    摘要: A compressed air stream is cooled to a temperature suitable for its rectification within a lower pressure heat exchanger and a boosted pressure air stream is liquefied or converted to a dense phase fluid within a higher pressure heat exchanger in order to vaporize pumped liquid products. Thermal balancing within the plant is effectuated with the use of waste nitrogen streams that are introduced into the higher and lower pressure heat exchangers. The heat exchangers are configured such that the flow area for the subsidiary waste nitrogen stream within the higher pressure heat exchanger is less than that would otherwise be required so that the subsidiary waste nitrogen streams were subjected to equal pressure drops in the higher and lower pressure heat exchangers. This allows the higher pressure heat exchanger be fabricated with a reduced height and therefore a decrease in fabrication costs.

    摘要: A process for the purification of the low-boiling constituents of a compresed gas mixture, such as a mixture comprising a carbonaceous gas, by cooling to low temperatures in cyclical alternated regenerators to condense high-boiling constituents of the gas mixture comprising (1) passing the gas mixture through a first regenerator from the warm end to the cold end of the same to cool the gas mixture and to condense the high-boiling constituents of the mixture thereby producing a purified gas stream; (2) passing a scavenging gas which is at a lower pressure than said gas mixture in the first regenerator through a second regenerator from the cold end to the warm end of the same to clean this second regenerator and to re-evaporate the high-boiling constituents, (3) passing at least part of the purified gas stream through a third regenerator from the cold end to the warm end of the same to re-cool this third regenerator, preferably to the temperature of the first regenerator, and (4) compressing and recycling at least part of the scavenging gas which has passed through the second regenerator through the first regenerator from the warm end to the cold end and repeating the process as defined above.

    摘要: A temperature control method for a reversing type heat exchanger group wherein an outlet temperature of reheating gas of an arbitrarily selected reversing type heat exchanger which serves as a reference in the reversing heat exchanger group is rendered equal in value to a reference control temperature set beforehand in such a manner so as to satisfy the sweeping temperature difference. The outlet temperatures of the reheating gas in the other reversing type heat exchangers of the reversing type heat exchanger group are rendered equal in value to the outlet temperature of the reheating gas in the reversing type heat exchanger serving as the reference. Thus, the temperature of the cold end of all of the reversing type heat exchangers of the reversing type heat exchanger group are caused to be balanced equally whereby ice and dry ice deposited on the feed water channels can be effectively removed by a sweeping action.

    摘要: A process and apparatus is provided for separation of a hydrogen-containing gaseous mixture, wherein the gaseous mixture is separated into a condensate fraction and a crude hydrogen fraction containing the hydrogen in addition to other residual components. Separation is accomplished by refrigeration under pressure in at least two reversible regenerators which are charged alternately with crude gas and scavenging gas. The crude hydrogen, after further cooling by partial condensation or by a washing step with liquid nitrogen, is freed of the residues of other components. The purified hydrogen product, which can optionally contain nitrogen, is engine-expanded for the purpose of producing refrigeration and then conducted through heat exchange coils in at least one of the regenerators.
