Abstract: A method to reduce the freezing point of waxy crude oil from the jianghan oil field with the use of additive and application of heat treatment is discussed. It is claimed that the freezing point can be reduced by 7～16℃ with the use of EVA, paradyne-70 and Shellswin-5T. The mechanism of additives and heat treatment is dealt with at some length and the factors influencing the depression of freezing point are also touched upon.
