摘要:
This invention is directed to a method, and a system therefor, for recovering PFC using condensation by passing a PFC-containing feed stream into a condenser, preferably reflux condenser, to effect liquefaction into a PFC-containing condensate and a carrier gas stream, and passing the PFC-containing product into a mass transfer unit to fractionate the PFC-containing condensate into a high volatility PFC stream and a PFC product.
摘要:
A system for effectively generating refrigeration for use in putting a product fluid into an ultra cold condition wherein an active magnetic regenerator or a multicomponent refrigerant fluid cycle is integrated with a pulse tube system for receiving heat generated by the pulse tube system.
摘要:
A system for generating refrigeration and providing the refrigeration into a cryogenic rectification plant wherein, in addition to refrigeration generated by turboexpansion, further refrigeration for the plant is generated by a recirculating multicomponent refrigerant in a refrigeration circuit.
摘要:
An annular column, particularly useful for cryogenic rectification, comprising coaxially oriented, radially spaced cylindrical column walls defining a first column region, and a second column region between the walls, wherein different fluid mixtures are rectified in each of the first column and second column regions.
摘要:
A method for cleaning and recycling protective atmosphere for a float glass facility wherein contaminated protective atmosphere is cooled, preferably while scrubbing out particulates, compressed, and then purified by passage through a bed comprising water selective and hydrogen sulfide selective adsorbents.
摘要:
A cryogenic rectification system wherein a product boiler is incorporated into the primary heat exchanger without encountering boiling to dryness problems wherein liquid from the cryogenic rectification plant is processed in a phase separator upstream of the product boiler, and fluid from the product boiler is passed into the phase separator prior to recovery.
摘要:
A cryogenic air separation plant or a combined pressure swing adsorption plant and membrane separation plant is integrated with a float glass manufacturing system wherein oxygen from the plant is used for oxy-fuel combustion in the melt furnace and nitrogen from the plant is used as a protective atmosphere in the float glass forming chamber.
摘要:
A cryogenic rectification system for the separation of feed air wherein at least some of the feed air is liquefied upstream of the separation columns, all of the liquefied feed air is introduced into a higher pressure column, and then a portion of this liquefied feed air is withdrawn from the higher pressure column and in serial fashion introduced into a lower pressure column.
摘要:
A cryogenic rectification system for producing lower purity oxygen comprising a double column with a third column reboiled by feed air at an intermediate level and, optionally, in a staged manner at the bottom level.
摘要:
A single column cryogenic rectification system for producing lower purity oxygen wherein a major portion of the feed air is partially condensed in the column reboiler, the resulting vapor turboexpanded and then successively condensed in one or more vertically oriented stages within the column to enhance the generation of upflow vapor and reflux liquid for the column.
