Emulsion in oil desander.

[processdream]

Hello Evryone!

Our company is to build a desander consists of a hydro-cyclon and an accumulator tank, for an oil operator in North Sea.
The cyclon effect will remove the sand from the main stream and the sand free stream will be directed to main line.
The question is: "Shall we expect a severe type of emulsion of water and oil?"

Some spec of the Crude and the operating condition are as follow:

GOR = 162.8 Sm³/Sm³,
Water Cut = 81 %
Oil flow rate = 4793 Sm³/d,
Operating Press. = 64 bar
Operating Temp. = 62 C

How can I evaluate if there will be a severe type of emulsion or not? (Any reference book, website or calculation method)

If there will be any Emulsion then what solutions do you recommend?

Thanks in advance.



Regards,
Daniel

it is hard to predict emulsion. it depends on natural surfectans in oil or water and also the shear that your stream is experienced. As far as I know, you can just test your sample to find out emulsion content of it. I think there is one test by Suadi aramco on this.
