![]() This includes the composition of individual molecular species in the stream the overall mass flowrate the streams pressure and temperature. In the example above the feed stream to the column is defined in terms of its chemical and physical properties. This is essentially an optimization problem which has to be solved in an iterative process. The goal of a process simulation is to find optimal conditions for a process. The software solves the mass and energy balance to find a stable operating point on specified parameters. Process simulation software describes processes in flow diagrams where unit operations are positioned and connected by product or educt streams. Basic prerequisites for the model are chemical and physical properties of pure components and mixtures, of reactions, and of mathematical models which, in combination, allow the calculation of process properties by the software. Process simulation is a model-based representation of chemical, physical, biological, and other technical processes and unit operations in software.
