OPTIMIZATION IN THERMAL DESIGN OF SURFACE CONDENSER BY CHANGING TUBE MATERIAL

Abstract

Owing to the wide utilization of heat exchangers in industrial processes, their cost minimization is an important target for both designers and users. Traditional design approaches are based on iterative procedures which gradually change design parameters until a satisfying solution, which meets the design specifications, is reached. However, such methods, besides being time consuming, do not guarantee the reach of an economically optimal solution. In this paper a procedure for optimal design of shell and tube heat exchangers is proposed, which utilizes a aspen plus software to minimize the total cost of the equipment including capital investment and the sum of discounted annual energy expenditures related to pumping. With changes of different parameters like thermal conductivity, Heat transfer rate, flow rate, Inlet and outlet of cooling water required for cooling purpose, we can optimise the thermal design by reducing area of surface condenser. Owing to the wide utilization of heat exchangers in industrial processes, their cost minimization is an important target for both designers and users: journal article [1]
