介绍高新技术──膜技术在石油化工厂中应用的研究成果。该技术已用于石化基础原料气的分离回收及“三废”治理，且正在向烃分离、化学反应等方向发展。实践证明，膜技术用于石化行业既可节能降耗，又可提高效率，而且操作方便。用于石化工业的膜材料以无机材料为主。膜技术在石油化工中具有广阔的应用前景，但目前的应用还受到膜本身技术问题的限制。
Introducing high-tech ─ ─ membrane technology in petrochemical plants in the application of research results. The technology has been used for the separation and recovery of petrochemical raw material gas and “three wastes” treatment, and is moving to hydrocarbon separation, chemical reactions and other directions. Practice has proved that the membrane technology for the petrochemical industry can save energy, but also improve efficiency, but also easy to operate. Membrane materials used in the petrochemical industry are mainly inorganic materials. Membrane technology in the petrochemical industry has broad application prospects, but the current application is also limited by the membrane itself technical problems.
