Application of FRP in Chlor-alkali Industry
The chlor-alkali industry is an important chemical industry that produces chlorine, hydrogen and sodium hydroxide based on the electrolysis of brine. Its production process involves a large number of highly corrosive media and high humidity and high temperature environments and has extremely high requirements for the corrosion resistance of equipment materials. FRP products are widely used in many links of the chlor-alkali industry due to their superior corrosion resistance, light weight, high strength and long life.
Brine refining section: FRP tanks are used to control the content of Ca2+, Mg2+, Fe3+ ions in crude brine. The lining anti-corrosion layer is made of polyester fiber as a reinforcement material, and the body material is made of low Ca2+, Mg2+ resin.
FRP storage tanks: used to store corrosive media such as brine and dilute acid, with excellent corrosion resistance, safety and environmental protection.
FRP pipelines: used to transport brine and chemical additives, resistant to corrosion by strong acid and strong alkali media, ensuring the stability and reliability of the transportation system.
FRP filters: used in the process of brine purification, resistant to high salt environments, and extend the service life of equipment.
This section involves corrosive media such as sodium chloride solution, wet chlorine, and ammonia. FRP equipment includes chlorine water seal tank, collector, chlorine water storage tank, chlorine scrubber, water mist separator, high-purity hydrochloric acid storage tank, etc.
FRP scrubber: used in the process of chlorine drying and purification, efficiently removes impurity gases, and has outstanding resistance to strong corrosion.
FRP pipeline: used for chlorine transportation to solve the problems of easy corrosion and leakage of traditional metal pipelines.
FRP absorption tower: used for the absorption and reaction process of chlorine and other gases to ensure efficient and stable treatment process.
FRP tank: used to store high-concentration caustic soda solution to avoid failure of metal equipment caused by alkaline corrosion.
FRP pump housing and valve: equipment parts used to transport caustic soda solution, resistant to strong alkaline medium corrosion, to ensure long-term stable operation.
During the reaction between chlorine and alkali, FRP equipment is corrosion-resistant and has a long service life.
Waste gas purification system: FRP purification equipment can effectively capture and treat waste gas in chlor-alkali production, reducing environmental pollution.
FRP cooling tower: In the chlor-alkali production circulating water system, FRP cooling tower has excellent resistance to salt spray corrosion, long service life and low maintenance cost.
