Abstract
Membrane separation technology, as an efficient and energy-saving separation method, demonstrates unique advantages in chemical production. Traditional separation methods such as distillation and extraction face issues of high energy consumption and low efficiency. In contrast, membrane separation technology has become a research hotspot due to its characteristics of operating at ambient temperature, low energy consumption, no phase change, simple and compact equipment, and ease of automation. This study aims to explore the application and optimization of membrane separation technology in chemical production, with the ob jective of improving separation efficiency and product quality. By selecting typical chemical processes as research subjects, this study systematically investigates membrane materials, membrane module structures, and operating conditions through a combination of experimental research and theoretical analysis. The results indicate that the use of novel composite membrane materials can significantly enhance separation selectivity, while the optimized membrane module structure effectively reduces concentration polarization phenomena. Reasonable adjustment of operating conditions leads to a stable increase in flux. The innovation lies in developing high-performance membrane materials tailored for specific chemical material systems and establishing a comprehensive optimization model for the membrane separation process, providing theoretical basis and technical support for industrial application. The main contribution is promoting the in-depth development of membrane separation technology in the chemical field, offering new ideas for energy conservation, emission reduction, and green chemical production.
