Abstract: A static desalter simulator apparatus has a housing for containing a liquid bath and a rack disposed within the housing. The rack is formed of at least two substantially parallel plates separable by a plurality of spacers. An electric field is generatable between the plates, and at least one of the plates includes at least one recess. The apparatus also includes at least one mixing tube for containing an oil-water emulsion, which is positionable within at least one of the recesses. A controller is operatively connected to a mixing tube. An imaging device for generating a digital image or video during a demulsification process is in a mixing tube.

Abstract: A small-scale static simulator for crude oil refinery desalters has an oil bath, a portion of which is made of a transparent material, a heater/circulator configured to control the temperature of the oil bath and an emulsion-forming device. The desalter simulator also includes a plurality of mixing tubes, each mixing tube having a cap member with a blending assembly configured to work with the emulsion-forming device to emulsify an oil/water mixture contained in the mixing tube. A tube-holding rack is received in the oil bath. The tube-holding rack has a plurality of parallel plates, said plates having openings forming mixing tube receiving apertures.

Abstract: A multi-component demulsifier comprising an alkoxylated C5-C7 alkyl substituted phenol-formaldehyde resin and at least one polyalkylene oxide triblock copolymer. This synergistic combination of materials is useful in breaking emulsions, of water in hydrocarbon or hydrocarbon in water.
