Crude oil pour point depressant
Crude oil contains a certain amount of petroleum wax, and the concentration, structure, and molecular weight of these petroleum waxes are closely related to the oil source. During the process of oil extraction, transportation, and storage, due to cooling, these waxes crystallize and deposit on the metal surfaces of downhole equipment, oil pipelines, separators, and storage tanks. Due to the continuous deposition of wax, the flow area of oil pipes is reduced, leading to pipeline blockage and reduced oil recovery efficiency of oil wells. When transporting crude oil through pipelines, a station by station heating process is used to increase the temperature and reduce viscosity of the crude oil, ensuring its original fluidity. Fuel power consumption accounts for about 30% of the oil transportation cost, while the volatile loss of light oil in the crude oil. The addition of crude oil pour point depressants for normal temperature transportation is of great significance in reducing energy consumption. The crude oil pour point depressant developed and produced by our company is prepared by adding a strong polarity group to the ethylene vinyl acetate system and using a high-pressure multi-component polymerization production process. Polymers can undergo eutectic adsorption with paraffin in crude oil, preventing the crystallization and growth of paraffin, reducing the solidification point and viscosity of crude oil, and improving the low-temperature flow performance of crude oil. Adding a certain amount of crude oil pour point depressant can significantly improve the low-temperature flow performance of crude oil. The temperature of crude oil exhibiting Newtonian fluid characteristics 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 achieve normal temperature gathering and transportation of crude oil.
