Chemical process modeling
Encyclopedia
Chemical process modeling is a computer modeling technique used in chemical engineering
process design. It typically involves using purpose-built software to define a system of interconnected components, 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
. Simulations can be as simple as the mixing of two substances in a tank, or as complex as an entire alumina refinery.
Chemical process modeling requires a knowledge of the properties of the chemicals involved in the simulation, as well as the physical properties and characteristics of the components of the system, such as tanks, pumps, pipes, pressure vessels, and so on.

Process Flow diagram
A process flow diagram is a diagram commonly used in engineering to indicate the general flow of plant processes and equipment.The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations...
