Abstract

1,246,987. Cold separation of gas mixtures. MESSER GRIESHEIM G.m.b.H. 16 Dec., 1968 [21 Dec., 1967], No. 59761/68. Heading F4P. The sump of a rectification column 3, Fig. 1, fed through a line 1 with a binary gas mixture components having widely differing boiling points e.g., methane and ethylene at a pressure between 2À2 and 5 ats. is heated by a twocomponent circulating gas mixture of methane and ethylene forced by a compressor 6 at between 15 and 18 ats. through a line 7 and the sump heater 9, and the resulting partly condensed circulating mixture is separated at 11 into a methane-rich gas and an ethylene-rich liquid which gas is then liquefied in a heat exchanger 13 in counterflow to the separated liquid withdrawn through a line 12 and expanded at a valve 14; the so liquefied methane-rich recirculating component then being expanded at a valve 16 and used at 17 to cool the column head after which the so-vaporized circulating methane in a line 15 is added to the valveexpanded ethylene and returned through a line 18 to the compressor inlet. Product methane from column 3 is withdrawn at 4a and product ethylene is withdrawn at 5. In a modification the circulating gas also provides additional cold to the column 3, Fig. 2, the feed gas mixture to which is subjected to a preliminary separation at 19 into crude liquid ethylene which is expanded at a valve 21 into the column 3 and into crude gaseous methane which is further cooled and partly condensed at 23, 24, separated at 25 into a liquid mixture of methane and ethylene which is expanded at 27 into column 3, and into gaseous methane which is withdrawn as product through a line 30; the cold requirements of heat exchanger 23 being met by withdrawing at 28 part of the liquid ethylene from separator 11, expanding at 29, passing it through exchanger 23 and returning to compressor 6.
