In the preferred heat treatment conditions can be improved low temperature flow properties of crude oil. 1995 annual output of 7.9 million tons of crude oil.
Oil machine treatment is heated to a certain temperature, then a certain way and speed cooled to a temperature of the process. After heat treatment, make crude paraffin, asphalt and glial changes in  oil expeller , so that the freezing point and viscosity of the oil change.
