Mass and Energy Conversion in Processes of Chemical Engineering . Being the practice of chemical engineering, chemical industry is among the industrial branches with a high energy consumption. This is scientifically based on the unity of mass and energy conversion. Although theoretically well‐known these interconnections have only little influence on engineering investigations. That's why incomplete and untrue evaluations of the energetic conditions of chemical processes can occur. After a brief historical survey, a classification of the different kinds of energy for chemical processes will be proposed as a help in solving this problem. This classification facilitates a deeper understanding of the energetics of chemical processes. To increase these investigations the term cumulative exergy expenses can be used for the evaluation of chemical processes. This evaluation considers both the conversion of energy and the conversion of mass. These connections are discussed by one example. If these research purposes are generalised for strategic development, they will lead to a new generation of chemical and energetical plants.
