Title:
CRYOGENIC AIR SEPARATION METHOD FOR PRODUCING OXYGEN AT HIGH PRESSURES
Document Type and Number:
WIPO Patent Application WO/2018/042336
Kind Code:
A3
Abstract:
The present invention relates to a cryogenic air separation process that provides high pressure oxygen for an oxy-fired combustion of a fuel (e.g., a carbonaceous fuel). The air separation process can be directly integrated into a closed cycle power production process utilizing a working fluid, such as C02. Beneficially, the air separation process can eliminate the need for inter-cooling between air compression stages and rather provide for recycling the adiabatic heat of compression into a process step in further methods wherein an additional heat supply is beneficial.
