Abstract
In the field of petrochemical industry, the efficient separation technology is of great significance for improving the production efficiency and product quality. With the increasing global demand for energy, the traditional separation methods have been difficult to meet the efficient demand of modern industry. The purpose of this study is to explore the application of new efficient separation technology in petrochemical industry to improve the separation efficiency and reduce the energy consumption. A variety of advanced separation technologies, including membrane separation, adsorption separation and supercritical fluid extraction, combined with experimental and simulation analysis, were used to systematically evaluate the applicability and effect of these technologies in different petrochemical processes. The experimental results show that the membrane separation technology shows significant advantages in the purification of light oil, and its selectivity and permeability are better than the traditional distillation method; the adsorption separation technology shows high efficiency and high selectivity in the desulfurization process of heavy oil, and the supercritical fluid extraction shows unique advantages in the fine separation of complex mixtures. Through comparative analysis, this study found that these new separation technologies not only significantly improve the purity and yield of products, but also greatly reduce the operating cost and environmental impact. In addition, the research also puts forward optimization strategies and practical application suggestions, which provide scientific basis and practical guidance for the technological innovation in the petrochemical industry. The results of this study not only enrich the theoretical system of efficient separation technology, but also provide new ideas and technical support for practical industrial applications.
