Problems solved by technology

However, the asphalt quality indicators in foreign countries are quite different from those in my country. It is difficult for asphalt products produced by using our traditional petroleum refining raw materials, formulas and processes to meet the quality standards of foreign asphalt.
[0003] For example, although the annual import demand of asphalt products in Australia is as high as one m...

Embodiment 1

[0033] (1) After heating 100 parts by mass of vacuum residue to 150°C, inject it into an asphalt mixing tank, and perform mechanical stirring at 150°C.

[0034] (2) The 60°C dynamic viscosity index of the vacuum residue oil was detected, and the detected value of the 60°C dynamic viscosity index of the vacuum residue oil was 466 Pa.s.

[0035] (3) Inject 5 parts by mass of the extracted oil into an asphalt blending tank and perform mechanical stirring and blending with the vacuum residue at a temperature of 150° C. for 6 hours.

[0036] (4) After the mixing and blending is completed, the finished product is put into an asphalt storage tank for storage at a storage temperature of 120°C, and it will leave the factory within 15 days of storage.

[0037] The vacuum residue in this example is produced by mixing Iranian heavy crude oil and Egyptian Belayim crude oil at a ratio of 9:1 and then deep-drawing through a 10 million-ton atmospheric and vacuum distillation device, with a pe...

[0040] (1) After heating 100 parts by mass of vacuum residue to 150°C, inject it into an asphalt mixing tank, and perform mechanical stirring at 150°C.

[0041] (2) The 60°C dynamic viscosity index of the vacuum residue oil was detected, and the detected value of the 60°C dynamic viscosity index of the vacuum residue oil was 473Pa.s.

[0042] (3) Inject 5 parts by mass of the extracted oil into an asphalt blending tank and perform mechanical stirring and blending with the vacuum residue at a temperature of 150° C. for 6 hours.

[0043] (4) After the mixing and blending is completed, the finished product is put into an asphalt storage tank for storage at a storage temperature of 120°C, and it will leave the factory within 15 days of storage.

[0044] The vacuum residue in this example is produced by blending Saudi medium crude oil and Colombian Castile crude oil at a ratio of 3:1 and then deep-drawn through a 10 million-ton atmospheric and vacuum distillation unit, with a penet...

Embodiment 3

[0047] (1) After heating 100 parts by mass of vacuum residue to 145°C, inject it into an asphalt mixing tank, and perform mechanical stirring at 145°C.

[0048] (2) The 60°C dynamic viscosity index of the vacuum residue oil was detected, and the detected value of the 60°C dynamic viscosity index of the vacuum residue oil was 369 Pa.s.

[0049] (3) Continue to mechanically stir the vacuum residue at a temperature of 145° C. for 1 hour.

[0050] (4) After the mixing and blending is completed, the finished product is put into an asphalt storage tank for storage at a storage temperature of 120°C, and it will leave the factory within 15 days of storage.

[0051] The vacuum residue in this example is produced by blending Iranian heavy crude oil and Egyptian Belayim crude oil at a ratio of 9:1 and then deep-drawing through a 10 million-ton atmospheric and vacuum distillation unit, with a penetration of 531 / 10mm.

Abstract

The invention discloses Australian C-320 asphalt and a production method thereof. The asphalt provided by the invention is prepared from the following components in parts by mass: 100 parts of vacuumresidues, 0-5 parts of extract oil and 0-10 parts of hard asphalt. Specific appropriate crude oil is subjected to a specific mixed refining proportion and a specific production technology to produce the vacuum residues, then the vacuum residues are mixed with the extract oil and hard asphalt of specific requirements according to specific conditions, and thus an asphalt product meeting the standardrequirements of the Australian C-320 asphalt is produced; and therefore the problem that an asphalt product produced by traditional petroleum refining raw materials and production process cannot meetthe quality standards of the Australian C-320 asphalt is solved.

Description

technical field [0001] The invention relates to the field of petroleum processing products, in particular to an Australian C-320 bitumen and a production method thereof. Background technique [0002] In recent years, with the increasing oil refining capacity of domestic refineries, domestic asphalt production capacity has also increased rapidly, resulting in fierce competition in the domestic asphalt product market, especially homogeneous competition. In order to seek higher profits and sales, domestic oil refiners hope to produce asphalt products that meet foreign standards. However, there is a big difference between foreign asphalt quality indicators and our country's asphalt quality indicators. It is difficult for asphalt products produced by our traditional petroleum refining raw materials, formulas and processes to meet foreign asphalt quality standards. [0003] For example, although Australia’s annual import demand for asphalt products is as high as one million tons,...
