用蜡晶改进剂改善含蜡原油的低温流动性,是研究实现常温集输和长距离管输的途径之一。国外六十年代就开始了含蜡原油及重燃料油加蜡晶改进剂降凝减粘的研究,并针对不同组成的含蜡原油及重燃料油研制了若干系列蜡晶改进剂和分散剂。为了节省能源消耗,近年来国内对含蜡原油加蜡晶改进剂热处理也进行了一系列实验研究,并取得了一定成果。国外十几个公司也应邀用他们研制的蜡晶改进剂和分散剂对我国大庆等原油进行了筛选实验。由 Improving the low temperature fluidity of waxy crude oil with wax crystal modifier is one of the ways to study the collection and transportation of long-distance pipe at room temperature. In the 1960s, waxy crude oil, heavy fuel oil and wax modifier were added to reduce the viscosity and reduce viscosity. Several wax wax modifiers and dispersants were developed for waxy crude oil and heavy fuel oil with different compositions. In order to save energy consumption, a series of experimental studies have also been carried out on the heat treatment of waxy crude oil plus wax modifier in China in recent years and some achievements have been achieved. More than a dozen foreign companies were also invited to use their development of wax crystal modifier and dispersant on China’s Daqing oil and other screening experiments. by
