**About Chemical Process Simulation:**

Chemical Process Simulation provides a model-based representation of chemical, physical, biological, and other technical processes and unit operations in software. It requires a strong understanding of chemical and physical properties of pure components and mixtures, reactions, and mathematical models. This allows for the calculation of a process within a computing environment.

Process simulation software uses flow diagrams to represent processes, with unit operations connected by product or educt streams. The software solves mass and energy balances to find a stable operating point, with the ultimate goal of optimizing process conditions.
