Abstract
1462117 Separating NH 3 and CO 2 BASF AG 5 April 1974 [7 April 1973] 15216/74 Heading B1L A process for separating a gas mixture comprising NH 3 and CO 2 comprises mixing the gas mixture in at least one mixing zone with a solvent which preferentially absorbs NH 3 , and separating non-absorbed gas mixture from the solvent after the or each mixing step, the residence time of the gas mixture in the or each mixing zone being not greater than 0.1 sec. The solvent may be water, ethylene glycol or glycerol. The temperature of solvent issuing from the mixing zone(s) is -5 to 50C. In the shown embodiment the gas is mixed with solvent at 3 to give an ammonium carbonate solution and a CO 2 -enriched non- absorbed gas which are separated in vessel 1. The non-absorbed gas is further mixed with solvent at 6 and the resultant gas (i.e. substantially pure CO 2 ) separated in vessel 5 is discharged via washing zone 21. Solution removed from the vessel 1 is passed through heat exchanger 12 to distillation column 13. Gas evolved in column 13 is passed to a condensation section above tray 16 to produce substantially pure NH 3 which is vented and an ammonium carbonate solution which is evaporated at 20 and fed to mixing zone 3. Unevaporated solution from column 13 is passed through heat exchanger 12 and recycled for use in the mixing zones 3 and 6.
