Process Integration and Coupling to Improve the Biorefinery Process

Abstract

Biomass is a naturally renewable resource with wide distribution and huge annual output.  It is the most abundant  renewable organic resource in the world. Biorefinery can be defined as a processing system that converts biomass into a full range of energy products and chemical materials through a series of physical, chemical, and biological conversion treatments. It provides a practical technical route for reducing global dependence on fossil energy, mitigating the greenhouse effect, and promoting the green transformation of the global chemical and energy industry. To fully utilize the components of biomass, the biorefinery process generally comprises complex processing units and procedures, which results in low production efficiency and high investment. Process integration and coupling can effectively streamline its procedures and reduce the number of processing units. This can greatly enhance its production efficiency and reduce investment, thus improving its process economy.  In recent years, a variety of innovative integration and coupling strategies have been developed in the biorefinery process. However, current process integration and coupling still face multiple practical challenges. This editorial will provide a brief discussion on the use of process integration and coupling in the biorefinery process.
