| titleOfInvention | Environmentally friendly demulsifiers |
| abstract | Environmentally friendly demulsifiers are useful to break emulsions, e.g. water-in-oil and oil-in-water emulsions, particularly oilfield emulsions, where the demulsifiers are polymers made 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 where the polymers have 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, ethylene adipate, vinyl esters, amides, allyl ethers, vinyl ethers, vinyl chloride, vinyl acetate, acrylic acid methyl ester, and combinations thereof. |
