The article presents a process in urea production that integrates thermodynamic principles and software engineering to produce flowsheeting tools that can be used for modelling the important aspects of urea production. The models were based on the Stamicarbon and Snamprogetti processes which are used in 76% of the world market. The two processes are compared and thermodynamic modeling is discussed. Using modern software technology, a model was implemented which allows it to be used as spreadsheets or operating training software.
