RE: high water cut in crude oil transfer pump
Increase in power consumed
Both due to increase in fluid density.
Look at pump data sheet compared to actual.
could add 25% to both (SG 0.8 to 1.0)

RE: high water cut in crude oil transfer pump
Thanks for your reply. still I have some doubt.
Yes, increasing the density will increase the pressure and power.
what about the effect on the pump internal parts i.e. is there any possibility for pitting due to cavitation?
what about rotor stability with two phase fluid?? i am more worry about pump healthiness than the more power consumption.
for pump data sheet there are two values for the water cut:
2% aearated water and 1% for entrained water. this is not clear for me!!!
RE: high water cut in crude oil transfer pump
Unless the water is coming through as slugs of water followed by oil the rotor should be ok.
I think aerated water means free water and entrained means in solution or emulsion. Either way it's a very small amount.

RE: high water cut in crude oil transfer pump
Same concern if there is significant amount of gas carryunder from the source separator into the first stage pump suction.
RE: high water cut in crude oil transfer pump
2% water content is not high water cut. For transfer of crude oil to processing facilities, it is usulal to specifiy max 0.5% of basic sediments and water (BS&W). In case of higher water content centrifugal pumps tends to emulsifiy the fluids, which would affect downstream separation facilities. But generally it has no negative effect on the pump itself.
RE: high water cut in crude oil transfer pump
Thanks a lot for your great replies.
Alexander,
Do you mean 5% or 0.5%, can you explain more?
RE: high water cut in crude oil transfer pump
Upstream of course you can get >95% water cut in some places....

RE: high water cut in crude oil transfer pump
Today report showed 5% water cut. Because it is the winter time so separation process is not efficient.
Can we continue running the transfer pump in this condition?
As per Alexander's reply. It is max 0.5%
RE: high water cut in crude oil transfer pump
Export spec is up to you
