Titanium has excellent corrosion resistance and mechanical properties, and is widely used in many fields. Especially in chemical applications, titanium can replace stainless steel as a corrosion-resistant material, which is of great significance for extending the service life of equipment, reducing costs, preventing pollution and improving productivity. In recent years, the range of titanium used in China's chemical industry has been expanding, and the amount has increased year by year, and titanium has become one of the main anti-corrosion materials in chemical equipment. As a kind of corrosion-resistant structural material used in chemical equipment, titanium has become an ideal material in chemical equipment.
The main application areas of titanium in the chemical industry
Chlor-alkali industry
Titanium was first used in the chlor-alkali industry in the chemical industry. These include the production of chlorine gas, oxychloride, pesticides, drifting powder, etc., in the production of chlorine, titanium equipment and pipes account for almost a quarter of its total mass volume '. For example, it is used in metal anode electrolyzer, ionic membrane electrolyzer and anode liquid pump, wet chlorine cooler, chlorine wastewater dechlorination tower, chlorine gas cooling scrubber, refined brine preheater, vacuum dechlorination pump and valve, etc.
Soda ash industry
In the production of soda ash, titanium is mainly used in crystallizing external coolers, ammonia condensers at the top of distillation towers, ammonium chloride mother liquid heaters, plate heat exchangers, umbrella plate heat exchangers, carbonization tower cooling tubes, carbon dioxide turbine compressor rotor impeller, lalkali pump and so on.
Precision chemical industry
Propylene oxide plant industrial raw material is a strong corrosive medium. The two main raw materials used in PO production are liquid chlorine and propylene, these strong corrosive media laid the corrosion foundation of PO production equipment pipeline, production under this process conditions, such as carbon steel, Al, Cu, Ni, stainless steel and other metals are unable to resist corrosion, only titanium is the ideal corrosion resistant metal material.
