Liquefied Natural Gas Storage Tanks | Liquefied Natural Gas Storage Tanks Manufacturer--Huzhou Boiler Factory Co., Ltd.

LNG storage tanks are specialized equipment designed for storing liquefied natural gas.TwoCategorically pressure vessels, on-site inspection by the Technical Supervision Bureau, issuance of pressure vessel inspection certificate, and completion of processes such as external rust removal and painting. The liquefied gas storage tank undergoes strict quality assessment for the material, appearance dimensions, weld quality, operating quality, installation quality, internal equipment, and safety accessories of the pressure components. Widely used in industries such as industrial gases and gas fuels, including units with high gas consumption like machinery, chemicals, metallurgy, etc., it serves as a centralized gas supplyMostHigh-quality equipment. Features include long service life, small footprint, easy operation, and centralized control. The gas leaked from LNG tanks is also very cold, and contact with the skin can cause burns similar to blisters due to low-temperature burns. Natural gas is an asphyxiant. The oxygen content in the atmosphere is about 21%, and when the oxygen content in the air drops below 18%, it can cause asphyxiation in humans.

LNG Storage Tank Operation Procedure:

Wear antistatic suits, shoes, helmets, etc., and place devices prone to static, such as cell phones and computers, in a safe area.

2. Check that the tank's thermometer, level gauge, pressure gauge, flammable gas alarm, and safety valve are functioning properly.

All valves of the tanks to be pressurized are to be confirmed closed, except for the root valve and the emergency shutdown valve.

4. The bottom liquid inlet valve and the pressure boost liquid and vapor valves are open, as well as the valves before and after the pressure booster vaporizer are open.

5. Open the low-temperature cutoff valve before the vaporizer, the ambient temperature flanged ball valve after the vaporizer, and all valves in the pressure regulation system that need to be opened.

6. A single storage tank is sufficient to meet the gas supply requirements when the gas flow rate is less than 1000 Nm3/h up to 2000 Nm3/h.

7. When the tank pressure reaches more than 0.15 MPa above the discharge pressure, slowly open the liquid outlet valve and start supplying gas.

8. The LNG tank must operate with a liquid level not exceeding 90% and not below 15%.

8. The on-duty personnel must frequently inspect the gas supply, monitor the liquid level and pressure changes in the storage tanks, and ensure at least three records are made daily.

9. Regularly inspect the tank, welds, valves, etc., and take timely measures to prevent gas leaks to ensure the LNG meets production requirements.
