由实沸点蒸馏新疆原油得到200-525℃间每间隔25℃的13个窄馏分,采用落入式铜块热量计测定各窄馏分及225-275℃和 475-525℃两个宽馏分于不同温度下的液体焓值,分别给出焓与温度的关联式。同时,检验焓的加和性,考察了API计算方法对新疆原油的适用性。结果表明,测定的焓值试验精度达到ASTM的要求;新疆原油馏分间焓具有较好的加和怀;API方法基本适用于新疆原油馏分的计算。 相似文献

提出一种利用原油宽馏分数据,预测任何温度范围的馏分油收率和物理性质的方法。首先推导了馏分油性质与馏程起、止温度的二元关系式,然后对馏分油各种性质确定了预测策略,即整体拟合还是局部插植。经过对数百种原油的广泛检验,证明提出的预测方法是适用的。 相似文献

胜利原油酸性组分的结构与界面活性 总被引:6,自引:1,他引:6
通过在硅胶中加入特殊添加剂的TLC方法,对胜利原油的总酸组分按照化学结构和相对分子质量进行了高效的分离.用红外、核磁、元素分析、相对分子质量测定、酸值等方法对各组分的结构进行了表征.测定了它们的动态界面张力并研究了化学结构与界面活性之间的关系.结果表明,酸性组分的族组成与它们的相对分子质量密切相关,并在界面张力中起决定作用.在总酸组分的相对分子质量较低的组分(Mn<500)中,酸的侧链以脂肪烃为主,表现了较强的界面活性.相对分子质量较高的组分(Mn>500), 表现了较弱的界面活性. 相似文献

The characteristics of the high viscous crude from No.1 Shuguang Zone of Liaohe Oil Field are similar to those of residue distillates of general crude such as high density (ρ20 = 0.9977 g.cm-3), high viscidity (ν100 = 1223.9 mm2.s-1) and high solidifying point(SP = 48°C). It contains no gasoline distillate and diesel yield is just 7.19%. And now it is only used as fuel. In order to make full use of this oil, the high viscous crude from No.1 Shuguang Zone of Liaohe Oil Field is evaluated comprehensively. And the properties of various distillates from the crude are analyzed and evaluated respectively. The results indicate that this oil contains less wax, but rich in resin and asphaltene, which belongs to low sulfur naphthene-base crude oil and can be used as feedstock to produce high paving asphalt. According to its characteristics, the optimum processing scheme is put forward and the high grade paving asphalts are produced by using the distillates higher than 350°C. 相似文献
