Heat Exchangers

WithBéla G. Lipták

The transfer of heat is one of the most important operations in the processing industries. Heat can be transferred between the same phases (liquid to liquid, gas to gas), or the transfer of heat can be accompanied by a phase change on either the process side of the exchanger (condenser, evaporator, reboiler), or on its utility side (steam heater). In addition, the heat source can be the heat of combustion of a fuel. This chapter discusses the control and optimization of each of these systems, although, Chapters 2 & 6 provide additional information on condenser controls, as does Chapter 8 for evaporator controls.
