Application of Titanium and Titanium Alloy in Chemical Chlor-alkali Industry
Chlor-alkali industry is the raw materials industry, its products are basic chemical raw materials, widely used in light textile, paper making, pesticides, medicine, building materials, metallurgy and so on. Chlor-alkali is one of the key development projects of chemical industry, and it is also a big user of titanium materials.
In the production of chlorine, titanium equipment and pipeline account for almost a quarter of its total mass. For example, it is used in metal anode electrolyzer, ionic membrane electrolyzer and anode liquid pump, tubular chlorine cooler, chlorine wastewater dechlorination tower, chlorine cooling scrubber, refined brine preheater, vacuum dechlorination pump and valve, etc.
Because it has excellent corrosion resistance to wet chlorine and sodium chloride solutions, titanium and titanium alloy materials are widely used in the chlor-alkali industry. In Russian chlorine production, more than 80 percent of equipment and pipes are made of titanium. Titanium seamless tube and titanium welding tube are widely used in fabrication the tube bundle for tubular cooler and so on. Titanium forgings and titanium plates are also the best material for manufacturing chlorine production equipment.
The use of titanium and titanium alloy are expanding day by day, from caustic soda to sodium carbonate and chlorate. urea, ammonium chloride, chemical fertilizer, inorganic salts, organic synthesis, pesticides, fine chemical engineering, etc.
