Specific applications of titanium in the chemical industry
Combined with previous research on the corrosion resistance of titanium materials, we can better understand its specific applications.
Take a look at EXPLORE THE CORROSION RESISTANCE OF NIOBIUM, TANTALUM AND TITANIUM
1. Chlor-alkali industry
The earliest use of titanium in the chemical industry can be traced back to its significant application in the chlor-alkali industry. This sector is essential for the production of various vital substances, including chlorine gas, oxychloride, pesticides, and drift powder, among others. In the intricate process of chlorine production, titanium equipment and pipelines play a crucial role, accounting for nearly a quarter of the total mass utilized. Several key components made of titanium include the metal anode electrolyzer, the ionic membrane electrolyzer, and the anolyte pump. Additionally, titanium is employed in the tubular wet chlorine cooler, chlorine wastewater dechlorination tower, chlorine gas cooling scrubber, refined brine preheater, as well as in vacuum dechlorination pumps and valves. The use of titanium in these applications is not only due to its strength and corrosion resistance but also to enhance efficiency and longevity in processes that involve harsh chemical environments. As a result, titanium has become an indispensable material in modern chlor-alkali production methods.
2. Soda ash industry
In the production of soda ash, titanium materials are mainly used in crystallization external coolers, distillation tower overhead ammonia condensers, ammonium chloride mother liquor heaters, flat plate heat exchangers, umbrella plate heat exchangers, carbonization tower cooling pipes, carbon dioxide turbine compressors Rotor impeller, lye pump, etc.
3. Vacuum salt industry
Titanium ammonia evaporator, titanium preheater, titanium precooler, titanium flange, titanium tube sheet, titanium pump shell and titanium elbow.
4. Petroleum chemical fiber
At present, petrochemical fiber enterprises such as polyester, nylon, and vinylon, whether 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 my country’s chemical fiber production. Especially for safe and stable continuous production, for improving product quality, for preventing premature corrosion of stainless steel, improving equipment service life, reducing parking and maintenance, and improving comprehensive economic benefits. made a significant contribution.
5. Fine chemical industry
The industrial raw material of the 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 have laid the foundation for the corrosion of PO production equipment and pipelines. Production under this process condition, such as carbon steel, Al, Cu, Ni, stainless steel Metals such as titanium are unable to resist corrosion, and only titanium is an ideal corrosion-resistant metal material.
6. Inorganic salt industry
Inorganic salts mainly include chlorate and potassium salt. Domestic sodium chlorate production has developed rapidly in the past two years, with a total production capacity exceeding 1 million tons, and about 500,000 tons are in the process of expansion or preliminary work. Titanium chlorate equipment mainly includes electrolytic cells, titanium anodes, and reaction generators , evaporator, etc., about 15t of titanium is needed for every 10,000t of sodium chlorate.
Potassium salt 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. Titanium equipment is required for evaporators, preheating tanks and coolers in the production of potassium nitrate and potassium carbonate.
7. Others
Titanium Dioxide Titanium materials are used in thin film concentrators, calciner feed pipes, centrifuge distribution plates, etc.
Urea Titanium materials are used in the lining of urea synthesis tower, ammonia stripping tower, general decomposition tower heater, methylamine pump inlet, drain valve and spring, high pressure mixer, etc.
Dye Titanium materials are used in coil heat exchangers, absorption towers, nozzles of purification towers, fans, water ring vacuum pumps, filters, etc.
Titanium nitric acid is used in nitric acid evaporators, nitrogen oxide tail gas preheaters, nitric acid steam preheaters, gas scrubbers, rapid coolers, condensers, turbo blowers, pumps, valves, pipes, etc.
