Abstract

1,217,705. Cold separation of gas mixtures; surface condensers. CHEPOS, ZAVODY CHEMICKEHO A POTRAVINARSKEHO STROJIRENSTVI. 10 July, 1968, No. 32833/68. Headings F4P and F4S. Cooling of a converted ammonia synthesis gas mixture so as to condense the ammonia is effected by passing the gas mixture through an inlet 32, Fig. lb, leading to a chamber 18 formed in the end plate 26 of a nest of U-tubes 23 within a casing 15 and which tubes exhaust into a chamber 19 formed between the end plate 26 and the end plate 22 of a second nest of U- tubes 8 within a casing 4 cooled by a boiling refrigerant, passing the so-cooled and partially condensed mixture through an outlet chamber 20 and a duct 21 to a liquid ammonia separator (not shown), withdrawing cold uncondensed nitrogen and hydrogen therefrom and passing through an inlet 27 to the shell space of casing 15 to effect preliminary cooling of the feed gas mixture traversing the nest of U-tubes 23 and thereafter discharging the nitrogen and hydrogen through an outlet 33. The shell space of casing 15 contains baffle plates 24, 25. In a modification the apparatus is mounted vertically, in a further modification the casing 15 of the preliminary cooler 2, Fig. 3, is formed with feed gas mixture inlet and outlet chamber 30, 31 bounded by the end plates 26 of two nests of U-tubes in parallel and by a horizontal wall 29 therebetween. The casing 4 is similarly constructed with two nests of U-tubes in parallel which discharge through an outlet 7 into a liquid ammonia separator 34 from which the cold gaseous hydrogen and nitrogen is withdrawn and passed through lines 35 to the shell spaces of casing 15. Refrigerant vapour generated in each shell space of casing 4 is exhausted through a liquid separator 10 and an outlet 28.
