Do asphalt storage tanks at around 180°C require a vent valve and a nitrogen protection system? Thank you. As for the design of the asphalt tanks that people are currently using, the standards do not provide any clear specifications for this type of CB liquid.
A breathing valve is necessary, with an inlet and an outlet; otherwise, how can the air in the top space of the oil storage tank be replenished? There’s no need to use nitrogen sealing for asphalt tanks, as it’s not toxic.
Regulation Class B doesn’t require the installation of a breathing valve; isn’t it fine for me to just use an exhaust vent?
Vent pipe + flame arrester; an additional pipe opening is provided to install a hydraulic safety valve, to prevent negative pressure from causing collapse due to blockage of the flame arrester
It doesn’t have to be this complicated, right? Just make a vent hole
There is no need for nitrogen protection with a breathing valve
The breather valve was quickly clogged by asphalt fumes, increasing the risk even further
Petrochemical regulations require flame arresters to be installed in Classes A, B, and C A, while vent valves are required for Classes A and B.
Asphalt has high viscosity and low volatility, and requires high storage temperatures along with adequate ventilation; otherwise, due to changes in ambient temperature, there is a risk of water vapor forming at the top of the tank.
If the breather valve is equipped with heating, will it still get clogged?
