a) NH3 and CO2 in the raw material supply and purification (b) NH3 and CO2 synthesis of urea (c) physical separation and recovery of urea (d) of the urea solution processing, granulation of urea synthesized in four steps. From an engineering point of view of this issue if the graduating undergraduate students on a full and prehensive training process. The main task is to process design. Process design calculations and drawings. Through the design of training, so soon to embark on social relevant work of the graduates of the chemical production process engineering, chemical engineering design and production management plans have a prehensive understanding. Urea plant design
