Air Eliminator Design

Air Eliminator Design

Air Eliminator Design

(OP)
I am designing a custom vertical air eliminator for use with viscous liquids.  Similar units that I have seen all contain a vertical baffle, but there is no consistency as to which nozzle - inlet or outlet - the baffle lies closest.

On one hand, it makes sense to exit from the larger chamber, thus maintaining a greater reservoir of "air-free" product.  On the other hand, it makes sense to enter the larger chamber, to lessen the velocity of the product and thus allow air to escape before the product moves downstream.  Or perhaps it makes no difference, so long as the product does not flow through with crossing the baffle.  I attach my current concept.  Opinions?

RE: Air Eliminator Design

It might be easier/cheaper to buy one of the new fancy coriolis meters from E&H, Micromotion or Foxboro that all manage air entrained liquids.

I would suspect that the more viscous the fluid the more likely that all the air eliminator will do is void pockets of air and not bubbles which will be more likely to be carried through.

I'm not sure how valuable primary separation using a filter screen will be at higher viscosities - a usual component of air release units for domestic fuels and LPG.
