辽河油田曙一区高粘度原油密度大 ( p2 0 =0 .9977g·cm- 3)、粘度大 (V80 =564 7.3mm2 ·s- 1)、凝点 (tSP=4 8℃ )高 ,属于低硫环烷基原油。该原油无汽油馏份 ,柴油饱分收率也很低 ,仅占 7.1 9% ,润滑油馏分不适合做润滑油原料 ,而且渣油馏分亦不宜做催化裂化原料。但此油的蜡含量比较低 ,胶质、沥青质含量高 ,是生产沥青的一种优质原料。辽河油田现将其作为烧火油使用 ,但由于其粘度大 ,乳化后不易雾化 ,因而燃烧不充分。这不仅浪费了资源 ,而且无疑也降低经济效益。为合理利用石油资源 ,以辽河油田曙一区高粘度原油的渣油为基础组分 ,以炼厂富芳贫蜡的废油为调合组分进行调合 ,可制备出符合国标GB/T1 51 80 -94要求的各种牌号沥青。实验证明调合的沥青有很好的低温性能和抗老化性能。试验建立的调合剂加入量与调合沥青物性的数学模型 ,定量地反映了调合剂对沥青物性的影响 ,可作为工业沥青生产放大的依据。试验建立的辽曙一区环烷基沥青组成和沥青物性的数学模型 ,为寻找其它调合剂和其它工艺提供了依据。
The viscosity of crude oil with high viscosity (p2 0 = 0.9977g · cm-3), high viscosity (V80 = 564 7.3mm2 · s-1) and freezing point (tSP = 48 ℃) Sulfur naphthenic crude. The crude oil without gasoline distillate, the diesel yield is very low, accounting for only 7.19%, lube oil fraction is not suitable for lubricating oil raw materials, and the residue should not be made of catalytic cracking of raw materials. However, the wax content of this oil is relatively low, gum, asphaltene content, is a high quality raw materials for the production of asphalt. Liaohe Oilfield now use it as a burning oil, but because of its viscosity, emulsification is not easy atomization, and thus inadequate combustion. This is not only a waste of resources, but also undoubtedly reduce economic efficiency. In order to make rational use of petroleum resources, based on the residue of high-viscosity crude oil in Shuyi District of Liaohe Oilfield, 51 80 -94 requirements of the various brands of asphalt. Experiments show that blended asphalt has good low temperature performance and anti-aging properties. The mathematical model of the blending amount of the blending agent and the physical properties of the blended asphalt produced by the experiment quantitatively reflects the influence of the blending agent on the physical properties of the asphalt and can be used as the basis for the enlargement of the industrial asphalt production. The mathematical model of naphthalene asphalt composition and asphalt physical property established in the experiment in Lishu District provided the basis for finding other blending agents and other processes.
