Dynamic simulations are able to replicate actual plant behavior, making them valuable for plant design, operation, optimization, and training.

ChemstationsChemical process simulation enables engineers to identify the stable and reproducible operating conditions that help attain acceptable product purities, reaction yields, and cycle times. These simulations give companies and facilities the insight needed to comply with safety and environmental regulations and estimate process economics.

While continuous processes are usually studied with steady-state simulation, batch and semi-batch processes require dynamic simulation. Steady-state simulations can be adapted to predict dynamic behavior by carrying out a series of runs, sensitivity studies, and optimizations, but they do not allow a detailed study of all interactions. Dynamic simulations based on real-time or accelerated-time principles can represent actual plant behavior.

This article reviews the benefits and potential of dynamic process simulation in plant design, operation, optimization, and training.
