The oil discharge from the oil tank starts automatically, creating a negative pressure inside the tank; how can air backflow be prevented?
Thread Content
The sewage pumps and sludge oil pumps in the gasoline hydrogenation unit are equipped with self-starting interlocks. As these pumps draw out sewage and sludge oil, the liquid level in the tanks drops, creating negative pressure that can allow air to enter the tanks. The drainage systems for the sewage tanks and sludge oil tanks are connected to the flare system, which can also lead to air entering the flare system and pose safety risks. Discuss how to avoid such situations from occurring. Thank you to all the experts
Just connect the vent directly to the flare line and turn it on; that will create a balance line.
This type of medium should be equipped with a nitrogen seal.
Isn’t your oil sludge tank equipped with a vent line connected to the flare system? Oil sludge tanks are generally closed systems, and under normal conditions they need to be connected to a flare system in order to maintain a slight positive pressure.
It won’t work if air enters the flare during regeneration
Should nitrogen be supplied continuously during regeneration? Is it necessary to add an online oxygen content analyzer or something like that?

Yes, it’s that during regeneration, there’s a concern about burnt air coming in
