| titleOfInvention | Method for preparing ammonia from urea |
| abstract | (a) In situ heating of an aqueous solution of urea or a mixture of urea containing biuret or ammonium carbamate in a hydrolysis reactor to yield a gaseous ammonia-containing product essentially free of urea, biuret or ammonium carbamate Wherein the temperature and pressure are maintained by heat entering the reactor; (b) separating the gaseous ammonia-containing product from the liquid aqueous reaction medium at the operating pressure; (c) maintaining the liquid reaction medium in the reactor for further conversion to gaseous ammonia and carbon dioxide and / or recycling at least a portion of the reaction medium to the reactor, urea dissolver or the feed solution to the reactor. Further converting; And (d) recovering the gaseous ammonia and carbon dioxide-containing product separated in step (b) at a controlled rate that meets the requirements of the requirements, wherein the method for producing ammonia from urea is performed in the hydrolysis reactor. The temperature is not controlled but is varied to meet the demand conditions for ammonia and the pressure is changed as a function of the demand conditions for ammonia or the reactor operating temperature. |
