In 1993, Taihua Chlor-alkali Branch Company introduced the most advanced ion-exchange membrane caustic soda technology from Japan Asahi Glass at that time and built a domestic advanced 20,000-ton/year ion-exchange membrane caustic soda plant. After technical innovation, the annual production capacity reached 50,000 tons. With the increasing market demand for high-quality caustic soda, Taihua Chlor-Alkali actively digests and absorbs advanced technologies of similar devices at home and abroad. Relying on the comparative advantages of Shanxi's electricity and energy, it also invested RMB 119 million in the rolling technology reform of ion-exchange membrane caustic soda equipment. .
In 2009, the company introduced the world's most advanced Japanese chlorine company's high-energy zero-polarity natural circulation repolarization tank, added four ion membrane electrolyzers, and completed high-low pressure rectification, brine systems, chlorine and hydrogen treatment processes Supporting and perfecting the transformation, so that the production capacity of caustic caustic soda membrane reached 110,000 tons/year. At the same time, the company also completely eliminated 90,000 tons/year diaphragm caustic soda plant, and adopted vacuum dechlorination technology to recover chlorine gas, so that the ion-exchange membrane caustic soda production process can achieve zero discharge of “three wastesâ€, and hydrochloric acid dehydration technology was used to increase chlorine hydrogen as Polyvinyl chloride (PVC) matching basically meets the needs of the 150,000 tons/year PVC unit for chlorine hydrogen.
The chlor-alkali branch of Taihua Chemicals Corporation insists on the use of domestic and foreign advanced technologies to reform the caustic soda process. Recently, the company introduced the 60,000 tons/year ion-exchange membrane caustic soda project of Japan's Nai Chlorine Company.
