Technical Requirements
- With high safety and sealing, it can ensure the safety of storage and prevent accidents, widely used in petrochemical and other fields.
- We design our cryogenic liquid flat-bottom storage tanks with double- wall steel structures using high tech insulating materials (perlite + elastic felt + cellular glass insulation block + glass wool).
- The following are safety measures to prevent overpressure:
1) Recycle the evaporated gas from the tank via the BOG pipe;
2) Discharge the gas from the tank to a low-pressure flare through the vent line;
3) The exhalation relief valve actuates to vent gas from the tank to the low-pressure flare;
- The tank is equipped with 2 servo level gauges and 2 radar level gauges to continuously measure the liquid level in the tank.
- The design, installation and replacement of the level gauge will not affect the operation of the tank, and a full-bore ball valve is used to connect it to the tank, preventing liquid overflow due to excessively high liquid levels, or starting the pump or compressor when the liquid level is too low will cause the tank to empty.
