Abstract:
A heat-transfer and mass-transfer integrated core comprising:an entrance passage cooling an incoming feed air stream;a rectification section comprising at least one passage facilitating mass transfer of the feed air stream to produce a first liquid stream enriched in a heavy component and a first vapor stream enriched in a light component;a first exit passage in a heat exchange relationship with said entrance passage, said first exit passage warming the first vapor stream and discharging the first vapor stream from said integrated core;a separation section comprising at least one passage in a heat exchange relationship with the at least one passage of said rectification section, said separation section facilitating separation of the first liquid stream into a second liquid stream and a second vapor stream;a second exit passage, in a heat exchange relationship with said entrance passage, warming and discharging the second vapor stream from said integrated core; anda vaporization section comprising at least one passage in a heat exchange relationship with said entrance passage, said vaporization section vaporizing the second liquid stream, and discharging the vaporized second liquid stream from said integrated core.
