盐酸法钛白粉生产工艺

Production process of titanium dioxide via hydrochloric acid process

盐酸法钛白粉生产工艺主要包括酸解、还原、结晶、萃取、水解、煅烧、破碎及盐酸回收等。该生产工艺具有原料适应性强、能耗低、"三废"排放量少、盐酸可循环利用等优点。氯碱企业利用副产盐酸生产钛白粉,可产生较好的经济效益和社会效益,是值得氯碱企业开发的项目。

The hydrochloric acid process for titanium dioxide production comprised acid hydrolysis, reduction, crystallization, extraction, hydrolysis, calcination, crushing, and hydrochloric acid recovery, etc. The production process has the advantages of good adaptability to raw materials, low energy consumption, less wastes discharge, and recycling of hydrochloric acid. Chlor - alkali enterprises＇ producing titanium dioxide from byproduct hydrochloric acid will give good economic and social benefits. The project is worth developing in chlor- alkali enterprises.
