ChemCAD is an example of a chemical process flowsheet simulation program (application) useful for the design of many Chemical Engineering unit operations and for the design of complete chemical plants. Simulations are set up through its graphical user interface; output can be accessed through the same or through reports generated by the package in MS Word format. Roughly speaking, the simulation package consists of:

1. A library of pre-defined mathematical models of common Chemical Engineering unit operations;
2. A library of chemical species and their associated thermodynamic properties;
3. A simulation framework for assembling the process unit mathematical models into a single simulation problem and computational methods for determining the solution to the complete plant model.
