Titanium has good corrosion resistance and is one of the important structural materials in equipment which used under the action of corrosive media such as chemical industry production. The use of titanium instead of stainless steel, nickel-based alloys and other rare metals can effectively reduce operating costs and extend the service life of equipment.

Titanium is of great significance for improving product quality, energy saving and consumption reduction.

In recent years, titanium materials in chemical industry are mainly used in distillation towers, reactors, pressure vessels, heat exchangers, filters, measuring instruments, steam turbine blades, pumps, valves, pipes, chlor-alkali production electrodes, synthetic tower linings and Other acid-resistant equipment linings, etc.

The application of titanium material in the chlor-alkali industry.

Because the chlor-alkali industry uses the method of electrolyzing saturated sodium chloride (NaCl) solution to prepare sodium hydroxide (NaOH), etc., and further produce the process of series of chemical products, it is very important to prevent The corrosion requirements are very high, so the application demand of titanium materials in the chlor-alkali industry is still very large.

At present, in the chlor-alkali industry, the equipment that has been made of titanium materials includes wet chlorine coolers, anode electrolyzers, heating tubes for dechlorination towers, and pumps for vacuum dechlorination.

For example, the process of producing caustic soda by salt electrolysis produces a large amount of high-temperature wet chlorine gas at a temperature of 75~95℃, which seriously pollutes the environment. A wet chlorine gas cooler made of titanium is used instead of graphite cooler, which has achieved good results and some service life. More than 20 years.

Titanium materials have also been widely used in the soda ash industry

Soda ash is one of the most basic chemical raw materials, and its production process is mainly the synthetic alkali method, including the ammonia-soda method and the soda method. Regardless of the process method, ammonia (NH3) and carbon dioxide (CO2) are mostly used as the gas medium, and the liquid medium is mostly a solution with a higher concentration of chloride ions (CI-).

In the past, carbon steel and cast iron materials were mostly used for the main equipment such as carbonization tower tubes, coolers, and crystallization external coolers. The reaction tower corroded severely and leaks often occurred. However, great changes have taken place after the use of titanium materials.
