Chemical industries process raw material or reactants to change into the wanted products using chemical and physical processes. The economy of the process industries depends upon efficient performance of heat and mass transfer operations. A proper understanding of the heat transfer processes helps in energy savings by effective use of heat-exchanger network.
Improving the performance of mass transfer process equipment like distillation and absorption columns results in not only savings in raw materials but improving the product quality. It can be done by proper sequencing of mass transfer operations. Both heat transfer and mass transfer are important in processes such as evaporation and drying.
