wax deposition

Wax deposition of Xinjiang crude oil is investigated on a test loop and the following conclusion can be derived: the deposit coefficient decreases as the shear stress at the pipe wall increases incurred by the change of the temperature or velocity of tile flow.

通过对新疆的几种油样进行试验研究，结果表明，当温度或流速发生变化从而引起管壁剪切应力变化时，沉积系数随着管壁剪切应力的增大而减小。
