The main application areas of titanium in the chemical industry

1. Chlor-alkali industry

The earliest titanium in the chemical industry, the user is the chlor-alkali industry. These include the production of chlorine gas, oxychloride, pesticides, drift powder, etc., in the production of chlorine, titanium equipment and pipes account for almost a quarter of its total mass'. Such as metal anode electrolyzers, ion membrane electrolyzers and anolyte pumps, tubular wet chlorine coolers, chlorine wastewater dechlorination towers, chlorine cooling scrubbers, refined brine preheaters, pumps and valves for vacuum dechlorination, etc. .

2. Soda ash industry

In the production of soda ash, titanium materials are mainly used in the crystallization external cooler, the ammonia condenser at the top of the distillation column, the ammonium chloride mother liquor heater, the plate heat exchanger, the umbrella plate heat exchanger, the cooling pipe of the carbonization tower, and the carbon dioxide turbine compressor. Rotor impeller, lye pump, etc.

3. Vacuum salt industry

Titanium ammonia evaporator, titanium preheater, titanium precooler, titanium flange, titanium tube sheet, titanium pump casing and titanium elbow.

4. Petrochemical fiber

At present, petrochemical fiber enterprises such as polyester, nylon and vinylon, which are imported from abroad or domestically designed and manufactured by themselves, have used some titanium equipment. The application of titanium equipment has played a positive role in the development of chemical fiber production in my country, especially for safe, stable and continuous production, to improve product quality, to prevent premature corrosion and failure of stainless steel, to improve equipment service life, to reduce downtime and maintenance, and to improve comprehensive economic benefits. made a significant contribution.

5. Fine chemical industry

The industrial raw material of propylene oxide plant is a strong corrosive medium. The two main raw materials used in PO production are liquid chlorine and propylene. These strong corrosive media lay the foundation for corrosion of PO production equipment and pipelines. Production under this process conditions, such as carbon steel, Al, Cu, Ni, stainless steel, etc. No metal can resist corrosion, only titanium is an ideal corrosion-resistant metal material. Grade 3 Pure Titanium Foil

6. Inorganic salt industry

Inorganic salts mainly include chlorate and potassium salts. Domestic sodium chlorate production has developed rapidly in the past two years. The total production capacity has exceeded 1 million tons, and another about 500,000 tons is under expansion or preliminary work. The equipment made of titanium chlorate mainly includes electrolytic cells, titanium anodes, and reaction generators. , evaporator, etc., about 15t of titanium material is needed for every 10,000 t of sodium chlorate.

Potash products include potassium chloride, potassium sulfate, potassium nitrate, potassium carbonate, etc. At present, the total production capacity of potassium nitrate and potassium carbonate in China is about 600,000 tons. Evaporators, preheat tanks and coolers in the production of potassium nitrate and potassium carbonate require titanium equipment.
