hi friends i want your help please

if theres is an API Plan 54
API Plan 54 is Pres­sur­ized external barrier fluid system sup­ply­ing clean liquid for an arrange­ment 3 pres­sur­ized dual seal. The barrier liquid is main­tained at a pressure greater than seal chamber pressure and is cir­cu­lated by an external pump or pressure system. and we have some leakage from the external fluid to the process fluid.

the question is:
If there is a leak from the barrier fluid to the process fluid, this will create a chemical reaction and we will had a the blockage in the process pipeline or not.
for information
we use dowtherm Q as process fluid and à mineral oil as barrage fluid at 200°c

The barrier fluid must not only be inert to the Dowtherm Q, it should also be okay with the max operating temp of the Dowtherm. Why do you now have this doubt that this barrier fluid is not inert to this Dowtherm Q? Selection of the barrier fluid is made on the basis that some of this will leak into the hot oil. Did you check with the hot oil manufacturer, Dow Chemicals ?
