Abstract

903,462. Cold separation of gas mixtures. LINDE'S EISMASCHINEN A.G. GES. FUR. Sept. 21, 1959 [Sept. 24, 1958], No. 32096/59. Class 8(2). In a two stage gas mixture e.g., air rectification process wherein a liquid component e.g., oxygen is withdrawn from the main column 6 through a duct 16 and is pressurized in a pump 17 before being revaporized in a heat exchanger 19 and discharged as product at ambient temperature through a duct 20, extra cold is provided by withdrawing vapour from the prerectification column 5 through a duct 21, passing it through coils 22 embedded in conventional nitrogen regenerators 2 for cooling incoming air, partially liquefying the so warmed vapour in the exchanger 19 is countercurrent to the pressurized liquid oxygen, separating the liquid in a chamber 24 and returning it through ducts 25, 3 to the column 5 and warming the vapour in an exchanger 68 before expanding in a turbine 29 and feeding to the column 6. As shown, warming in exchanger 68 is effected by nitrogen withdrawn from the head of column 5 through a duct 63 warmed in coils 64 within the regenerators 2, compressed at 65 to about 25 atmospheres and freed of its heat of compression in an exchanger 67; nitrogen leaving the exchanger 68 being mostly liquid and after being supercooled in an exchanger 69 is in part returned to the column 5 and in part passed through a duct 70 and a chamber 81 to serve as washing liquid in a column 71 for separating a mixture of hydrogen and nitrogen from admixture with carbon monoxide and methane. The crude gas is supplied to the column 71 through a duct 76 heat exchangers 73, 74, 79, 80 traversed by the counterblowing product mixture, the vessel 81 and a duct 82. Liquid carbon monoxide and methane is withdrawn from the sump 83 and after being vaporized in vessel 81 and exchangers 69, 66 is discharged through a duct 85. Cooling of crude gas by exchangers 73, 74 is assisted by a brine circuit 86 which includes a heat exchanger 87 in the oxygen discharge duct 20. In a modification heating of the vapour from separator 24 prior to expansion in turbine 29 is effected by a portion of the vapour withdrawn from duct 21 through a duct 32, Fig. 1 (not shown) and compressed to about 25 atmospheres.
