     two aspects of the existing minimum rule (mr) are used in the optimization of heat exchange networks (hens). one aspect is to use the minimum of the algebraic quantities ω1 and ω2 or the minimum of cold and hot stream heat capacity flowrates of each heat exchanger (hex) in hen optimization. the other aspect is the dependency (or relationship) between the input and output temperature differentials of each hex in hen. as a consequence of the first aspect, the number of constraints of the hen optimization problems of hen synthesis is reduced. the second aspect is used to reduce the calculations of the hen hexs’ areas. the results obtained are demonstrated using no stream splitting and stream splitting synthesis formulations. in stream splitting formulation, hens are composed of superstructures.
