Process Fluid Leakage
Process Fluid Leakage
(OP)
In general, what could be the potential causes for the process fluid contaminating the barrier fluid regardless of how high the barrier pressure differential. The seal chamber pressure is monitored and does not vary much, the barrier pressure is always maintained higher, but when the barrier fluid is inspected, it is always contaminated!
Anybody experience this too?

Trust this helps, as this is all I can see causing it.

There are seals that can handle reverse pressure however this will not solve the problem. Sounds like you need operator training on how to operate a Plan 53A system.

Are you using a synthetic barrier fluid?
Synthetic fluids are better at the higher temperatures and you should be using a true barrier fluid (not a lubricating oil) but if you are running a clean product fluid as your barrier – it may be breaking down due to the temperatures.
Do you have cooling water hooked up to the seal pot?
If not you should. If there is no cooling water available, you could install an air cooler to the barrier fluid.
I suggest taking an oil sample and confirming the fluid is contaminated.
