Description
Technical field
The invention belongs to road asphalt technical field, be specifically related to raw material and the process of a kind of Venezuela Persian No. 70 Colophoniumes of bank crude oil production.
Background technology
In recent years, the prosperity of China's economy has promoted the high speed development of highway communication cause, large quantities of highways build up or under construction in succession, but the yield of China's Colophonium particularly asphalt for high grade road does not also catch up with far away the needs of highway construction, and Imported Asphalt still occupies the important market share.Due to the restriction by domestic oil property, the road asphalt of most of domestic crude oil production can not meet requirement in quality.It is said that in general, wax content is lower than 2.2%, the 15 DEG C of ductilities of Thin Film Oven Test TFOT No. 70 Colophoniumes more than 15cm, traffic department just uses it as high grade pavement pavement material.Crude oil in China more than 80% belongs to paraffinic base crude oil, and paraffin content is higher, should not produce road asphalt.
Along with highway in China transport and communications amount sharply increases, overload, heavy duty phenomenon are serious, and the damaged condition of pavement structure is increasingly sharpened, and bituminous concrete high-temperature stability deficiency forms rut, are one of the Major Diseases forms of China Higher level asphalt highway.
Along with the increase of imported crude oil particularly heavy crude ratio, adopt import heavy crude to produce heavy duty road asphalt, have important practical significance.
Venezuela's Persian bank crude oil belongs to high-sulfur naphthene base crude oil, and oil density is big, and viscosity is big, condensation point is low, and gasoline, diesel fraction yield is about 30%, and hydrocarbon when carbon residue is all higher, and its character is similar to the vacuum residue fraction of general crude oil.Because of this acid value for crude oil, content of beary metal height, carbon residue is high, should not make catalytically cracked material, and saturated hydrocarbon content is low, and colloid, asphalt content are high, and wax content is little, is suitable for making high-quality asphalt raw material very much.
Summary of the invention
Instant invention overcomes shortcoming of the prior art, provide raw material and the process of a kind of Venezuela Persian No. 70 Colophoniumes of bank crude oil production, these No. 70 heavy duty road asphalt excellent product performance, meet No. 70 A level bi tumenf orr oad indexs formulated in " Ministry of Communications's standard specification for construction and acceptance of highway asphalt pavement " JTGF40-2004, be better than the indices of GB (GB50092-96).
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions:

Further, La Guna crude oil is also included.
Further, include by weight percentage: Venezuela Persian bank crude oil 70-90%, Bachaquero crude oil 5-20% and La Guna crude oil 2-10%.
The process of a kind of Venezuela Persian No. 70 Colophoniumes of bank crude oil production, comprises the following steps:
A) just oil vapour in top distillates through fore-running tower top, and the first base oil bottom primary distillation tower enters through pump pressurization and enters atmospheric tower fractional distillation after atmospheric pressure kiln heating；
B) often top oil distillates through Atmospheric Tower, and atmospheric side draw oil product distillates through atmospheric tower side line, and normal base oil enters through pump pressurization and enters vacuum tower fractional distillation after vacuum furnace heating；
C) subtract top oil to distillate through Top of Vacuum Tower evacuation, decompression sideline product distillates through vacuum tower side line, the decompression residuum of vacuum tower bottoms and Colophonium are after pump pressurizes, carrying device after heat exchange, cooling, obtains No. 70 Colophoniumes by controlling vacuum furnace furnace temperature, Top of Vacuum Tower vacuum and asphaltic products needle penetration.
Further, entering atmospheric tower temperature is 340～370 DEG C, and entering vacuum tower temperature is 330～360 DEG C, and the operation pressure of vacuum tower is 92～100kPa.
Further, entering atmospheric tower temperature is 348～350 DEG C, and entering vacuum tower temperature is 352～354 DEG C, and the operation pressure of vacuum tower is 97～99kP.
Further, entering atmospheric tower temperature is 350～352 DEG C, and entering vacuum tower temperature is 354～356 DEG C, and the operation pressure of vacuum tower is 96～98kPa.
Compared with prior art, the invention has the beneficial effects as follows:
The raw material of a kind of Venezuela of the present invention Persian No. 70 Colophoniumes of bank crude oil production and process, No. 70 heavy duty road asphalts of its production meet No. 70 A level bi tumenf orr oad indexs formulated in " Ministry of Communications's standard specification for construction and acceptance of highway asphalt pavement " JTGF40-2004, are better than the indices of GB (GB50092-96).Atmospheric and vacuum distillation unit straight run is adopted to produce asphalt for high grade road, production process is simple, it is produce that Colophonium is most economical, method easily, and the excellent product performance produced, may replace import asphalt for high grade road completely, meet the road construction of China's high speed development and the needs of the national economic development.
