1.Chlor-alkali industry
Titanium was the earliest in the chemical industry, and the largest user of titanium is the chlor-alkali industry. These include the production of chlorine, oxychloride, pesticides, drift powder, etc. In the production of chlorine, titanium equipment and pipelines 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, vacuum dechlorination pumps and valves, etc. .
2. Soda ash industry
In soda ash production, titanium materials are mainly used in crystallization external coolers, distillation tower top ammonia condensers, ammonium chloride mother liquor heaters, flat plate heat exchangers, umbrella plate heat exchangers, carbonization tower cooling tubes, and carbon dioxide turbine compressors. Rotor impeller, lye pump, etc.
3. Vacuum salt making industry
Titanium ammonia evaporator, titanium preheater, titanium precooler, titanium flange, titanium tube plate, titanium pump casing and titanium elbow.
4.Petrochemical fiber
At present, petrochemical fiber companies such as polyester, nylon, and vinylon, whether imported from abroad or designed and manufactured domestically, have used some titanium equipment. The application of titanium equipment has played a positive role in the development of my country's chemical fiber production, especially for safe, stable and sustainable production, improving product quality, preventing premature corrosion failure of stainless steel, extending the service life of equipment, reducing parking and maintenance, and improving comprehensive economic benefits. made significant contributions.
5. Fine chemical industry
The industrial raw material for propylene oxide plant is a highly corrosive medium. The two main raw materials used in PO production are liquid chlorine and propylene. These strong corrosive media lay the corrosion foundation for PO production equipment and pipelines. Production under such process conditions, such as carbon steel, Al, Cu, Ni, stainless steel No other metal can resist corrosion, but titanium is the ideal corrosion-resistant metal material.
6. Inorganic salt industry
Inorganic salts mainly include chlorates and potassium salts. Domestic sodium chlorate production has developed rapidly in the past two years, with total production capacity exceeding 1 million tons, and about 500,000 tons are in expansion or preliminary work. Titanium chlorate equipment mainly includes electrolytic cells, titanium anodes, and reaction generators , evaporators, etc., approximately 15t of titanium material is needed for every 10,000 tons of sodium chlorate.
Potassium salt products include potassium chloride, potassium sulfate, potassium nitrate, potassium carbonate, etc. Currently, China's total production capacity of potassium nitrate and potassium carbonate is approximately 600,000 tons. Titanium equipment is required for evaporators, preheating tanks and coolers in the production of potassium nitrate and potassium carbonate.
7. Other industries
Titanium dioxide titanium material is used in thin film concentrators, calcining kiln feed pipes, centrifuge distribution plates, etc.
Urea Titanium materials are used in urea synthesis tower linings, ammonia stripping towers, general decomposition tower heaters, methylamine pump inlets, drain valves and springs, high-pressure mixers, etc.
Dye titanium materials are used in coil heat exchangers, absorption towers, purification tower nozzles, fans, water ring vacuum pumps, filters, etc.
Nitric acid titanium materials are used in nitric acid evaporators, nitrogen oxide tail gas preheaters, nitric acid steam preheaters, gas scrubbers, rapid coolers, condensers, turbine blowers, pumps, valves, pipes, etc.
