原油及石油产品倾点测定规范分析

Analysis of Crude Oil and Petroleum Products Pour Point Determination

国际上普遍使用倾点作为评价原油和石油产品低温流动性的指标。对国际上几个主要的倾点测定规范和测试原理进行了详细地介绍 ,并将其与我国目前采用的凝点测定标准进行了对比。分析了倾点和凝点测试结果的主要影响因素 。

Pour point is internationally used to assess the flow properties of crude oil and petroleum products at low temperatures, while in China gel point is used. This paper summarizes the commonly used pour point and gel point determination standards and their testing principles. The main factors which influence the results have been discussed, and several measures have been proposed to improve the reliability.
