THE STUDY OF PRODUCING HEAVY TRAFFIC ASPHALT BY USING THE HIGH VISCOUS CRUDE FROM NO.l SHUGUANG ZONE OF LIAOHE OIL FIELD

ABSTRACT

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(ρ ₂₀=0·9977 g.cm^-3),high viscidity υ ₁₀₀= 1223·9 mm².s-¹) and high carbon/hydrogen ratio. This oil contains less wax, but rich in resin and asphalt, which belongs to low sulfur naphthene-base crude oil and can be used as feedstock to produce high paving asphalt. But now it is used as fuel after emulsificating. In order to make full use of this oil and resolve the problem of paving asphalt demand-supply, various paving asphalts conforming to GB50092-96 standard were produced by blending vacuum residue of the high viscous crude from No.l Shuguang Zone of Liaohe Oil Field and waste oil which is rich in aromatics and poor in wax. The laboratory test results show that modified paving asphalts have good low-temperature properties and antiaging feature.     

Production of High-Grade Asphalt from Liaoshu Crude Oil

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.

Study on Producing Heavy Paving Asphalt

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.

THE EFFECT OF MATTALOPORHYRINS ON ASPHALT OXIDATION. II. THE EFFECT OF VANADYL CHELATES FOUND IN PETROLEUM

Four selected asphalts were blended with zero to five wt. percent of fractions rich in vamady cheltes prepared from two crude oils. The mixture was -coated in a teflon -support, and the whole was heated in an oven at. 113±2°C for 24 hours. The mixture then was analyzed for increases ketone, acid and anhydride functions.

in general, functions rich in vanady ponphyrims tended to promote asphalt oxidation, particularly as measured by increase in kentones. Corelation of vanadyl ponphyrim concentration with asphalt oxidation is observed to the direct only if asphalts are mixed with varying amounts of the same fraction derived from the same crude Possible reasons for this phenomenon are discussed in terms of oxidation susceptibility of aspha1ts, the importance of molecular associations, and the relative catalytic activities of metallaporphyrins and other metal chelates
