Abstract
Chemical process intensification technology, as a critical approach to enhancing production efficiency, reducing energy consumption, and minimizing environmental impact in the chemical industry, has garnered significant attention in recent years. This study aims to investigate novel chemical process intensification technologies and their application effects by systematically analyzing the limitations of traditional chemical processes and proposing advanced intensification solutions based on microreactors, hypergravity fields, and multiphase flow concepts. Combining theoretical analysis with experimental validation, a multiscale model encompassing mass transfer, heat transfer, and reaction kinetics was developed, and systematic performance tests were conducted at the laboratory scale. The results indicate that the use of microstructured equipment can significantly increase the mass transfer coefficient by 3 to 5 times, with improvements in reaction selectivity and yield by 15% and 20%, respectively, while achieving approximately 30% lower energy consumption. Innovatively applying hypergravity technology to gas-liquid two-phase systems successfully addressed the common issue of inadequate mixing in traditional stirred tank reactors, resulting in more efficient mass transfer. Furthermore, through comprehensive optimization design of typical chemical processes, an integrated intensification scheme suitable for large-scale industrial production was proposed, offering new ideas and technical support for achieving green and sustainable development. This research not only enriches the theoretical fr amework of chemical process intensification but also provides essential references for practical engineering applications, demonstrating significant academic value and broad application prospects.
