chlorine gas processing vacuum pump

In severe vacuum conditions, the requirements of liquid ring vacuum pump are very strict. Therefore, 2BE series products are specially designed for pumping various gases.

Overview of chlorine use:

① Disinfection (running water is usually disinfected with chlorine gas. 0.002g chlorine gas is introduced into 1L water. The principle of disinfection is that it reacts with water to generate hypochlorite. Its strong oxidation performance kills bacteria in water. The reason why hypochlorite is not directly used for disinfection of tap water is that hypochlorite is easy to decompose and difficult to preserve, with high cost and high toxicity. Chlorine disinfection can make the dissolution, decomposition and synthesis of hypochlorite in water reach a balance, with appropriate concentration and less residual toxicity in water.)

② Preparation of hydrochloric acid

③ It is used in industry to make bleaching powder or bleaching powder concentrate.

④ To produce a variety of pesticides (such as hexachlorocyclohexane)

⑤ Organic solvents such as chloroform and carbon tetrachloride

⑥ Cl 2 can be used to prepare a variety of disinfectants, such as PVC plastics. The disinfectants containing Cl include ClO 2, NaClO, Ca (CLO) 2.

⑦ It is often used to oxidize FeCl ξ to FeCl ₃

⑧ Industrial use for bromine extraction from seawater (CL Е + 2nabr = = br Е + 2nacl)


In this application, chlorine is recovered and compressed. Chlorine is lethal, toxic and extremely corrosive, so special consideration should be given to compressor materials, sealing fluid and system configuration. Low pressure chlorine applications using high concentration sulfuric acid can be treated with standard ductile iron compressors.

In the case of low working temperature and sulfuric acid as sealing fluid, there is almost no risk of corrosion in iron, so it makes cast iron more cost-effective than Hastelloy. Instead, in high-pressure applications, compressor casings made of austenitic stainless steel (316L or hc276 for some applications) are required, with auxiliary equipment attached to the steel to accommodate the appropriate corrosion allowance. Our application experts and engineers are experienced in the design of chlorine compressors and systems, and can configure solutions to meet your process needs.

In many chemical applications, trace water cannot be tolerated in the product. In some applications, alternative sealing liquid can produce technological advantages. Vacuum pumps and compressors can operate with a variety of liquids, including sulfuric acid, benzene, glycol, gasoline, etc. Our experienced team of application engineers can recommend sealing fluid compatible with your process gas.
