A Perspective on Process Integration

Process integration aims at maximizing synergies in a system by using connections between process units and with the energy conversion and waste management systems. This chapter discusses the importance of the process integration approach and its application using optimization techniques to realize the efficient use and conversion of energy and material resources in a process. It presents a generic and concise method for identifying heat recovery options and considers optimal energy conversion integration between industrial processes at different scales with different levels. These methods require adequate and accurate data as well as appropriate indicators to define the resource and energy efficiency of a process to synthesize the optimal process integration. The chapter focuses on the perspectives of mass and energy integration within processes and within plants by optimizing the exchanges and supply of process requirements.
