Industrial urea granulation is mainly performed in fluidized-bed granulators combined with coolers, crushers and screens to constitute granulation circuits. Unfortunately, this process is usually operated by trial and error with undesired plant shutdowns and far from the optimum capacity. In this context, it becomes critical the design and control of granulation circuits under an integrated approach.In this context, a simulator for the UFT fluidized-bed granulation technology is presented, which consists of ad-hoc models for the units involved [1]. These models were integrated in the gPROMS® environment and can be easily adapted to particular plant configurations by simply ?drag-and-drop? of the necessary units from the established model libraries and connect them to simulate a specific integrated process. Each unit presents a dialog box for the user to set the corresponding design and process variables and parameters.
