塔河四区混合原油制取重交通道路沥青的研究 总被引:1,自引:2,他引:1
根据塔河四区混合原油的性质 ,进行了生产 AH-90重交通道路沥青的可行性研究。研究结果表明 ,>4 1 0℃、>4 1 2℃减压渣油符合 AH-90重交通道路沥青指标要求 ,但是 ,随着蒸馏温度的提高 ,1 5℃延度值下降较大 ,生产控制范围窄 ,操作弹性小 ,给生产带来了一定困难。在一定针入度的减压渣油中 ,加入定量的糠醛抽出油 ,各项性能指标完全满足AH-90重交通道路沥青指标要求 ,1 5℃延度和薄膜烘箱试验后 2 5℃延度值均大于 1 0 0 cm。 相似文献

针对沥青质含量较高的塔河原油,采用适当的工艺开发出了符合JTG F40-2004技术要求的SBS改性道路沥青。通过加入稳定剂使SBS与基础沥青反应形成了较稳定的均匀微观结构,从而解决了SBS改性沥青的储存稳定性问题。常规方法评价结果表明,塔河原油SBS改性道路沥青具有较小的感温性以及优良的高低温性能。采用SHRP方法对塔河原油SBS改性道路沥青进行了评价,并与其它油种SBS改性沥青作了比较,结果表明,塔河原油SBS改性道路沥青的SHRP性能等级为PG70-34和PG76-34,具有非常好的高低温性能及抗疲劳开裂性能。 相似文献

The high viscous crude oil from Shuguang No. 1 zone of Liaohe oil field has the characteristics of high density (ρ20 = 0.9977 g cm-3), great viscosity (ν100 = 1223.9 mm2 s-1) and high pour point (48°C), which are similar to those of the residue distillation of general crude oils. It contains no gasoline distillation and the diesel oil fraction yield is just 7.19%. It is often used as fuels after emulsification. But this oil is so vicious that it cannot be atomized uniformly and burned fully. In order to make full use of it, this kind of high viscous crude oil has been evaluated comprehensively and the properties of its various distillations are analyzed respectively. The results indicate that this crude oil contains less wax, but more resins and asphaltene, which belongs to low-sulfur naphthene-base crude oils and it is the suitable material to produce high-quality paving asphalt. Based on its characteristics, the optimum processing scheme is put forward and the high-quality paving asphalt is produced by using the distillation higher than 350°C. 相似文献

Abstract The high viscous crude oil from Shuguang No. 1 zone of Liaohe oil field has the characteristics of high density (ρ 20 = 0.9977 g cm?3), great viscosity (ν 100 = 1223.9 mm2 s?1) and high pour point (48°C), which are similar to those of the residue distillation of general crude oils. It contains no gasoline distillation and the diesel oil fraction yield is just 7.19%. It is often used as fuels after emulsification. But this oil is so vicious that it cannot be atomized uniformly and burned fully. In order to make full use of it, this kind of high viscous crude oil has been evaluated comprehensively and the properties of its various distillations are analyzed respectively.
