Patent GB-846511-A (GB)
Title: Process for the treatment of gaseous mixtures of carbon dioxide and ammonia
IPC: C01C1/12
Filed: 1957-10-30
Abstract: In the production of melamine by heating urea to 300-600 DEG C under a pressure of added ammonia of 50-1000 ats. and anhydrous conditions, the carbon dioxide and ammonia gases produced simultaneously are contacted with dimethyl formamide, ethylene glycol or diethylene glycol whereby all the carbon dioxide is converted to ammonium carbamate (see Group III) which may be converted to urea for further melamine production.ALSO:<PICT:0846511/III/1> Anhydrous gaseous mixtures of carbon dioxide and ammonia containing 5-20% by weight CO2 are contacted with dimethyl formamide, ethylene glycol or diethylene glycol whereby substantially all of the carbon dioxide, and sufficient ammonia to react therewith to form a carbamate, are absorbed.  Any unabsorbed excess of ammonia may be recovered in the pure state: where unreacted ammonia remains dissolved in the organic compound and a major portion of the ammonium carbamate forms as a precipitate, the latter may be separated to leave a solution which may be re-used for absorption.  The resultant carbamate may be sublimed and recondensed and uncondensed gases recycled for absorption.  By heating at a higher temperature ammonia and carbon dioxide may be recovered: similarly if the carbamate does not precipitate, the solution may be heated to give carbon dioxide and ammonia by decomposition.  As shown in Fig. 2, the mixture of gases may be introduced into a tower 1 and there contacted in counter-current with the organic liquid at 0-20 DEG C.  The resultant carbamate suspension is then passed to a filter 3 from which the absorbent passes to a collecting tank 6 for recycling.  When full, filter 3 is shut off and filter 4 employed.  Filter 3 is then heated to about 60 DEG C. and passed as a vapour into vessel 5 where it is condensed, any ammonia and carbon dioxide formed being recycled. Alternatively the filter may be heated sufficiently to decompose the ammonium carbamate into ammonia and carbon dioxide which are passed to a urea production plant.  Suitable mixtures of ammonia and carbon dioxide are obtained in the production of melamine from urea.
