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 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.
摘要:
A pulse tube system for generating refrigeration for uses such as in magnetic resonance imaging systems wherein an oil-free compressor operating at a higher frequency generates pulsing gas which undergoes a frequency reduction and drives the pulse tube system at a more efficient lower frequency.
摘要:
A cryocooler system having at least one flow straightener which has a system of grooves on its perforated surface for enhancing gas flow uniformity through the system wherein pulsing gas which does not initially pass through the flow straightener through a perforation flows along the surface of the flow straightener within a groove prior to passing through a perforation and is effectively redistributed across the surface of the flow straightener and thus the cross section of the regenerator or thermal buffer tube.
摘要:
A refrigeration generation system wherein a frequency modulating mechanical resonator is positioned between a pressure wave generator and a cryocooler and serves to reduce the frequency of the oscillating gas emanating from the pressure wave generator so that it more closely comports with a more efficient operating frequency of the cryocooler.
摘要:
A method and apparatus for refrigerating and, if desired, liquefying an industrial gas wherein a multicomponent refrigerant fluid is used to generate refrigeration in a single circuit which includes a single phase separation and recycle after an initial heat exchange stage.
摘要:
A system for providing refrigeration to a heat load, especially over a larger temperature range and at a cryogenic temperature, wherein pulse tube refrigeration cools a heat transfer medium to provide higher level refrigeration to a refrigeration fluid, and lower level refrigeration is provided to the refrigeration fluid using a non-pulse tube system.
摘要:
An industrial gas liquefaction cycle employing a main refrigeration circuit to supply low level refrigeration to the industrial gas, and a forecooling circuit employing an azeotropic mixture to provide high level refrigeration to the refrigerant fluid recirculating within the main refrigeration circuit.
摘要:
A method for more efficiently liquefying industrial gas wherein refrigeration for the liquefaction is generated using a defined multicomponent refrigerant fluid and provided by a single flow circuit over a wide temperature range from ambient to cryogenic temperature.
