COMPARATIVE THERMODYNAMIC ANALYSIS OF GAS MIXTURE SEPARATION AND LIQUEFACTION METHODS

摘要：

Gas separation technologies play key role in technical gases production, natural gas processing,helium extraction and separation, CO2 sequestration and other processes. The presently used methods include cryogenic rectification, adsorption processes and membrane separation. We compare thermodynamic efficiencies of the above technologies with a ideal reference process characterized by minimum work input. The applicability of each method is analyzed with respect to the gas purity and installation capacity. We pay special attention to a small scale nitrogen generation unit based on a gas mixture fed Joule-Thomson refrigerator coupled with membrane air separation unit.
