Why did Fushun Natural Gas Company's gas storage station deflate late at night?

There are two main reasons for late-night deflation in Fushun Natural Gas Company's gas storage station. First of all, natural gas will produce a certain amount of impurities and liquid substances during storage. If these impurities are not discharged in time, it will affect the quality of natural gas and even damage gas storage equipment. Bleeding at night can avoid the peak period of gas consumption during the day and ensure the quality and safety of natural gas. Secondly, because natural gas belongs to combustible gas, if there is an emergency such as leakage inside the gas storage station, venting at night can reduce the loss of people and property. This is because there are fewer people and vehicles around when deflation occurs in the middle of the night. Once an accident occurs, it is difficult to handle and has strong controllability. To sum up, the late-night deflation of Fushun Natural Gas Company's gas storage station is to ensure the quality and safety of natural gas and reduce the loss of personnel and property.
