Air Bleed for Crude Oil Vessel
Air Bleed for Crude Oil Vessel
(OP)
Hey guys,
I cant seem to find an off-the-shelf solution for this problem.
Basically, I need an air bleed that can distinguish between oil and air. Under pressure, it'll bleed all the air in the pipe until none is left, then it's close before oil comes out.
I've found this (Parker ELA Valve, but it's not made for crude oil. Any suggestion on who to look for?

If you you are interested in capturing the exhausted gas for sale, you could use my patented GasBuster which would work, but is most probably overkill (it costs around $30k)

I'm looking for something smaller however.
I can put a hole at the top of my current vessel, and I'd like to be able to bleed gas through that hole with this unknown fitting during the fill-up process. If I'm able to use it automatically all the time, that'd be perfect as well. The linked product is much to larger and costly.

This Parker ELA valve does EXACTLY what I want, but it isn't designed for crude oil. I need one for crude and I can't find it.

It is a really good idea to route the air vent to a slop oil tank because these things really do make a big mess.

Most of these systems I've seen are for water and not high pressure. The potential for leakage is quite high. A water leak is one thing, crude oil is another.
What is the system that needs something like this? Removal of the potential for leakage is better.
Otherwise a relatively simple level switch and valve control loop would be better and a gas boot to give it some time.
