Process synthesis is a key design activity which focuses on the generation of alternatives for creating new processes or retrofitting existing ones. It is closely tied to process integration which is a holistic approach to design and operation which focuses on the unity of the process . This article provides a brief overview of process synthesis and integration. The focus is on key concepts, tools, and applications. The discussion is organized over classes of problems. First, the synthesis of energy systems is discussed with emphasis on the thermal pinch analysis for the conservation of heat through the integration of process hot and cold streams. Next, the material recovery pinch diagram is presented as a basis for reducing the use of fresh resources and the discharge of waste materials through reuse and recycle. Then, the field of process network synthesis is briefly reviewed. Moving to reactive systems, the topics of reaction pathways synthesis, attainable reaction regions, and reactor network synthesis are discussed. The chapter concludes with a discussion of the simultaneous process and molecular design.

in Wiley InterScience (www.interscience.wiley.com).A systematic technique is introduced for the synthesis of cost-effective batch water networks with the placement of interception devices. Utilizing the new concept of property integration, a property-based approach is adopted. The water streams (sources) are characterized by a number of key properties, and water-using units (sinks) are bound with property constraints. The problem also considers a number of interception devices that can be used to modify the properties of the streams to optimize the reuse/ recycle of process streams and minimize fresh resources. A source-tank-interceptiontank-sink representation is developed. Storage tanks are used throughout the network to enable mixing, storage, and dispatch of the reused/recycled water streams. The procedure is supported by an optimization formulation whose solution identifies optimal allocation of sources to tanks, interception devices, and sinks. The solution also determines an optimal policy for operating the water network. A case study is solved to illustrate the important aspects of the devised procedure.
