Abstract

1,122,673. Cold separation of gas mixtures; refrigeration. UNIVERSAL OIL PRODUCTS Co. 24 Nov., 1965 [3 Dec., 1964], No. 49860/65. Headings F4H and F4P. A low temperature fractional distillation column 18 is operated in conjunction with a heat pump employing a multi-stage refrigeration system in which vaporous refrigerant is passed from a compression stage higher than the lowest of multi-stage compressor 43 by line 30 to heat the reboiler 28 of the column, the cooled refrigerant is separated in separator 35 into vapour in line 47, which is returned to the highest stage of compressor 43, and liquid in line 36, which is expanded into intermediate pressure load 40 and again separated in separator 38, from which liquid in line 39 is taken to cool the overhead condenser 20 of the column then returned to the lowest stage of compressor 43, and vapour from the highest stage of the compressor is expanded into high pressure load 33 and then passed to separator 35. Part of the liquid refrigerant in line 39 is expanded into low pressure load 48 and returned to the lowest compression stage while vapour from separator 38 is returned to an intermediate compression stage. The description relates to separating an ethane-ethylene mixture using propylene as refrigerant and the cooling facilities of 33, 40 and 48 are used in earlier stages of obtaining the liquid distillation feed from a hydrocarbon pyrolysis fraction.
