After purification treatment (removal of CO2, sulfide, heavy hydrocarbons, water and other impurities), natural gas is cryogenically cooled to -162°C under normal pressure and changes from a gaseous state to a liquid state, which is called liquefied natural gas. In this article, I will introduce some knowledge of LNG dispensers, I hope it will be helpful to you.
Operating procedures for LNG dispensers.
The company's LNG dispenser products.
1. After an LNG dispenser tanker enters the station, guide and supervise it to park according to the designated unloading space, connect the grounding wire and pad the anti-slipping wooden block.
2. Check the tanker liquid and storage tank liquid temperature of the LNG dispenser to determine the unloading plan. When the liquid temperature of the storage tank is higher than that of the tanker, the top liquid inlet should be adopted, otherwise the bottom liquid inlet should be adopted.
3. LNG dispenser liquid and gas phase unloading hoses in good condition
4. Check the pressure and liquid level in the storage tank in the storage tank area of the LNG dispenser
5. After the above six points are correct, the operator in the station checks the pressure, temperature and liquid level of the LNG dispenser tanker and records them
6. The operation from the unloading area to the tank area is carried out by the operator in the station from the tanker to the unloading platform by the tanker escort. During the filling process of the LNG dispenser, inspect all process valves, pipelines, and instrument working conditions, make records, and pay attention to avoid danger
7. Specific unloading operations
① Pressurize the LNG dispenser tanker, increase the tanker pressure to the tank pressure plus 0.2MPa, and the tanker pressure does not exceed 0.66MPa.
② Observe the pressure and liquid level changes of the LNG dispenser tanker and storage tank. Through the decompression of the storage tank and the booster operation of the tanker, the pressure difference is maintained at about 0.2MPa, and the tanker pressure does not exceed 0.66MPa.
③ After unloading the liquefied natural gas from the LNG dispenser, close the liquid phase pipe inlet valve and the storage tank inlet shut-off valve.
Jiangyin Furen High-Tech Company was established in 2001. We are the only designated partner of Sinopec. We established a joint venture with Sanhe to introduce advanced Japanese technology.
Our main products include fuel dispensers, LNG/CNG gas dispensers, fuel tanks, car washers, etc. The gas distributors are mainly hydrogen distributors and LNG dispensers. For example, Distribute Gas Self-help LNG Filling with Stand LNG Gas Dispenser, Vehicle Refuelling Self-help LNG Filling Transfer Natural Gas LNG Gas Dispenser, Stainless Steel Bus LNG Filling Explosion-proof LNG Gas Dispenser and many other types of LNG dispensers.
