Abstract:
A demulsifying agent comprising at least one maleic acid derivative may be added to a hydrocarbon stream in an effective amount where the hydrocarbon stream includes a plurality of solids that are less than 0.45 microns in size. The demulsifying agent may be added to the hydrocarbon stream at a location that is upstream from a desalter. The demulsifying agent may water-wet at least a portion of the solids for subsequent separation of the solids from the hydrocarbon stream.

Claim (Index 11):
A method for separating at least a portion of solids from an oil phase of an emulsion, wherein the method comprises:\n adding a demulsifying agent comprising at least one maleic acid derivative to the emulsion in an amount ranging from about 0.1 ppm to about 200 ppm based on the emulsion, wherein the demulsifying agent water-wets a plurality of solids within the emulsion; and separating the water-wet solids from the oil phase of the emulsion into a water phase; wherein the solids are substantially oil-free.
