Title: Process and apparatus for the regeneration of an ammoniacal liquid containing cuprous and cupric salts, used for removing carbon monoxide from gaseous mixtures under pressure
IPC: C10K1/12
Filed: 1957-05-22
Abstract: <PICT:0836050/III/1> In a process for the regeneration of an ammoniacal liquid containing cuprous and cupric salts which has been used to absorb CO from a gaseous mixture under pressure, the liquid is de-pressurized and heated by heat-exchange with regenerated liquid to expel most of the CO before passing to a reduction zone in which residual CO reduces some cupric salt to cuprous salt, the liquid leaving the reduction zone being heated by externally-supplied steam, after which it is passed to the heatexchanger in which the liquid to be regenerated is heated.  As shown, liquid to be regenerated is passed partly through a pressure reduction vessel 1 and partly through a scrubber 2 before entering a heat-exchanger 3 through which regenerated liquid from an oxidation tank 13 is passing.  The liquid thus heated to 50 DEG  C. is freed from most of its CO in a vessel 4 and enters a reduction zone 6 by lines 5; reduced liquid is withdrawn by line 7 and passed through a column 8 in countercurrent contact with vapours from a boiler 11 in which liquid from the column 8 is heated indirectly with steam to 82 DEG  C. to expel CO and other gases. Liquid from the boiler 11 passes into the oxidation tank 13 where the last traces of CO are oxidized to CO2 by cupric salt. Regenerated liquid, after passing through the heat-exchanger 3, is cooled in coolers 15 and 16 to 7 DEG  C. before entering a correction tank 17 wherein the composition of the liquid is brought to the following by the addition or use of, for example, NH3, CO2 and/or O2:-total copper content 125-130 gms./litre; cupric copper content 28-30 gms./litre; total ammonia content 152-155 gms./litre; carbon dioxide content 125 gms./litre; acetic acid content 40 gms./litre; free ammonia content 0.20-0.25 gram equivalents per litre.  Some of the liquid from the vessel 4 may by-pass the reduction zone 6 or both the reduction zone 6 and the column 8.  Gases and vapours from vessels 4, 6 and 7 are passed through the scrubber 2 and then, together with gases evolved in the vessel 1, are washed with water in a scrubber 24 to remove NH3.  Specification 680,849 is referred to.

Filed: 1926-06-29
Abstract: 255,837. Dyko, L. A. van. June 29, 1926- Polymerized vinyl chloride.-A polymer of vinyl chloride, which is soluble in monochlorbenzene and insoluble in acetone is obtained by exposing gaseous vinyl chloride, or a solution of it, in an organic solvent such as alcohol, methyl alcohol, monochlorbenzene, or ethylene chloride or bromide, to the action of ultra-violet rays, as from a mercury lamp, or to the action of sunlight, volatilizing unchanged vinyl chloride, extracting into acetone to remove the acetone-soluble polymer, and extracting the required polymer with monochlorbenzene, the polymers insoluble in both acetone and monochlorbenzene being thus removed. A catalyst such as a soluble lead salt may assist the action when polymerization is effected by sunlight or in solution. Alternatively, polymerization is effected as above, but is prolonged to obtain chiefly the polymers insoluble in both acetone and monochlorbenzene. After separation from unchanged vinyl chloride, the polymers are heated with an organic amine such as aniline or quinoline until they become soluble in monochlorbenzene.
