In chemical production, corrosion of chemical equipment is a major problem. Due to corrosion, a huge amount of steel (2731, 85.00, 3.21%) is wasted every year. In our country, the main cause of equipment damage in the chemical industry is also due to corrosion. Therefore, the service life of many equipment is only 1-2 years, and the shortest is only 1-2 months. Titanium equipment has extremely excellent performance in terms of corrosion resistance, wear resistance and erosion resistance. Although titanium equipment has a high one-time investment, its service life is several times, tens of times, that of carbon steel, stainless steel and cast iron equipment. Because titanium has the outstanding advantages of low density, high strength, and good corrosion resistance, it has successfully solved the serious corrosion problem of equipment in chemical production and has been favored. It has brought a leap in anti-corrosion technology in the chemical industry.

Shandong Bojing Chemical Machinery Co., Ltd. was established in 2007. It is a professional manufacturer in the field of fine chemical equipment. The company's products are mainly stainless steel, titanium, nickel, Monel and other non-ferrous materials. It is an integrated design, research and development, and manufacturing. Sexual high-tech enterprises. The core products are widely used in the treatment of waste water and waste gas in biochemical and fine chemical plants, as well as for energy conservation and efficiency enhancement. The company has pressure vessel (level D) manufacturing qualification and ASME certification issued by the General Administration of Quality Supervision, Inspection and Quarantine.

  The chemical system is the first industrial sector that uses titanium in China's civil industry and uses the largest amount. In the past 10 years, the amount of titanium used in my country's chemical industry is equivalent to the sum of the two years of titanium production in 2009 and 2010.

  The application of titanium in the chemical industry

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

   1. Chlor-alkali industry

  The earliest and largest user of titanium in the chemical industry is the chlor-alkali industry. Including the production of chlorine, oxychloride, pesticides, bleaching 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-exchange 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 the production of soda ash, titanium materials are mainly used for crystallization external coolers, distillation tower top ammonia condensers, ammonium chloride mother liquor heaters, plate heat exchangers, umbrella plate heat exchangers, carbonization tower cooling tubes, carbon dioxide turbine compressors Rotor impeller, lye pump, etc.

  3. Vacuum salt industry

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

   4. Petroleum chemical fiber

   At present, no matter whether it is imported from abroad or domestically designed and manufactured by domestic petrochemical fiber enterprises such as polyester, nylon, vinylon, etc., some titanium equipment has been used. 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 and failure of stainless steel, improving equipment life, reducing parking and maintenance, and improving comprehensive economic benefits. Made a significant contribution.

   5. Fine chemical industry

   The industrial raw material of 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 equipment. Under this process conditions, such as carbon steel, Al, Cu, Ni, and stainless steel Other metals cannot resist corrosion, and only titanium is an ideal corrosion-resistant metal material.

   6. Inorganic salt industry

  Inorganic salts mainly include chlorate and potassium salt. The domestic production of sodium chlorate has developed rapidly in the past two years. The total production capacity has exceeded 1 million tons, and about 500,000 tons are in expansion or preliminary work. The chlorate titanium equipment mainly includes electrolyzers, titanium anodes, and reaction generators. , Evaporator, etc., about 15t of titanium material 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. In the production of potassium nitrate and potassium carbonate, the evaporator, preheating tank and cooler need to use titanium equipment.


  7. Other industries

  Titanium Dioxide Titanium is used in thin film concentrators, calcining kiln feed pipes, centrifuge distribution plates, etc.

   Urea Titanium material is used for urea synthesis tower lining, ammonia stripping tower, general decomposition tower heater, methylamine pump inlet, drain valve and spring, high pressure mixer, etc.

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

  Nitric acid Titanium is used in nitric acid evaporator, nitrogen oxide exhaust gas preheater, nitric acid steam preheater, gas scrubber, rapid cooler, condenser, turbo blower, pump, valve, pipeline, etc.
