Best water seperators are in the 95% to 99% efficency range. When looking at water seperator products -they typically have ratings for free water and emulsified water. Free water is easily trapped but emulsified is a different story.

They can only take that position if they installed 100% membranes,
separators, etc, etc, etc.

Then the fact that "the BEST separators are in the 95%-99%
efficiency range"...that says to me that maybe the OEMs are NOT
using the 'best', but something less (cheaper)...is this a ditto for
the membrane's too?


Emulsified is another matter, but still in line with the above comment
of how in the world can any OEM deny a warranty based on emulsification?

Now am more certain that the thread(s) on lubricity is only taking
about a band-aid to the H2O problem due to cavitation that then
strips away the exotic coating (DLC) that is weakened by organic amines

I need to read up on what polymer barriers they are using.

In petroleum, a way to do EOR is to inject in a polymer (liquid) to raise the viscosity of the water carrier, then drive the oil toward a producing well using the differential in viscosity --- preventing the oil from forming a emulsion or being left behind.

The kind of polymers used in this water blocking membrane is likely a plastic solid (or mesh) that repels water using the differential in viscosity, or possibly surface tension.

If it is a viscosity based separation, there can be some fancy footwork to raise the efficiency of the waterblock by using multiple layers, with the emulsion addressed using a polymer that "hooks" the oil on the outside (or the water) but not the inside.

Let me think about this.... it is actually a petroleum issue that has been solved in EOR.
