Description
Technical field
The invention belongs to road asphalt technical field, be specifically related to raw material and the process of auspicious 16 No. 50 hards grades of bitumen of crude oil production of a kind of Venezuela agate.
Background technology
The development of regional economy, economic interaction increase, promote special bus flow to increase, particularly the increase of heavy vehicle, rut phenomenon is day by day serious, so the requirement of road is also more and more higher, produce high-quality hard heavy duty road asphalt, it is possible to meet the requirement of current road. Hard grades of bitumen is exactly the low grade Colophonium generally said, such as No. 30 Colophoniumes, No. 50 Colophoniumes. The feature of hard grades of bitumen is high temperature antitypy excellent ability, asphalt modulus height, and the advantages such as rutting resistance is good, pavement structure thinner thickness, life-span length are used widely (especially in Europe) abroad. Current domestic south province such as Guangdong, Jiangxi, Hunan all have be carried out popularization and application. Hard grades of bitumen is generally used in bituminous paving, cutting optimal, can meet the bituminous paving requirement to crack resistance at low-temperature, can increase substantially again the high temperature antitypy ability of bituminous paving.
Considering that crude oil in China more than 80% belongs to paraffinic base crude oil, paraffin content is higher, should not produce road asphalt. And being significantly increased of imported crude oil particularly heavy crude ratio in recent years, adopt import heavy crude to produce hard heavy duty road asphalt, have important practical significance. Import Bachaquero 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 to produce hard grades of bitumen raw material.
Summary of the invention
Instant invention overcomes shortcoming of the prior art, provide raw material and the process of auspicious 16 No. 50 hards grades of bitumen of crude oil production of a kind of Venezuela agate, these No. 50 hard heavy duty road asphalt excellent product performance, meet No. 50 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, include by weight percentage: the auspicious 16 crude oil 50-90% of Venezuela's agate, Persian bank crude oil 5-35%, Bachaquero crude oil 2-15%, tapped oil 3-15%.
The process of auspicious 16 No. 50 hards grades of bitumen of crude oil production of a kind of Venezuela agate, comprises the following steps:
A), after auspicious 16 crude oil of Venezuela's agate, Persian bank crude oil, Bachaquero crude oil are concocted, after heat exchange, primary distillation tower is entered;
B) 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;
C) 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;
D) 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. 50 matrix pitches by controlling vacuum furnace furnace temperature, Top of Vacuum Tower vacuum and asphaltic products needle penetration;
E) No. 50 matrix pitches obtain No. 50 hards grades of bitumen after concocting with tapped oil.
Further, entering atmospheric tower temperature is 340～370 DEG C, and entering vacuum tower temperature is 330～365 DEG C, and the operation pressure of vacuum tower is 94～100kPa.
Further, entering atmospheric tower temperature is 355～357 DEG C, and entering vacuum tower temperature is 352～354 DEG C, and the operation pressure of vacuum tower is 97～99kPa.
Further, entering atmospheric tower temperature is 352～357 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 auspicious 16 No. 50 hards grades of bitumen of crude oil production of a kind of Venezuela of the present invention agate and process, No. 50 hard heavy duty road asphalts of its production meet No. 50 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.
