Chemical processes, in general, can be regarded as a sequence of a pretreatment step, a reaction step and a separation step, transforming the incoming raw materials (input) into the desired products (output). This transformation requires energy. Besides the desired product, often undesired byproducts or waste products will also be produced. Engineering of chemical processes is more and more carried out in the framework of the minimization of energy consumption and waste disposal. To fulfill the tasks of diminishing energy consumption and minimization of waste, modular, energy...
