I am trying to get more information and references from separation gurus out there regarding the mousse effect that can be apparent with certain crudes. The "mousse" effect wherein excess gas is trapped within the oil phase exiting say a production separator. The mousse is oil entrapped with small dispersed gas bubbles.
I appreciate that this tendency would be case specific and to understand crude characteristics tests are required for the particular crude in question. However I would appreciate any general feedback and references to correlations that you may know of that perhaps indicate what a respectable or common allowance is for moussing or gas volume carry-under with oil. In this case oil stream exiting a three phase separator (oil/water/gas) which then feeds a degasser where the gas is recovered and compressed. In designing the degasser and particularly selecting the compression capacity the allowance for moussing can be a critical parameter in the sense of over or under designing. In this case the crude is heavy 20°API and exhibits stable emulsion characteristics.
Thanks
