This paper presents a heuristic procedure for the synthesis of integrated mass (such as water, gas and solvent) and thermal energy networks. The procedure is based on process integration techniques and looks at design of networks that exhibit minimum mass and energy consumption. This method begins with the application of mass integration with interception (which have overlooked in previous work) followed by heat integration to target and design a network with minimum usage of fresh mass and heat utility. The introduced method involves solving a three way trade - off between energy, fresh sources and interception costs. A case study from the literature is used to show the application of the procedure. The new method resulted in significant savings in the fresh utilities.
