Abstract

795,500. Refrigerating. RUHRGAS AKT.- GAS. July 19, 1956 [July 20, 1955], No. 22398/56. Class 29 [Also in Groups XXVI and XXVIII] To recover energy from heat freed during the cooling of gases compressed in one or more stages, a vapour employed as cooling means in heat exchangers arranged subsequent to the compression stages is superheated in the heat exchangers and conveyed to an expansion machine. The heavy line indicates the course of the compressed gas, i.e. it passes through the first compression stage 1, is cooled in the heat exchanger 1a, passes through compressor 2 and is cooled in heat exchanger 2a, is further cooled in deep-cooler 3 and then heated in precooler 10 where it cools the compressed gas being fed to the deepcooler. The cooling means (CF2Cl2, carbondioxide, propane, isobutane, or ethane) passes at a pressure above the critical pressure from the pump 4 into the heat exchangers 1a and 2a where it is evaporated and highly superheated, performs work in the expansion machine 5, is liquified in the water-cooled condenser 6 and returns to pump 4. A portion of the condensate passes through a choke nozzle 7, expands, passes through the deep-cooler 3 for the compressed gas, being transformed into a gaseous condition in which it is compressed by a compressor 9 and fed into the line leading to the condenser 6.
