Abstract
A demulsifier and method for use in oil-spill recovery and clean-up that rapidly and efficiently separates a water/crude oil emulsion into its water and crude oil phases. The demulsifier comprises various mixtures of two components A and B. A is comprised of at least one wetting agent formulated to displace one liquid from the surface of a bi-wetted solid disposed at a boundary of a water droplet and oil phase continuum with another liquid via a reduction of the liquid-solid interfacial tension; and B is comprised of at least one surfactant effective in displacing an indigenous emulsifying surfactant film by another surfactant that permits water droplet coalescence and separation from said oil phase continuum.
