| Abstract: | This article is a supplement to the newly compiled "Urea Technology" and describes a method for calculation of the ammonium carbamate decomposition rate in the step of thermal decomposition under reduced pressure in the urea process, the overall ammonia evaporation rate and the vapor liquid composition after decomposition. The nomograms provided can be used to calculate the above parameters under the conditions of various decomposition pressures and heating temperatures in the traditional aqueous solution total recycle process. |
