Prediction of the Effectiveness of Pour-Point Depressant Additives from Data on the Antioxidant Properties of Crude Oil

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

In order to predict the effectiveness of pour-point depressant additives, we have used data on the redox activity of the pour-point depressants and the crude oil, untreated and treated with the additives. The value of the kinetic criterion K for antioxidant activity depends on the type of additive and its concentration. The highest value of the calculated antioxidant activity index IAO corresponds to the pour-point depressant additive best reducing the viscosity and pour point of waxy crude oil. Using a pour-point depressant with a negative value of IAO leads to poorer rheological characteristics of the crude oil, and an additive with slight pour-point depressant effectiveness has a low IAO.
