In practice, all chemical process involves production or
absorption of energy in the form of heat. Heat exchanger is
commonly used in a chemical process to transfer heat from
the hot fluid through a solid wall to a cooler fluid. There are
different types of heat exchanger used in the industry but
most of the industry used heat exchanger system [11]. Heat
exchangers are probably the most common types of heat
exchanger applicable for wide range of operating
temperature and pressure. They have larger ration of heat
transfer surface to volume than double pipe heat
exchangers, and they are easy to manufacture in large
variety of sizes and configuration. They can operate at high
pressure, and their construction facilitates disassembly for
periodic maintenance and cleaning. Heat exchanger find
widespread used in refrigeration, power generation, heating
and air-conditioning, chemical process, manufacturing, and
medical application. A heat exchanger in an extension of
the double pipe configuration. Instead of single pipe within
a larger pipe, a heat exchanger consists of bundles of pipes
or tubes enclosed within a cylindrical shell. In the heat
exchanger one fluid flows through a tubes and a second
fluid flows through within the space between the tubes and
the shell.
