    摘要： An integrated steam-ammonia power cycle is disclosed which achieves a close match to a glide heat source such as exhaust from a gas turbine, and which also eliminates sub-atmospheric pressure operation. With reference to FIG. 1, the exhaust heats in sequence steam superheater 107; steam boiler 105; feedwater preheater 104 plus ammonia superheater 103; and ammonia preheater 102. Steam is expanded to at least 17 psia in turbine 108, then condensed to boil ammonia in boiler 110. Superheated ammonia is expanded in turbine 112, and condensed in condenser 114. Feed ammonia is preheated in at least two parallel preheaters.

    摘要： The efficiency and capacity of an air compressor (10) (FIG. 1) are increased by pre-cooling the inlet air to below the dew point in air chiller (11), and then injecting the resulting condensate into the chilled air in the form of fog-sized droplets in a fogger (16). The advantages extend to combustion engines, and especially to regenerative combustion turbines.

    摘要： A non-diabatic vapor-liquid contact device is disclosed which achieves high heat transfer effectiveness without sacrificing mass transfer effectiveness. Referring to FIG. 2, a helical coil of crested tubing 84 is contained within the annualr space between shrouds 82 and 83. Liquid flows downward through the annulus, and vapor flows countercurrently upward. The mass exchanging fluids pass through the space between tube crests and the shroud, achieving very effective mixing. Heat transfer fluid is flowed through the tubing via connections 87 and 88. The heat and mass transfer is preferably additionally enhanced by interspersing contact media with the coiled tubing, either longitudinally or radially.

    摘要： Method and apparatus are disclosed for obtaining more refrigeration from a cold pressurized stream of nitrogen being expanded to discharge pressure, particularly in an air separation plant. Referring to FIG. 1, cold expansion in 1 is followed or preceded by warm compression in 2 of at least part of the same stream being expanded. The net result of reduced N.sub.2 to expansion is more LN.sub.2 reflux available to increase O.sub.2 recovery, without import of additional power or substantial increase in capital cost.

    摘要： The inefficiency of the nitrogen stripping section of a high purity oxygen-producing air distillation plant is reduced. This allows increased recovery of byproduct argon and in some cases increased recovery of refrigeration work also. The improvement is obtained by evaporating kettle liquid with condensing argon rectifier vapor in two sequential stages, to yield vapor streams respectively having more and less O.sub.2 content than the kettle liquid, and separately feeding them to the N.sub.2 removal column. The improvement is applicable to both dual and triple pressure processes. Referring to FIG. 1, kettle liquid is supplied via valve 11 to the top of contactor 18, and overhead reflux condenser 13 of argon rectifier 14 reboils the bottom of contactor 18. Vapor streams of differing O.sub.2 composition are withdrawn from above and below 18.

    摘要： The invention provides a means of producing high purity nitrogen at high recovery with lower energy requirement than has been possible heretofore. This is done with an elevated pressure dual pressure distillation column arrangement wherein the low pressure column (at about 4 ATA pressure) (component 102 in FIG. 1) is reboiled by partially condensing supply air in 103 and is refluxed both by direct injection of LN.sub.2 from the HP rectifier 105 plus latent heat exchange with depressurized LP column bottom liquid in 114, and the HP rectifier is refluxed by latent heat exchange with either LP column intermediate liquid in 106 and/or depressurized kettle liquid.
