Abstract
Desalination is the thermodynamic process of separating fresh water from water that contains dissolved salts. This chapter introduces the concepts and methods required for thermodynamic analysis of desalination systems. Thermodynamic laws are summarized along with the chemical thermodynamics of electrolytes. Exergy analysis is introduced. The work and heat of separation are dened, and the roles of entropy generation and exergy destruction are identied. Important sources of entropy generation are discussed. Examples are given for the application of these methods to several representative desalination systems.
