摘要：
High pour point properties of crude oil are generally due to the high wax content, so the study of the laws and the characteristics of wax deposition are significant for taking steps to save energy and transport safely. For the wax deposition of high pour point crude oil on pipeline wall, basing on a small-size wax deposition loop laboratory experimental apparatus to simulate the wax deposition of a tube section, the paper studied wax deposition rate by differential pressure method, analyzed the effect of the oil temperature and the wall temperature on deposition law. The amount of wax-deposit under experimental condition was determined, the thermophysical properties of sediment were tested with differential scanning calorimeter, and further, wax deposit mechanism and the main factors for deposition were researched.
