What specific industries or projects does the titanium chemical industry include?

At present, the main application areas of titanium in the chemical industry are:

1. The chlor alkali industry

Titanium was the earliest in the chemical industry, and its users were in the chlor alkali industry. This includes the production of chlorine gas, chlorine oxides, pesticides, floating powders, etc. In the production of chlorine, titanium equipment and pipelines account for almost a quarter of its total mass. Used in metal anode electrolysis tanks, ion membrane electrolysis tanks and anode liquid pumps, tubular wet chlorine coolers, chlorine wastewater dechlorination towers, chlorine gas cooling washing towers, refined brine preheaters, vacuum dechlorination pumps and valves, etc.

2. Soda industry

In the production of soda ash, titanium materials are mainly used for crystallization external coolers, distillation tower top ammonia condensers, ammonium chloride mother liquor heaters, flat plate heat exchangers, umbrella plate heat exchangers, carbonization tower cooling pipes, carbon dioxide turbine compressor rotor impellers, alkali pumps, etc.

3. Vacuum salt industry

Titanium ammonia evaporator, titanium preheater, titanium precooler, titanium flange, titanium tube plate, titanium pump housing and titanium elbow.

4. Petrochemical fiber

At present, both imported from abroad and domestically designed and manufactured petrochemical fiber enterprises such as polyester, nylon, and vinylon have used some titanium equipment. The application of titanium equipment has played a positive role in the development of chemical fiber production in China, especially in safe, stable and sustainable production, improving product quality, preventing premature corrosion and failure of stainless steel, improving equipment service life, reducing parking and maintenance, and improving comprehensive economic benefits, making significant contributions.

5. Fine chemical industry

The industrial raw material for epoxy propane plant is a highly corrosive medium. The two main raw materials used in PO production are liquid chlorine and propylene. These strong corrosive media establish the corrosion foundation of equipment and pipelines in PO production equipment. Under these process conditions, metals such as carbon steel, Al, Cu, Ni, and stainless steel cannot resist corrosion. Only titanium is an ideal corrosion-resistant metal material.

6. Inorganic salt industry

Inorganic salts mainly include chlorates and potassium salts. The production of sodium chlorate in China has developed rapidly in the past two years, with a total production capacity exceeding 1 million tons, and about 500000 tons in expansion or preliminary work. The titanium chlorate equipment mainly includes electrolytic tanks, titanium anodes, reaction generators, evaporators, etc. Approximately 15 tons of titanium material are needed for every 10000 tons of sodium chlorate.

Potassium salt products include potassium chloride, potassium sulfate, potassium nitrate, potassium carbonate, etc. Currently, the total production capacity of potassium nitrate and potassium carbonate in China is about 600000 tons. In the production of potassium nitrate and potassium carbonate, titanium equipment is required for evaporators, preheating tanks, and coolers.

7. Other industries

Titanium dioxide is used for thin film concentrators, calcination kiln feed pipes, centrifugal distribution plates, etc.

Urea titanium material is used for lining urea synthesis towers, ammonia stripping towers, general decomposition tower heaters, inlet and outlet valves and springs of methylamine pumps, high-pressure mixers, etc.

Dye titanium material is used for coil heat exchangers, absorption towers, purification tower nozzles, fans, water ring vacuum pumps, filters, etc.

Titanium nitrate material is used for nitric acid evaporators, nitrogen oxide tail gas preheaters, nitric acid steam preheaters, gas scrubbers, rapid coolers, condensers, turbine blowers, pumps, valves, pipelines, etc.
