HEN Design Using Pseudo temperature Approach

This paper, on the basis of multi temperature approach to Heat Exchanger Network (HEM) design, introduced a pseudo temperature approach to design HEM with unequal heat transfer coefficients and direct capital costs of unit heat transfer area. By using the calculation equations of pseudo temperature, with the pseudo temperature approach and MILP transshipment model, the area and cost of HEM can be decreased comparing with those by other approaches.
