| titleOfInvention | ENVIRONMENTALLY SUSTAINABLE DESEMULSIFIERS |
| abstract | This invention relates to environmentally friendly demulsifiers useful for breaking emulsions, e.g. ex. water-in-oil and oil-in-water emulsions, especially oil-field emulsions, where the demulsifiers are polymers obtained by reacting a suitable resin with at least two different monomers, one having a Hansen solubility parameter similar to ethylene oxide and the other having a Hansen solubility parameter similar to propylene oxide, and the polymers are characterized by an absence of ethylene oxide and / or propylene oxide. In a non-limiting embodiment, suitable resins include butyl resin, nonyl resin, nonyl / butyl resin, amyl resin, nonyl / butyl / amyl resin, phenol / formaldehyde resin, and combinations thereof. Suitable monomers include caprolactone, lactic acid, lactide, methacrylic acid ester, stearyl ester, hexyl ester, lauryl ester, urethane, adipate, and the like. ethylene, vinyl esters, amides, allylic ethers, vinyl ethers, vinyl chloride, vinyl acetate, acrylic acid methyl ester, and combinations thereof. |
