| titleOfInvention | EVA emulsion type crude oil pour point depressant and preparation method |
| abstract | The application discloses an EVA emulsion type crude oil pour point depressant and a preparation method, which belong to the technical field of petroleum exploitation. The pour point depressant includes the following components by weight: 20% to 30% of modified ethylene vinyl acetate and 70% to 80% of the first solvent; the modified ethylene vinyl acetate includes the following components by weight: 4%～9% ethylene, 20%～25% vinyl acetate, 0.5%～1% acrylate, 70%～80% second solvent and 0.5%～1% initiator; modified ethylene vinyl acetate It is prepared by the following method: adding vinyl acetate, acrylate, initiator and second solvent to the reaction kettle according to the weight parts of each component, pressurizing at a preset temperature, liquefying the ethylene and then adding it into the reaction kettle, keeping the Under constant pressure, stirring, and reacting for a preset time, the solvent and vinyl acetate in the reactant are separated to obtain modified ethylene vinyl acetate. |
