由于离子膜法烧碱具有能耗低、质量高和无污染等优点,引起了人们的普遍重视,发展很快。目前世界离子膜法烧碱已占氯碱总量的20％以上。我国从1986年盐锅峡化工厂引进第一套1万t/a离子膜法烧碱生产装置投产起,近10年来,离子膜法在我国氯碱行业有如雨后春笋般发展。到目前为止,已有数十家氯碱企业引进了国外离子膜法烧碱生产装置。而且,其发展势头一直有增无减。 作为90年代的新技术,离子膜的引进对 Because ionic membrane caustic soda has the advantages of low energy consumption, high quality and no pollution, it has attracted people’s attention and has developed rapidly. At present, the world’s ionic membrane caustic soda has accounted for more than 20% of the total chloralkali. China has introduced the first 10,000 t/a ion-exchange membrane caustic soda production plant from 1986 in Yanguoxia Chemical Plant. In the past 10 years, the ion-exchange membrane method has developed in China’s chlor-alkali industry. So far, dozens of chlor-alkali enterprises have introduced foreign ion-exchange membrane caustic soda production facilities. Moreover, its development momentum has been increasing unabated. As a new technology in the 1990s, the introduction of ion membranes
