近日,日本三菱化学公司决定在中国宁波拟建的第二期精对苯二甲酸(PTA)项目中采用最新的环保型PTA新工艺技术。采用这一新技术的第二期PTA项目装置将于2015年投产,生产能力预计达到120万吨/年,是第一期生产能力的2倍。该新工艺采用了三菱人造丝的水处理膜技术以及循环工艺,每生产1吨PTA所消耗的水量少于2吨,而现行工艺的
Recently, Mitsubishi Chemical Corporation of Japan decided to adopt the latest eco-friendly PTA process technology in the second PTA project to be constructed in Ningbo, China. The second PTA project using this new technology will be commissioned in 2015 with an estimated production capacity of 1.2 million tons / year, twice the production capacity of the first phase. The new process uses Mitsubishi rayon water treatment membrane technology and recycling process, each producing 1 ton of PTA consume less than 2 tons of water, while the current process
