What are the advantages of low-temperature storage tanks for liquefied natural growth gas storage

&Natural growth gas liquefaction storage (1) Natural growth gas liquefaction storage adopts a low-temperature and atmospheric pressure storage method, where the natural growth gas is cooled to below -160 ℃ and stored at a saturated vapor pressure close to atmospheric pressure. When natural growth gas changes from a gaseous state to a liquid state, its volume shrinks by about 600 times. Because the use of natural growth gas liquefaction can greatly increase the storage capacity of natural growth gas, natural growth gas liquefaction storage is one of the means used for seasonal peak shaving and accident gas sources. Many countries have built transportation and storage facilities for liquefied natural growth gas. (2) The storage methods for liquefied natural growth gas include ground metal storage tanks, prestressed reinforced concrete storage tanks, underground freeze-thaw pits, and mine gas storage facilities. Metal LNG storage tanks are widely used and can be divided into double top, double wall, and double bottom tanks. Among them, the suspended top storage tank developed on the basis of vacuum insulated double wall metal tanks has a better structure and is currently the most commonly used type. (3) According to relevant foreign data, the economic feasibility of natural growth gas liquefaction storage is that a 150000 m ³ LNG natural growth gas storage tank requires an investment of approximately 227 million yuan, and the entire tank station, including ancillary equipment, requires an investment of approximately 453 million yuan. High pressure storage tank gas storage (1) The geometric volume of the high-pressure storage tank remains fixed and relies on changes in pressure inside the tank to store gas. High pressure storage tanks are divided into cylindrical and spherical shapes. Compared with cylindrical tanks, spherical tanks have the advantages of better stress, less steel consumption, and lower investment, so they are widely used. (2) In recent years, foreign spherical tanks have been developing towards larger sizes, with a diameter of 47.3m and a volume of 55500 m ³. Some cities in our country have also built many large naturally growing balloon tanks, such as Beijing, Tianjin, Shanghai, Chongqing, Xi'an and other cities that have built 3300m ³ to 10000m ³ naturally growing balloon tanks. (3) High pressure spherical tanks are generally suitable for conditions where the pressure of long-distance pipelines entering the city is low (less than 1.6 MPa) and the gas storage peak shaving scale in the city is moderate. For cities with large gas consumption, if all storage capacity is solved by high-pressure spherical tanks, a large number of spherical tanks need to be built, which requires significant investment. &What are the advantages of low-temperature storage tanks? Liquefied natural growth gas storage tank is a type of storage tank used in the industrial field. This low-temperature tank is sometimes referred to as a liquid nitrogen tank. It is a vertical or horizontal double-layer vacuum insulated tank. The inner liner of this tank is made of a special material called austenitic stainless steel. Other external materials related to this low-temperature tank vary from place to place, and different materials can be used to make the outer container material. Some insulation materials are filled in the interlayer between the outer container and the inner container. In this interlayer, we can extract the air to make the interlayer a vacuum. In real life, this is a situation where the interlayer becomes a vacuum. Bian, we use some benefits of low-temperature storage tanks to utilize them. As for low-temperature storage tanks, their benefits are as follows. For such equipment, their equipment is good and convenient. Usually, we can handle it with one or two people. In the process of equipment operation, it usually only takes a few hours to get them ready. For other processes in use, their operation is simple and easy, and because of the simplicity of operation, they can be used safely. As for low-temperature storage tanks, they can be suitable for various large and medium-sized manufacturers to use. When selecting the type of low-temperature storage tank, we can choose low-temperature storage tanks with different capacities according to different needs. In the operation process of low-temperature storage tanks, the cost of their operation is usually relatively low, and their energy consumption is relatively small. In the process of use, their maintenance costs are very low. In the process of operation, there are also very few personnel needed. Usually, only one person is needed to operate, which can save a lot of expenses. The quality of other low-temperature storage tanks is good and stable, and they can produce high-purity gas. In the process of operation, other low-temperature storage tanks are noiseless and pollution-free.
