turbine, gasification technology, NOx emission specification, and other site specific factors, various approaches to the production of oxygen and nitrogen will be optimal. Advancements in both air separation and gas turbine technologies offer new integration opportunities to further improve performance and reduce costs. This paper will review basic integration principles and describe advanced concepts based on emerging technologies for the co-production of oxygen and electric power.
