ABSTRACT
Today, simulation is an accepted way of studying various processes that are practised in the chemical and biochemical industries, including processes to control air and water pollution. These processes may be a single-unit operation or involve an entire plant. Simulation may be carried out to study the behaviour of these unit operations or the plant as such without fabricating any equipment or the entire plant. Therefore, there is no real loss or damage to the real world (i.e. life, equipment or even the environment). However, simulation studies can be used to predict such losses.
