Process integration and the second law of thermodynamics: Future possibilities

Charles A. Berg

Energy, 1980, vol. 5, issue 8, 733-742

Abstract: The term “process integration” is used with many meanings. When one uses the second law of thermodynamics to examine processes such as petroleum refining, oxygen production or steelmaking, one often finds that certain of the requirements for fuel can be reduced by the use of a more exacting heat exchange, or by transferring the heat rejected from certain high-temperature steps in the process to stages where lower temperature heat is required, or by combining steam generation with electrical generation, and so forth. This is one sense in which process integration is frequently used. In essence, this use of the term means the economic optimization of the use of energy in processing. The history of such work in engineering is long. Among the lucid and valuable contributions to this aspect of process design, the work of M. Benedict offers an outstanding example from which every engineering student and practicing engineering can profit.
