What is a methyl chloride compressor?

The methyl chloride compressor is a special gas pressurizing equipment customized for methyl chloride medium, which is mainly used in silicone, pesticide and fine chemical production lines to pressurize, condense, liquefy and recycle gaseous methyl chloride. Ordinary air compressors and general compressors cannot be directly used.

Core special requirements include

Supporting materials with strong corrosion resistance: methyl chloride will generate hydrochloric acid when it meets water vapor, which is extremely corrosive. The cylinder block, valve group, pipeline and seal are all made of corrosion-resistant materials such as 316L stainless steel and fluoroplastics, and ordinary carbon steel and corrosive metals are prohibited.

Tight leakage prevention+toxic gas monitoring: methyl chloride is toxic, volatile and anesthetic, sealed with multi-layer composite packing/metal diaphragm, and equipped with toxic and combustible gas detection and alarm device to prevent media leakage from endangering people and the environment.

The explosion-proof grade of the whole machine is up to standard: methyl chloride belongs to flammable and explosive organic medium, and the explosion-proof motor and explosion-proof electric control cabinet of the whole machine meet the Ex d IIC explosion-proof standard and eliminate the ignition source.

Strictly isolate water and prevent acid corrosion: the system is equipped with drying, liquid separation and buffering devices to strictly control the water content of inlet air to avoid hydrochloric acid generated by hydrolysis from corroding the internal parts of the unit.

Special compatible seal and lubricating oil: ordinary oil and rubber will be swollen and dissolved by methyl chloride, so special lubricating oil and fluororubber seal must be selected to prevent sealing failure and oil deterioration from polluting the medium.

Protection against liquid impact: methyl chloride is easy to liquefy under pressure, and the front end is equipped with a gas-liquid separation tank to prevent liquid methyl chloride from entering the cylinder and damaging the valve plate and piston due to liquid impact.

Nitrogen replacement safety interface: nitrogen can be introduced to replace the air in the pipeline before the start-up and maintenance to avoid the mixture of methyl chloride and air to form explosive mixture.

Generally speaking, methyl chloride compressor is a special pressurization equipment for fine chemical industry and silicone industry, which is used for methyl chloride pressurization cycle; The core requirements are hydrochloric acid corrosion resistance, explosion-proof, leakage prevention, moisture control, and supporting special sealing oil resistant to halogenated hydrocarbons to avoid the risks of corrosion, poisoning and explosion.
