低汞触媒推广缓慢,无汞技术仍是空白我国是《水俣公约》缔约国之一,根据公约条款,缔约国到2020年将禁止生产、进口和出口加汞产品。电石法PVC生产中使用氯化汞作为触媒,是我国汞消耗量最大的行业。履行国际公约的压力下,我国PVC生产结构该如何调整?PVC清洁生产存在哪些困难?为此,记者采访了中石化齐鲁分公司高级技量师傅建英。履约难点在哪?公约将倒逼行业转型升级,当务之急要引导有条件的电石法企业转向乙烯法。电石法PVC产销量
The slow promotion of low-mercury catalyst, mercury-free technology is still blank China is one of the Minamata Convention, under the terms of the Convention, the parties will ban the production, import and export of mercury products by 2020. The use of mercuric chloride as a catalyst in the production of calcium carbide process PVC is the largest mercury consumption in China. Under the pressure of fulfilling the international conventions, how to adjust the PVC production structure in China? What are the difficulties of PVC cleaner production? To this end, the reporter interviewed senior engineer Qijian Ying of Qilu Branch of SINOPEC. Compliance difficulties where? Convention will force the industry restructuring and upgrading, the most urgent task to guide the conditional calcium carbide enterprises to ethylene method. Calcium carbide production and sales of PVC
