Titanium equipment is widely utilized in the chemical industry, particularly in the following sectors:

1. Chlor-Alkali Industry

Titanium’s earliest and largest application in the chemical industry is in chlor-alkali production. Titanium equipment and pipelines account for nearly one-quarter of the total mass in chlorine production processes. Key applications include:

Metal anode electrolytic cells,Ion-exchange membrane electrolyzers,Anolyte pumps,Shell-and-tube wet chlorine coolers,Chlorine wastewater dechlorination towers,Chlorine gas cooling and scrubbing towers,Refined brine preheaters,Pumps and valves for vacuum dechlorination.

2. Soda Ash Industry

In soda ash production, titanium is primarily used in:

Crystallization external coolers,Ammonia condensers for distillation column tops,Ammonium chloride mother liquor heaters,Plate heat exchangers,Umbrella plate heat exchangers,Cooling pipes for carbonation towers,CO₂ turbine compressor rotor impellers,Caustic solution pumps.

3. Vacuum Salt Production Industry

Key titanium equipment includes:

Titanium ammonia evaporators,Titanium preheaters,Titanium precoolers,Titanium flanges,Titanium tube sheets,Titanium pump casings,Titanium elbows.

4. Petrochemical Fiber Industry

Titanium equipment is critical in domestic and imported polyester, nylon, and vinylon production facilities. Its use has significantly contributed to:

Stable and safe continuous production,Improved product quality,Extended equipment lifespan (replacing corrosion-prone stainless steel),Reduced downtime and maintenance costs,Enhanced overall economic efficiency.

5. Fine Chemical Industry

In propylene oxide (PO) production, where highly corrosive media (liquid chlorine and propylene) are involved, titanium is the ideal corrosion-resistant material. Carbon steel, aluminum, copper, nickel, and stainless steel fail under such conditions.

6. Inorganic Salt Industry

Chlorates:

Titanium equipment includes electrolytic cells, titanium anodes, reaction generators, and evaporators. Approximately 15 tons of titanium are required per 10,000 tons of sodium chlorate production.

China’s sodium chlorate production capacity exceeds 1 million tons, with an additional 500,000 tons under expansion.

Potassium Salts (e.g., potassium nitrate, potassium carbonate):

Titanium equipment is used in evaporators, preheating tanks, and coolers. Total domestic production capacity for potassium nitrate and carbonate is approximately 600,000 tons.

7. Other Industries

Titanium Dioxide:

Applications: thin-film concentrators, calcination kiln feed pipes, centrifuge distribution discs.

Urea:

Applications: urea synthesis tower linings, ammonia strippers, decomposition tower heaters, methylamine pump valves and springs, high-pressure mixers.

Dyes:

Applications: serpentine heat exchangers, absorption towers, nozzles for purification towers, fans, water-ring vacuum pumps, filters.

Nitric Acid:

Applications: nitric acid evaporators, NOx tail gas preheaters, nitric acid steam preheaters, gas scrubbers, rapid coolers, condensers, turbo blowers, pumps, valves, pipelines.
