restirction Orifice Sizing
restirction Orifice Sizing
(OP)
need to size restriction orifice for liquid service (water with some methanol). Upstream presure 500 psig/45 F, 62 lb/CF. Downstream pressure 0 to 50 psig. Is multiple restriction orificea way to go? How many? Took total DP thru a single RO, but beta was .14. Any suggestion?

Good luck,

RE: restirction Orifice Sizing
- Provided that the orifice hole is big enough (so it doesn't block) and thick enough (so it doesn't bend), then you only need one orifice.
- Vaporization in relatively thin orifices are unlikely. And even if it does occur to a small degree, not a significant problem.
RE: restirction Orifice Sizing
You don't want a thin plate RO for this service.
Contact one of your pump suppliers, most have a good solution to this problem.
RE: restirction Orifice Sizing
Subject to smaller diameter Pipeline, as High Velocity erosion is usual, thus useful life will be limited accordingly.
