How to store six sulfur fluoride gas
Storage of six sulfur fluoride in daily storage should be stored in a cool, ventilated storeroom. Stay away from fire and heat. The temperature should not exceed 50 DEG C. It should be stored separately with the inflammable and oxidizing agent, and avoid the mixed storage. Closed operation and local ventilation. After special training, the operation rules are observed. At the same time, it is recommended to wear a filter type mask (half mask). Avoid contact oxidizing agent. Light and light unloading when handling.
The bottled six sulfur fluoride gas product is high pressure filling gas, which should be used after decompression. The life of the packaged gas cylinder has been used, and the expiration of the gas cylinder must be sent to the Department for safety inspection, so that it can continue to use it. When each bottle of gas is used to the end, the remaining pressure inside the bottle should be kept at 0.5MPa. The minimum value should not be less than 0.25MPa residual pressure. Bottle valve should be closed to ensure gas quality and safety. Bottled gas products in the transport storage and use should be put in non combustible gas and combustion gas stacked together, not close to the fire and heat, not oily wax, not exposure, do not throw, do not hit, no arc or arc in the cylinder body, no rough handling.
At present, there are two main principles of recovery and storage used in the six sulfur recovery purification unit. A cryogenic liquefaction method is used to make the temperature of SF6 gas reach the saturated steam temperature under the pressure at a certain pressure under the pressure of gas recovery. The gas is then liquefied, and then the gas is stored in the form of liquid. The other way is to use high-pressure liquefaction principle, in gas recovery, at that time temperature, use compressor to raise gas pressure until saturated vapor pressure, make SF6 liquefaction as liquid, and store in liquid form.
