Cryogenic air separation method for producing high pressure oxygen

摘要

The present invention relates to a cryogenic air separation method for providing high pressure oxygen for oxygen burning of fuel (eg, carbonaceous fuel). This air separation method can be directly incorporated into a closed cycle power generation method using a working fluid such as CO2. Advantageously, the present air separation method eliminates the need for intercooling between air compression stages, and on the contrary provides a step of recirculating adiabatic compression heat during the process steps of a further method where further heat supply is advantageous. be able to.
