Simulation has become an important tool in understanding the process and getting insight. Process simulators such as Aspen (model based) and gPROMS (equation based) are designed to perform process simulations Fluent CFX and STAR-CD are designed to perform CFD simulations while modeFRONTIER is used for parameter estimation and optimization. Any industrial reactor which involves all three phases requires the knowledge of mass transfer reaction VLE and fluid dynamics etc. In this case where complex interactions between these phenomenons exist we need these simulators to perform calculations. Most of the softwares commercially available are designed to perform specific calculations which suits specific purpose. They can either perform process simulation or CFD simulation or do parameter estimation and optimization studies with in their limits. But in reality these can not be separated and no single tool available can perform these calculations. Hence to understand the process well it becomes important to combine these simulators and do the calculations simultaneously. However the combination results in heavy computational load and calculations become slow. Hence it also becomes necessary to evolve new simulation techniques to improve the speed and performance of the simulator and calculation process. This discussion deals first on combining simulators and then on improving the simulation performance.
