What specific industries or projects does the titanium chemical industry include?
At present, the only application areas of titanium in the chemical industry are:
Chlor-alkali industry
Titanium was first used in the chemical industry by the chlor-alkali industry. These include the production of chlorine, chlorine oxides, pesticides, bleaching powder, etc. In the production of chlorine, titanium equipment and pipelines account for almost a quarter of the total mass'. Such as those used in metal anode electrolyzers, ion membrane electrolyzers, anode liquid pumps, shell and tube wet chlorine coolers, chlorine wastewater dechlorination towers, chlorine gas cooling and washing towers, refined brine preheaters, vacuum dechlorination pumps and valves, etc.
Soda ash industry
In the production of soda ash, titanium is 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 pipes, carbon dioxide turbine compressor rotor impellers, alkali liquid pumps, etc.
Vacuum salt-making industry
Titanium ammonia evaporator, titanium preheater, titanium precooler, titanium flange, titanium tube sheet, titanium pump shell, and titanium elbow.
Petrochemical fiber
At present, some titanium equipment has been used by petrochemical fiber enterprises such as polyester, nylon, and vinylon, whether imported from abroad or designed and manufactured domestically. The application of titanium equipment has played a positive role in the development of my country's chemical fiber production, especially in safe, stable, and continuous production, improving product quality, preventing premature corrosion and failure of stainless steel, increasing equipment service life, reducing shutdowns and maintenance, and improving comprehensive economic benefits.
Fine chemical industry
The industrial raw materials of propylene oxide plants are highly corrosive media. The two main raw materials used in PO production are liquid chlorine and propylene. These highly corrosive media lay the foundation for the corrosion of the equipment and pipelines of the PO production unit. Under such 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.
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 another approximately 500,000 tons under expansion or in the early stages of production. Chlorate titanium equipment mainly includes electrolytic cells, titanium anodes, reaction generators, evaporators, etc. About 15 tons of titanium are required for every 10,000 tons of sodium chlorate.
Potassium salt products include potassium chloride, potassium sulfate, potassium nitrate, potassium carbonate, etc. At present, China's total production capacity of potassium nitrate and potassium carbonate is about 600,000 tons. Evaporators, preheating tanks, and coolers in the production of potassium nitrate and potassium carbonate require the use of titanium equipment.
