LNG gasification station storage tank
LNG gasification station storage tank
Vacuum LNG cryogenic liquid storage tank is a commonly used and advanced long-term storage equipment for cryogenic liquids. It has the advantages of large storage capacity, adjustable pressure, low evaporation rate, safety and reliability, etc. It is widely used in LNG filling stations and LNG gasification stations. , LNG emergency peak shaving station and other projects. The storage tank adopts a double-layer cylindrical structure, and the interlayer is filled with insulation material pearl sand and evacuated. It is mainly composed of an inner tank and an outer tank, a thermal insulation structure, a piping system and safety accessories.
Product Details
storage container
The storage tanks produced by our company have different sizes and specifications 5M3-250M3, pressure 0.7MPa-2.16MPa vertical, horizontal, and non-standard. A special low-temperature pressure vessel with a double-layer high-vacuum insulation structure, similar to the structure of a household thermos and the principle of insulation), is mainly used to store and transport liquid industrial gases (LO2, LN2, LAr, LCO2) at a temperature of -196°C;
The cryogenic vessels designed and produced by our company comply with the requirements of GB150-1998 "Steel Pressure Vessels" and GB-18442 "Fixed Vacuum Powder Insulated Cryogenic Liquid Storage Tanks", and accept the National Quality and Technical Inspection Bureau "Pressure Vessel Safety Technical Inspection Regulations" "Supervision has the following functions and features:
Each storage tank has a low temperature experiment before leaving the factory to ensure the 100% pass rate of the equipment and reliable insulation. The low-consumption storage adopts the storage tank's special perlite parameters to meet the requirements and is evacuated. The vacuum degree is ≤2.0Pa, in order to ensure low temperature The interlayer of the storage tank has a long life. The inner tank and the interlayer have undergone strict air pressure, air-tightness experiments and leak detection by helium mass spectrometer. The leakage rate is less than or equal to 1×10-6Pa. The use of safety accessories is more assured.
Double safety valve and double bursting membrane configuration, the number of safety valves is more than other manufacturers, basically every closed pipeline has a safety valve.
The three-way valve design is used in front of the safety device, so there is no need to worry about the safety device being closed, and it is more convenient for the maintenance and replacement of the safety accessories. Minor problems are fully taken into account the needs of users.
The material of the tank liner is made of high-quality stainless steel plate and passivated. It is equipped with an automatic pressurizing tank valve, which can automatically pressurize.
The storage tank can be equipped with gas saving device.
When the pressure of the cryogenic liquid storage tank exceeds the set pressure, the storage tank automatically uses gas to depressurize; when the pressure of the cryogenic liquid storage tank is lower than the set pressure, the storage tank automatically opens the booster device to increase the pressure. In this way, the pressure of the entire cryogenic liquid storage tank is kept at a constant state.
