The freezing point of wax is high, so the wax content will affect the freezing point of crude oil. Waxy crude oil refers to the percentage of paraffin and ceresin contained in crude oil at normal temperature and pressure. Paraffin wax is a white or yellowish solid composed of higher alkanes, and its melting point is 37℃ ~ 76℃, which is lower than that of petroleum. The higher the wax content, the higher the wax precipitation temperature. ? The higher the wax precipitation temperature, the higher the freezing point of crude oil.

Note that the picture is the focus of waxy crude oil, which comes from a paper.
