CHAPTER NINE – Combining Heat Integration with Mass Integration: Synthesis of Combined Heat and Reactive Mass-Exchange Networks

The chapter presents the problem of synthesizing combined heat and reactive mass-exchange networks (CHARMEN) and illustrates its incorporation in a heat-mass integration framework. The basic principles of synthesizing heat-exchange networks "HENs" are also reviewed in the chapter. Numerous methods have been developed for the synthesis of HENs. One of the key advances in synthesizing HENs is the identification of minimum utility targets ahead of designing the network. Several methods of determining minimum-utility targets – such as pinch diagram, algebraic cascade diagram, mathematical programming (optimization) – are also described in the chapter. Mass-exchange equilibrium relations are dependent upon temperature and the selection of optimal mass-exchange temperatures is an important element of design for the synthesis of CHARMEN.
