Problems with underground diesel hydrogenation oil tanks
Thread Content
What do your underground diesel hydrotreating sludge tanks look like? Is it a pressure vessel at normal pressure or a pressure vessel? Is the manhole usually closed? Could you elaborate a bit more? Thank you!
In a bedroom-type pressure vessel, the manhole is of course sealed. Because the top of the oil tank must be connected to the device’s low-pressure gas line
Horizontal tank, pressure tank, with the upper part capable of being directly connected to a flare.
Are you a designer? Oil tanks are usually connected to a venting system; with the manhole open, aren’t you worried that oil might leak out?
It is best to use pressure vessels, as they are safer; the manholes must be sealed, as the sulfur content in dirty oil is very high
Well, yes, our manhole isn’t properly sealed, and every time we perform backwashing, there’s a strong hydrogen sulfide smell at the site! !
The manhole for the wax oil cracking and underground waste oil I used before was also open; usually, oil was poured directly into it through that manhole, without any filter screen in place
For some diesel hydrogenation filters, when flushing with steam, it is necessary to keep the underground oil sump vent open, as the lower the outlet pressure during the flushing process, the more thorough the cleaning. If self-flushing with diesel is used, this is not necessary, but the manhole should remain closed.
