ChemCAD is a chemical engineering process simulation software package. This program enables the user to design process flowsheet diagrams(PFD), regulate and edit virtually every aspect about it including feed compositions and equipment parameters. More complicated function of this program includes pipe sizing, pricing, establishing crude assays, and formulating control strategies. One will find that the chief advantage in using this program or any other process simulation software is the avoidance of the nuisance of having to perform countless series of tedious and often repeatative calculations. ChemCAD is one of the most economical, user friendly yet high fidelity simulation software tools available in the market today. There are more than 1500 companies across the globe using this highly versatile software since years and benefitting from its use. Batch reactors are used extensively for the manufacture of small volume high value added products increasingly in production facilities intended for multipurpose use. To achieve stable and reproducible operational conditions is increasingly of importance to achieve the required product purity.
