The pour point depressant is produced by using high-pressure multiple polymerization in the ethylene-vinyl acetate system. It has eutectic adsorption with paraffin wax in crude oil, prevents paraffin wax crystals from growing up, reduces the freezing point and viscosity of crude oil, and improves the low-temperature fluidity of crude oil. Adding a certain amount of crude oil pour point depressant to crude oil can significantly improve the low temperature fluidity of crude oil. The temperature of crude oil showing the characteristics of Newtonian fluid can be reduced by 5-10℃, the pour point can be reduced by 10-20℃, and the yield stress value and low-temperature apparent viscosity can be reduced by more than 80%. This is an effective way to realize crude oil gathering and transportation at normal temperature.
Crude oil pour point depressant has a good modification effect on a variety of waxy crude oils in China.
