Chemical process modeling is a computer modeling technique used in chemical engineeringprocess design. It typically involves using purpose-built software to define a system of interconnected components,^[1] which are then solved so that the steady-state or dynamic behavior of the system can be predicted. The system components and connections are represented as a process flow diagram.^[1] Simulations can be as simple as the mixing of two substances in a tank, or as complex as an entire alumina refinery.^[2]

Chemical process modeling requires a knowledge of the properties of the chemicals involved in the simulation,^[1] as well as the physical properties and characteristics of the components of the system, such as tanks, pumps, pipes, pressure vessels, and so on.
