目前,世界上氯乙烯的生产技术主要有三种:乙炔法、乙烯法和乙烷法。乙炔法是最早工业化的氯乙烯生产技术,此法优点是流程简单,转化率高,但缺点是耗电量较大,尤其其中使用含汞催化剂严重危害工人健康,并造成严重的环境污染。随着生产工艺的发展,在发达国家乙炔法已经被乙烯法路线所取代。但是,我国是一个“多煤、少气、贫油”的国家,我国的乙烯产出基本上完全依赖于石油。自1993年起,我国从石油净出口国变为进
At present, there are mainly three kinds of vinyl chloride production technologies in the world: acetylene method, ethylene method and ethane method. Acetylene process is the earliest industrial production technology of vinyl chloride, this method has the advantages of simple process, high conversion rate, but the disadvantage is the larger power consumption, especially where the use of mercury-containing catalysts seriously endanger the health of workers and cause serious environmental pollution. With the development of production technology, the acetylene process has been replaced by ethylene process in developed countries. However, our country is a country with “more coal, less gas and less oil.” The output of ethylene in our country is basically totally dependent on oil. Since 1993, our country has been transformed from a net exporter of oil
