The present invention relates to a kind of method of No. 70 A grades of road asphalts of (Merey16) crude oil production of Venezuela's agate auspicious 16.Auspicious 16 crude oil of Venezuela's agate had both obtained No. 70 A grades of road asphalts after the Atmospheric vacuum process working processes such as electro-desalting → primary distillation tower → atmospheric pressure kiln → atmospheric tower → vacuum furnace → vacuum tower.Pitch produced by the invention meets《Ministry of Communications's standard specification for construction and acceptance of highway asphalt pavement》The index request of No. 70 A grades of road asphalts specified in (JTG F40 2004).This method production process is simple, and without transforming atmospheric and vacuum distillation unit, a route that flow is short, economic benefit is good is provided for the processing of auspicious 16 crude oil of import Venezuela agate.This method is highly suitable for processing refinery's popularization and application of auspicious 16 crude oil of Venezuela's agate.
Description
Technical field
The invention belongs to technical field of petrochemical industry, more particularly to a kind of (Merey16) crude oil of Venezuela's agate auspicious 16 life
The method for producing No. 70 A grades of road asphalts.
Background technology
In recent years, with expanding economy, investments in highway building are improved constantly, and the demand of China's road asphalt is increasingly
Greatly, pitch Apparent con- sumption, import volume are also improved year by year.Crude oil in China 80% or so is paraffinic base crude oil, it is impossible to be used in production
Road asphalt can not especially produce high grade heavy traffic paving asphalt.With the continuous improvement of crude oil in China external dependence degree, a large amount of imports
Crude oil enters China market.Imported crude oil nature difference is larger, and machining process route is not quite similar.High sulfur content, high metal contain
Amount, heavy crude are always the problem for perplexing China's Refiners.
Auspicious 16 crude oil (Merey-16) the category high-sulfur heavy intermediate base crude of import Venezuela agate, because density is big, sulphur contains
Amount is high, nitrogen content is high, nickel content of vanadium is high, is unfavorable for common hydroprocessing technique route processing；Additionally, due to the auspicious crude oil decompression of agate
Residual oil Conradson carbon residue content height, asphalt content height are added significantly to the difficulty of delayed coking processing route.
The content of the invention
The invention provides a kind of method of No. 70 A grades of road asphalts of (Merey16) crude oil production of Venezuela's agate auspicious 16,
No. 70 A grades of road asphalt excellent performances, meet《Ministry of Communications's standard specification for construction and acceptance of highway asphalt pavement》(JTG F40-2004)
Specified in No. 70 A grades of road asphalt indexs.
The present invention is achieved by the following technical solutions：
A kind of method of No. 70 A grades of road asphalts of (Merey16) crude oil production of Venezuela's agate auspicious 16, it is characterised in that：
(Merey16) crude oil of Venezuela's agate auspicious 16 is through with after atmospheric tower, the heat exchange of vacuum tower sideline product, entering one, two, three electro-desalting
Tank carries out desalting processing and water filling and demulsifier.
Auspicious 16 crude oil of agate is flashed into primary distillation tower after desalination, and just top gasoline is distillated；Primary distillation tower base oil through pumped pressurization with
Enter atmospheric pressure kiln after atmospheric tower, the heat exchange of vacuum tower sideline product.After normal pressure stove heat enter atmospheric tower be fractionated, often push up gasoline,
Atmospheric side draw oil is distillated.
Normal base oil is mixed into after decompression stove heat into vacuum tower with decompression Excess vaporization oil and carries out vacuum distillation.Subtract top production
Product, vacuum tower sideline product are distillated.Decompression residuum is pitch carrying device after heat exchange cooling, by controlling normal pressure outlet of still temperature
Degree, decompression heater outlet temperature, Top of Vacuum Tower operating pressure, VACUUM TOWER BOTTOM liquid level are met《Ministry of Communications's asphalt highway is applied
Work technical specification》No. 70 A grades of road asphalts specified in (JTG F40-2004).
