In the initial steps of grass-root projects, heat exchangers cost estimation for proper decision
making regarding network optimization design through pinch technology is very important. It
is necessary to forecast the cost of a heat exchanger through cost estimation equations. In
this article, the cost estimation equations of heat exchanger and the heat exchangers
network for shell and tube heat exchangers and plate and frame heat exchangers are
obtained. These equations are the function of heat transfer area by available prices in Iran …
