Hydrocyklons - MIX WATER AND GAS
Hydrocyklons - MIX WATER AND GAS
(OP)
Hi to everybody.
I need some halp ....
I have stream in pipeline consist of vol% 45% gas, 54,98% oil (emulsion of water in oil)and 0,02% sand.
I would like to ask, does anybody know cyclon which separate at same time sand from gas and oil fluid.
Cyclone - for gas fluid
Hydrociclon - for liquid
DO YOU KNOW FOR SOLVE BETWEEN THESE TWO!
THANK YOU IN ADVANCE!

RE: Hydrocyklons - MIX WATER AND GAS
In any case, using centrifugal acceleration for fluid separation is very dependent on both Weber Number and Reynolds Number. Any swirly device will have a fairly narrow range of Weber Numbers where it optimizes separation, and a slightly wider range where it does anything at all. I have seen a large number of centrifugal separators that failed to work because the flow rate or the mix or the temperature changed a fairly small amount. If you can control the Weber Number to keep it within the devices sweet spot they do well.
It is rare to have that much control over a stream as messy as you describe. Usually if you are flowing gas, emulsion, oil, and sand the flow rates, temperature, pressure, and mixture changes several times a second. Not good for cyclonic equipment.
For a 50/50 gas/non-gas mix I'd use a vertical separator to remove the gas and then look at some kind of heater/treater to deal with the emulsion and sand. It is exceedingly difficult to remove sand from an emulsion by either gravity or acceleration. It is usually best to break the emulsion and then separate the water/oil/sand mix independently. Most common way to do this is a horizontal separator with adequate cleanouts to remove the sand.
