The danger of lng filling station operation
Date: Nov 19, 2019
Lng refueling station in the production and operation process, due to the interference of external objective conditions, fluctuations in operating conditions, equipment and equipment failures and personnel operation skills, etc., there will be many safety hazards, to the production operation of the gas station The hazard coming. The most prominent of these are the following:
1.lng low temperature storage tank liquid level operation risk: lng storage tank high liquid level operation, easy to make the tank pressure rise rapidly, resulting in safety valve take-off, lng gas is released a lot, and may cause secondary accidents occur. When the tank is operated at a low liquid level, the pumping of the cryopump may occur, resulting in equipment damage accidents. The filling capacity of the storage tank should meet the requirements of the filling factor, and the storage liquid level should be controlled within the range of 20-90%. The tank should be equipped with a high and low level alarm interlocking device, and the liquid phase outlet pipe of the tank should be equipped with an emergency shut-off valve.
2.lng tanks create the risk of vortexing or tumbling: in the process of lng storage and filling, the "vortex or tumbling" instability phenomenon often occurs, a large amount of gas generated by evaporation, causing pressure in the tank Sudden increase, resulting in a large amount of natural gas venting, causing serious waste, and may even destroy the tank and process system, causing an explosion or fire, which seriously threatens the safety of personnel and property.
3. Due to the environment of lng filling station operation, there are many sources of ignition, such as frequent vehicles, lighters, electromagnetic sparks of mobile phones, frictional sparks of impact, static electricity and lightning strikes, which may become the ignition source of the gas station.
Therefore, in the operation of the LNG refueling station, we must pay more attention to these safety hazards and achieve safe operation and safe operation. The next article will share with you how to avoid the above-mentioned dangerous safety measures during the operation of LNG filling stations.
