Chemicals – Energy – Water (CEW) Nexus for Sustainable Process Design

Rising demand for greener technologies, increasing competition, growing utility complexities, and evolving resource and environmental issues are some of the important factors reshaping chemical industry. For this, Chemicals, energy and water (CEW) nexus concept is introduced. This nexus is a complex interaction, and the production and supply of any resource affects the other two resources. A generalized CEW nexus model is proposed for process design. A cooling water system is illustrated as a case study. We investigated integrated collaborative management policies on CEW nexus. These contribute to the trend of accelerating the decarbonization of industrial production.
