Six domestic enterprises start chlorination titanium dioxide project

Many companies master the chlorination method

At the same time, Xinli Titanium Dioxide also revealed that the new chlorinated titanium dioxide project has launched a new coastal chlorination titanium dioxide project in Lianyungang area, and has completed the feasibility study, program demonstration, preliminary design and other work: from 2014 to 2017, the new chlorinated titanium dioxide project in Lianyungang Add two 80,000 tons/year chlorinated titanium dioxide production lines; from 2018 to 2020, add two more 80,000 tons/year chlorinated titanium dioxide production lines

The sulfuric acid process is in a dilemma

Sun Peng, general manager of Shandong Dongjia Group, a leading titanium dioxide company, said that the chlorination process has achieved technological breakthroughs in the short term, but the progress and effects of other manufacturers are building and completing the actual measurement unit projects to be seen
.

Yunnan Xinli also said that the current chloride process titanium dioxide production line still has a big gap with DuPont
.
At present, the domestic chlorination process titanium dioxide production line is relatively small and the cost is relatively high.
Only Panzhihua Iron and Steel plans a chlorination process production line of 100,000 tons/year
.

Gan Yong highly praises the sulfuric acid titanium dioxide process of a local company in Panzhihua.
The company uses high-quality acid-soluble titanium-rich materials as materials to solve environmental problems
.
In addition, Panzhihua Xinzhong Titanium is leached with hydrochloric acid under pressure, and the mother liquor is divided and recycled to prepare artificial rutile and new acid-soluble titanium-rich materials
.

Many titanium dioxide companies believe that the original competent authority believed that the solid waste treatment of sulfuric acid titanium dioxide would cause greater environmental pollution.
In fact, this solid waste is much smaller than that of chlorinated titanium dioxide
.
In the past few years, sulfuric acid titanium dioxide projects belonged to the restricted development category.
In recent years, it has been loosened.
Now, as long as the environmental protection requirements are met, the energy and water consumption are no longer restricted
