Abstract
1,129,939. Recovering carbon dioxide. OSTERREICHISCHE STICKSTOFFWERKE A.G. 21 April, 1967 [2 May, 1966], No. 18597/67. Heading C1A. [Also in Division B1] A gas mixture containing carbon dioxide, ammonia and water-vapour is treated in tower 2 with a countercurrent stream of water (or dilute ammonium carbonate solution) whereby the bulk of the CO 2 and some of the NH 3 dissolve in the water; the solution so obtained is heated under atmospheric pressure in column 5 in order to remove free NH 3 , and the solution is then pumped into column 9 where it is heated to 120-150‹ C. under a pressure of 5 to 20 atmospheres whereby gaseous CO, is liberated and leaves the head of the column 9. The CO 2 is washed with water in column 10, which is maintained at a pressure of 5 to 20 atmospheres, and purified CO 2 is withdrawn from the head of column 10. The solution withdrawn from the sump of column 9 may be returned to ab. sorption tower 2; and the NH 3 obtained at the head of column 5 is also passed to tower 2. Ammonia is withdrawn from the top of tower 2. The initial mixture containing CO 3 , NH 3 and water-vapour may be derived from the synthesis of melamine from urea.
