| titleOfInvention | A kind of crude oil pour point depressant and its preparation method and application |
| abstract | The invention provides a crude oil pour point depressant, a preparation method and application thereof. The pour point depressant is a mixture of rhamnose alkyl acrylate polymer and fumarate polymer. The preparation method includes the following steps: (1) mixing the rhamnose ester, a solvent, a first initiator and a polymerization inhibitor, heating until the rhamnose ester is completely melted, and then adding an alkyl acrylic acid polymer to carry out an esterification reaction to obtain rhamnose alkyl acrylate polymer; (2) heating and stirring the rhamnose alkyl acrylate polymer, fumarate polymer, and solvent described in step (1) until they are uniformly mixed to obtain the crude oil coagulant. The pour point depressant combines the advantages of polymer type and surfactant type pour point depressant, with low dosage, good pour point and viscosity reduction effects, and is suitable for high pour point and high viscosity oil in different blocks, high water content, high pour point and high viscosity. Oil is universal. |
