Modelling of Chemical Process Plant

A chemical plant involves the following basic operations, or stages:(a)raw-material handling and preparation (b)the chemical reaction itself and (c)the separation of the various saleable products from one another and from waste products. In practice, however, the three operations may not take place separately. The rate of a chemical reaction, for instance, may be determined not so much by chemical kinetics as by the mechanical process of mixing the reagents (the reacting components) within the reactor if these are not freely miscible.
