| titleOfInvention | Acrylate copolymer and preparation method thereof, water-in-oil emulsion demulsifier and application thereof |
| abstract | The invention relates to an acrylic copolymer and a preparation method thereof, wherein the acrylic copolymer is prepared by polymerizing a polyoxyethylene polyoxypropylene ether monomer with a double bond at the end group, a hydrophobic monomer and an optional hydrophilic monomer through free radicals; wherein the polyoxyethylene polyoxypropylene ether monomer with the terminal group containing double bonds comprises polyoxyethylene polyoxypropylene ether with allyl alcohol as an initiator; the hydrophobic monomer is selected from butyl acrylate and/or methyl methacrylate; the hydrophilic monomer is acrylic acid. The invention also relates to a water-in-oil emulsion demulsifier, which comprises the acrylate copolymer. The invention further relates to a method for treating a water-in-oil emulsion. When the acrylate copolymer provided by the invention is used as the demulsifier, the surface activity of the demulsifier is enhanced, the demulsification and dehydration performances of the demulsifier on the crude oil-in-oil emulsion are improved, the demulsification temperature is reduced while the dehydration rate of the crude oil emulsion is ensured, and the purposes of energy conservation and consumption reduction are achieved. |
