ABSTRACT
B. Decomposition Section NH 3, C02, and water in the urea synthesis solution are further decomposed and separated through the stepwise decomposers and absorbed and condensed in the respective absorbers operated at 18 and 2 kg/cmla, respectively. The urea solution with 80 wt % of urea concentration is concentrated up to 99.7 wt % for urea prill production or 98.5 wt % for urea granule production in the concentration section.
