To popularize the status quo of my country regarding large atmospheric LNG storage tanks

　　Development status of large atmospheric LNG storage tanks

　　Large-scale natural gas storage can use two methods, underground gas storage and LNG. The data shows that my country’s current situation is that there are many small pressure storage tanks and few large atmospheric pressure storage tanks.

　　Underground LNG storage tank

　　The inner wall and insulation layer of the underground LNG storage tank are basically the same as the ground storage tank. The insulation layer is made of pearlite and rigid polyurethane foam. The outer tank generally uses reinforced concrete walls and prestressed concrete walls, with a carbon steel dome above and below the dome The aluminum ceiling with glass fiber carpet cold insulation layer has the characteristics of not easy to overflow the storage liquid, strong seismic performance, and high durability.

　　Japan is a country with relatively advanced construction technology for underground LNG storage tanks in the world. Due to lack of natural gas resources, it is a major LNG importer with nearly 20 storage tanks in operation. Tokyo Gas Co., Ltd. is a newly built LNG base in Yokohama, using gas suspension technology. , Air support technology has achieved good results. At present, Japan has built an underground LNG storage tank of 250,000 cubic meters, which has reached the world's advanced level. my country has no corresponding research results in this field.

　　Ground LNG metal concrete tank

　　According to the inner wall material of the ground LNG metal concrete tank, it is usually divided into two types: prestressed concrete tank and membrane tank. Ordinary large-scale storage tanks use prestressed concrete type. The shell material is mainly prestressed concrete, and the inner cylinder is made of low-temperature metal material. There are two kinds of materials for the inner cylinder of the type storage tank: brown steel and stainless steel.

　　In addition, LNG exporting countries such as Indonesia, Brunei, and Algeria, and LNG importing countries such as the United Kingdom and France have built a large number of large atmospheric LNG cryogenic storage tanks, and Korea Natural Gas Corporation has built the world's first large 270,000 m3 LNG storage tank. , my country's LNG storage tanks are mostly small and medium-sized pressure storage tanks. At present, my country has the ability to independently design and build large-scale LNG cryogenic and atmospheric storage tanks.

　　As for the status quo of my country's large atmospheric LNG storage tanks, everyone should have an eyebrow. I will introduce it here today. If you need large atmospheric LNG storage tanks, you can contact our company!
