一、前言我国自行设计的年产万吨维尼纶厂(通用设计)系根据日本引进的北京有机化工厂和北京维尼纶厂生产实践进行的。醋酸乙烯聚合是维尼纶生产中需要严格控制的关键生产过程,通用设计采用在常压下甲醇沸点 I. Preface China’s own designed annual output of 10,000 tons of vinylon plant (Universal Design) is based on the introduction of Japan’s Beijing Organic Chemical Plant and Beijing Vinylon plant production practices. Vinyl acetate polymerization is the production of vinylon need to strictly control the key production process, the common design used at atmospheric pressure methanol boiling point
