Abstract
A systematic method for synthesis of heat exchanger networks by using fuzzy approach is presented in this work, the proposed method consists of three sequential steps to select the optimal approach temperature: i) estimation of minimum approach temperature, minimum hot utility and minimum cold utility. ii) Fuzzy approach. iii) selection of the best weight index. The proposed method has been applied for many problems wellknownin published literature. The results of these case studies show that the present strategy is simple and accurate in finding out global optimum in comparison with previous works, characterized by its simplicity and can be implemented by hand calculations. The present study explores new systematic method for synthesis heat brexchanger network. The proposed method when applied to problems previously reported in the literature yielded optimum solutions whichare consistent with different approach. It is evident that the performance of the Fuzzy approach is quite encouraging, characterized by its simplicity and can be implemented by hand calculations.The results of case studies show that the present strategy is both robust and accurate in finding out global optimum cost & optimum minimum approach temperature in comparison with previous works, which ensures its economic effectiveness.
