Natural gas horizontal storage tank factory price Shandong Zhongjie LNG storage tank pressurization work

Description :

LNGlow-temperature storage tankThe main stored material is liquefied natural gas, which is mainly composed of liquid methane. In the process of using liquefied natural gas, it is necessary to gasify the liquid natural gas and send it to the boiler. The discharge of LNG low-temperature storage tanks is powered by the self pressure of the tanks. After the liquid is sent out, the liquid level drops and the gas phase space in the storage tank increases, resulting in a decrease in pressure inside the tank. Therefore, it is necessary to continuously replenish gas into the tank and maintain the pressure inside the tank constant in order to meet the process requirements.

　　And there is an air heated gasifier and a pressure increasing valve on top of the storage tank. The installation height of the air-cooled vaporizer should be lower than the liquid level of the storage tank. When the outlet pressure of the booster valve is lower than the set value, it opens, and when the pressure rises above the set value, it closes.

　　Boosting process: When the pressure inside the tank is lower than the set value of the boosting valve, the boosting valve opens, and the liquid in the tank enters the air heated gasifier by the static pressure of the liquid column. The gas generated by the liquid gasification flows through the boosting valve and the gas phase pipe to supplement the liquid phase space of the storage tank. The continuous replenishment of gas increases the pressure inside the tank, and when the pressure rises above the set value of the booster valve, the booster valve closes. At this point, the pressure inside the pressurized gasifier will prevent the liquid from continuing to flow in, and the pressurization process will end.

　　The above is the basic working principle of LNG low-temperature storage tanks. With the development of natural gas extraction technology, liquefied natural gas will be the first to bear the brunt of the future energy industry. Our company will do our utmost to work together with the natural gas energy industry to help China's energy industry stabilize and achieve long-term success, and to establish the reputation of Made in China!
