Process Simulation

Definition

Process simulation is a computational technique used to model and analyze chemical processes, allowing engineers to predict the behavior and performance of these processes under various conditions. This method helps in understanding complex interactions within chemical systems, optimizing operations, and designing new processes efficiently. By creating virtual representations of real-world processes, engineers can experiment with different scenarios without the risk or cost associated with physical trials.
