Abstract
Membrane separation technology, as an efficient and energy-saving separation method, demonstrates promising application prospects in chemical processes. This study aims to enhance the separation efficiency and resource utilization in chemical processes by systematically investigating the current applications of membrane separation technology in the chemical industry and proposing optimization strategies. Through the performance analysis of various membrane materials, including polymer membranes, inorganic membranes, and composite membranes, and in conjunction with practical industrial requirements, a comprehensive improvement plan based on membrane structural design and operational parameter optimization was developed. The research adopted a combination of experimental validation and theoretical simulation, focusing on the effects of pressure, temperature, fluid properties, and other factors on membrane separation performance. Key process parameters were optimized using response surface methodology. The results indicate that the optimized membrane separation technology significantly improved the purity and recovery rate of target products while reducing energy consumption and environmental impact. Additionally, this study innovatively introduced intelligent control algorithms for real-time monitoring and dynamic regulation of membrane fouling, effectively extending the service life of membrane modules. This achievement provides crucial references for the large-scale application of membrane separation technology in complex chemical systems and lays a technical foundation for the development of green chemistry. Overall, this study not only deepens the understanding of membrane separation mechanisms but also opens new avenues for the sustainable development of chemical processes..
