摘要:
A refrigeration system wherein an ammonia refrigerant fluid in a cascade refrigeration circuit provides auxiliary refrigeration to a multicomponent refrigerant fluid which passes from an autorefrigerator to provide refrigeration to a heat load.
摘要:
A cryogenic air separation system wherein pressure energy is supplied by a bridge machine having one or more booster compressors and a multicomponent refrigerant fluid compressor of a multicomponent refrigerant fluid circuit, all of the compressors of the bridge machine driven by power supplied through a single gear case.
摘要:
A cryogenic nitrogen production plant wherein all the heat transfer steps, and preferably all the heat transfer and separation steps, are carried out in a brazement which receives feed air and from which is recovered product nitrogen.
摘要:
A system wherein flashoff losses from cryogenic liquid tankage are reduced wherein fluid from the tankage is condensed and subcooled against refrigeration bearing refrigerant fluid generated by an exogenous refrigeration system.
摘要:
A system for generating refrigeration wherein a multicomponent refrigerant is compressed in a compressor lubricated with polyalphaolefin-based oil, the oil is removed from the compressed refrigerant, and the compressed refrigerant is expanded to generate refrigeration at a cryogenic temperature for provision to a refrigeration receptor.
摘要:
A refrigeration system wherein refrigeration is generated at a relatively steady output by a refrigeration circuit and passed into a coupling fluid for transfer to a refrigeration load using a coupling fluid stabilizing circuit having a stabilizing reservoir.
摘要:
A cryogenic air separation system comprising an integrated core and typically including a double column wherein incoming feed air is cooled in the core which also processes a stream from the double column. A separating section of the core processes a stream from the double column to form product.
摘要:
A cryogenic air separation system, which may be used to produce ultra high purity nitrogen or ultra high purity oxygen, wherein kettle liquid is vaporized in two steps using a split kettle top condenser and vapor from the first step compressed and then recycled to the cryogenic rectification column.
摘要:
A method for generating refrigeration for application to a heat load, especially at very cold temperatures, using an environmentally benign working gas such as air and using an upstream precooling circuit to reduce or eliminate inefficiencies stemming from warm end pinch.
摘要:
A cryogenic air separation system wherein an integrated core receives and cools an incoming feed air stream, a rectification section facilitates mass transfer of the feed air stream, a separation section in a heat exchange relationship with the rectification section processes fluid from the rectification section, and a section in a heat exchange relationship with an entrance passage discharges fluid from the integrated core.
