石油产品低温性能指标检测方法的现状及发展

Status and development of the testing methods concerning the low temperature performance indexes of oil products

石油产品低温性能是衡量石油产品在低温条件下能够正常流动和顺利输送的能力,用来评价此性能的指标包括结晶点、冰点、浊点、冷滤点、倾点和凝点等等。本文主要介绍现阶段应用比较广泛的低温性能指标检测方法,以及对目前的低温性能指标检测方法现状分析存在的问题和不足并对未来的发展进行展望。

The low temperature performance of oil products is a measure of the normal flow and smooth con- veying capacity of oil products under the condition of low temperature.The indexes involved in the evaluation of the performance include crystallization point, freezing point,cloud point,cold filter point, pour point and solidification point,etc.The paper mainly expounds on the prevailing test methods of low temperature performance indexes that have been widely applied. In addition, with the analysis of the status quo of the testing methods concerning the low temperature performance indexes, some problems and deficiencies are identified in the paper, and the relevant development prospect in the future is also presented.
