Can a breather valve be used in acid water tanks to prevent oil and gas from leaking out?
Thread Content
The initial distillate, regular distillate, and reduced-distillate water from the atmospheric and vacuum distillation unit flow into the acidic water tank. The liquid at the bottom of this tank is pumped to the acidic water treatment facility. Oil often accumulates in the upper part of the acidic water tank due to inadequate separation of the three types of distillates, so it is necessary to periodically drain this oil using an external tank. Currently, the vapor from the top of the tank is released directly into the atmosphere through venting, which does not comply with safety regulations. Could a breather valve be used to solve this problem?
Let me ask you in return: what is the function of a breathing valve? Can a breather valve be used here to solve the problem you have?
It should be sent to a waste gas recovery facility. Places everywhere are carrying out such projects, right?
What I want to do here is make use of the suction function of the breather valve; since the pressure inside the tank must remain constant as water is pumped out, using a breather valve can also prevent a small amount of oil and gas from escaping
It’s a tank with a capacity of 7-8 cubic meters; the amount of oil and gas present is very small, so it’s not worthwhile to recover waste gas from it
Where does the air from the breather valve go? If it’s still released directly into the atmosphere, then it doesn’t really matter whether it’s used or not. So, let’s use a nitrogen sealing device.
