3. HEAT EXCHANGERS
                 3.1 Classification of heat exchangers


            Transfer  of  heat  from  one  fluid  to  another  is  an  important  operation  for  most  of  the
            chemical industries. The most common application of heat transfer is in designing of


            heat  transfer  equipment  for  exchanging  heat  from  one  fluid  to  another  fluid.  Such
            devices  for  efficient  transfer  of  heat  are  generally  called  Heat  Exchanger.  Heat


            exchangers are normally classified depending on the transfer process occurring in them.

                  General classification of heat exchangers is shown in the Figure 3.1.
