The highly viscous crude oil from Shuguang No.1 zone of Liaohe oifield features high density,high viscosity and low wax content.It contains no gasoline fraction and its diesel oil fraction yiled is only 7.19%,which belongs to the low sulfur naphthenic stocks crude oil.Its heavy fraction is not suited for producing lubricating oil.Its heavy oil,whick contains more resins nd asphaltens and less wax,is not an ideal feedstock for catalytic cracking ,but is the ideal raw material for producing high-grade paving asphalt.Now this highy viscous crude oil is used as fuel oil after being emulsified in Liaohe oilfield,but its viscosity is so hight tha it cannot be atomized uniformly and burned completely,resuting not only in waste of oil resource but also in reduction of economical benefit.To make full use of this oil resource and alleviate the shortfall of high grade paving asphalt in China,various brands of asphal meeting Q/SHR003-1998 and ESSO specifications were developed by blending vaceuum residue of the said oil and a blending compo-net which are rich in aromatics and deficient in wax.The impct of blending component on proerties of blended ashalt has been investigated and road perfomances of these blended asphalts were studied.The labroatory test results show that the blended asphalts have good road performance and antiaging property. 相似文献

Abstract The experiment of producing paving asphalt was performed by blending the deoiled asphalt and the residue fluid catalytic cracking (RFCC) slurry according to the uniform design method. The experiment scheme was designed by choosing the full-fraction FCC, above 400°C slurry, above 445°C slurry, and deoiled asphalt as factors. The mathematical model of blending components and asphalt properties was established by gradual regression. The effect of the blending components on the asphalt properties was reflected quantitatively, and it was found that above 400°C slurry was the optimal component. Using FCC slurry as modifier not only makes full use of the FCC slurry but also improves the property of deoiled asphalt. Based on the mathematical model, the predicted results conformed to the measured results. The paving asphalt produced by blending the deoiled asphalt with FCC slurry can meet the national standard in China. 相似文献

Abstract The high viscous crude oil for Shuguang No. 1 zone of Liaohe oilfield has the characteristics of high density (ρ20 = 0.9977 g.cm?3), high viscidity (ν100 = 1,223.9 mm2.s?1), and high solidifying point (SP = 48°C), which belongs to low sulfur naphthene-base crude oil. The comprehensive evaluations indicate that this oil has no gasoline fraction and the diesel oil is only 7.19%. In addition, the lubricating oil distillate is not suited to produce lubricating oil and heavy oil is not good feedstock for catalytic cracking. However, the low wax and high resin, as well as asphaltene content, make it an ideal raw material for producing paving asphalt. The vacuum residue of this crude acted as base oil and three kinds of waste oil with high aromatics and low wax content were selected as blenders. Various brands of high-grade paving asphalts meeting GB/T15180-94 (China) specification were produced by blending method. The blending effects were investigated and corresponding mathematics models were set up. 相似文献
