Application of TA10 equipment in the chemical industry

Thread Content

In chemical production, corrosion of chemical equipment is a major problem. Due to corrosion, a huge amount of steel is wasted each year (2731, 85.00, 3.21%). In our country, corrosion is also the main cause of equipment damage in the chemical industry. As a result, the service life of many devices is only 1-2 years, with the shortest being as little as 1-2 months. The TA10 device exhibits exceptionally excellent performance in terms of corrosion resistance, wear resistance, and erosion resistance. Although titanium equipment requires a high initial investment, its service life is several times to dozens of times longer than that of carbon steel, stainless steel, and cast iron equipment. Due to its outstanding advantages such as low density, high strength, and excellent corrosion resistance, titanium has become highly popular for solving the severe corrosion problems associated with equipment in chemical production, thereby bringing about a significant advancement in anti-corrosion technologies in the chemical industry. The chemical industry is the industrial sector in China’s civilian industry where titanium was first used and where its consumption is the highest. In the past 10 years, the amount of titanium used in China’s chemical industry is equivalent to the total production of titanium in 2009 and 2010 combined. The table shows the proportion of titanium used in various sectors of China’s chemical industry. TA10 equipment is utilized in the chemical industry; currently, the main areas where titanium is applied in this industry are as follows: 1. The chlor-alkali industry – Titanium’s earliest and largest user in the chemical industry is the chlor-alkali industry. This includes the production of chlorine, chlorinated oxides, pesticides, and bleaching powder; in the production of chlorine, titanium equipment and pipes account for almost one-quarter of its total mass. Such as those used in metal anode electrolyzers, ion membrane electrolyzers and anolyte pumps, tubular wet chlorine coolers, chlorine wastewater dechlorination towers, chlorine gas cooling and washing towers, refined brine preheaters, pumps and valves for vacuum dechlorination, etc. 2. In the soda ash industry, titanium materials are primarily used in crystal external coolers, ammonia condensers at the top of distillation towers, heaters for ammonium chloride mother liquor, plate heat exchangers, umbrella plate heat exchangers, cooling tubes in carbonization towers, rotor blades of carbon dioxide turbine compressors, and alkali solution pumps. 3. Titanium ammonia evaporators, titanium preheaters, titanium precoolers, titanium flanges, titanium tube sheets, pump casings made of titanium, and titanium elbows for the vacuum salt production industry. 4. In the petrochemical fiber industry, whether it is polyester, nylon, vinylon and other petrochemical fibers imported from abroad or those designed and manufactured domestically, some titanium-based equipment has already been used. The use of titanium equipment has played a positive role in the development of China’s fiber production industry. It has made significant contributions to ensuring safe, stable, and continuous production, improving product quality, preventing premature corrosion and failure of stainless steel, extending the service life of equipment, reducing downtime for maintenance, and enhancing overall economic efficiency. 5. The industrial raw materials for propylene oxide plants in the fine chemicals industry are highly corrosive substances. The two main raw materials used in PO production are liquid chlorine and propylene; these highly corrosive substances contribute to the corrosion of the equipment and pipelines in PO production facilities. Under such processing conditions, metals such as carbon steel, Al, Cu, Ni, and stainless steel cannot resist corrosion, with titanium being the most suitable metal material for resisting corrosion. 6. The inorganic salts industry includes mainly chlorates and potassium salts. The production of sodium chlorate in China has developed rapidly over the past two years, with the total production capacity exceeding 1 million tons; another approximately 500,000 tons are under expansion or in the preliminary stages of development. Titanium-based equipment for chlorate production includes electrolyzers, titanium anodes, reaction reactors, evaporators, etc. Roughly 15 tons of titanium are required per 10,000 tons of sodium chlorate produced. Potassium salt products include potassium chloride, potassium sulfate, potassium nitrate, potassium carbonate, etc. At present, China’s total production capacity for potassium nitrate and potassium carbonate is around 600,000 tons. In the evaporation units, preheating tanks, and coolers used in the production of potassium nitrate and potassium carbonate require titanium-based equipment. 7. In other industries, titanium dioxide and titanium products are used in film concentrators, feed pipes for calcination kilns, centrifuge distribution plates, etc. Urea: Titanium materials are used for the lining of urea synthesis towers, ammonia stripping towers, heaters in general decomposition towers, the inlet and outlet valves as well as springs of methamine pumps, high-pressure mixers, etc. Dyes and titanium materials are used in coil heat exchangers, absorbers, nozzles in purification towers, fans, water ring vacuum pumps, filters, and more. Titanium materials used in nitric acid are employed in nitric acid evaporators, nitrogen oxide exhaust preheaters, nitric acid steam preheaters, gas scrubbers, rapid coolers, condensers, turbo blowers, pumps, valves, pipes, and more.
