摘要： A method of producing gaseous oxygen in accordance with a variable demand cycle in which pumped liquid oxygen from a double column air separation unit is vaporized within a mixing column. During low demand phases, excess liquid oxygen is stored within a storage tank and used to augment the liquid oxygen to vaporized during the high demand phase. Reflux to the lower pressure column of the air separation unit is kept constant by storing liquid with column bottoms produced within the mixing column during the high demand phase for use in the low demand phase when less liquid oxygen is vaporized and therefore less column bottoms is produced in the mixing column.

摘要： For the low temperature fractionation of air with variable oxygen production, compressed, prepurified, and cooled air (conduit 5) is initially fractionated in the high pressure stage 10 of a two-stage rectification 9. The thus-produced bottom liquid is further separated in the low pressure stage 11. Liquid nitrogen 14 from the high pressure stage 10 and liquid oxygen from the low pressure stage 11 can be stored intermediarily in tanks 35 and 32. An enriched liquid air tank 40 is additionally provided in order to store bottom liquid 12 from the high pressure stage 10. In case of increased oxygen production, the internal rate of flow in the high pressure stage 10 can be raised; and simultaneously the internal rate of flow in the low pressure stage 11 and the reflux ratios in both rectifying stages 10, 11 can be maintained constant. The constant reflux ratio in the low pressure column permits the argon bubble concentration to remain high, permitting a substantially maximum rate of separation of the argon in a crude argon column.

摘要： A method of operation of a thermal power plant having an air separation system with a plurality of air storage unit (ASU) compressors and a liquid oxygen/liquid air (LOX/LA) storage facility for oxyfuel firing of fossil fuel and a power plant having a control system to perform the same are described. The method is characterized by the step of controlling the net power output of the plant in response to short term variations in grid demanded net plant output by dynamically adjusting the works power of the ASU compressors preferably in conjunction with co-ordinated changes in firing demand. The method is in particular a method to produce an improved primary and secondary response to transient changes in grid demand and to provide accurate response to load dispatch ramps.

摘要： 826,298. Cold separation of air. SOC. L'AIR LIQUIDE, SOC. ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES G. CLAUDE. Sept. 10, 1957 [Sept. 25, 1956], No. 28532/57. Class 8(2). In an air rectification process wherein liquid oxygen is withdrawn from the base of the low pressure section 8 of a conventional double column 6 irto a reservoir 20, and gaseous nitrogen is withdrawn through a duct 22 and used to cool and partly liquefy feed air traversing one or other of a pair of alternating regenerators 4A, 4B, extra refrigeration is supplied to column 8 by feeding liquid air at a constant rate from an external reservoir 61 which is itself supplied by a compressor 38 discharging through a purifier 39 and heat exchangers 31, 30 in countercurrent to liquid oxygen from reservoir 20 and also in countercurrent to an unliquefied portion of air leaving exchanger 31 after expansion in an engine 52. In a modification wherein the auxiliary air liquefaction plant is remote from the rectification plant, liquid oxygen is transported therefrom in a container and forced by one or both of a pair of pumps in parallel through the exchangers 30, 31 and when empty of liquid oxygen the container is filled with liquid air and returned to the rectification plant.
