Embodiment 1

[0099] Embodiment 1: Asphalt is produced by blending catalytic cracking oil slurry and deoiled hard asphalt.

[0100] Catalytic cracking oil slurry is the oil slurry left in the catalytic cracking process in the oil refining process. It is a low value-added product. At present, domestic catalytic cracking oil slurry is generally shipped as cheap heavy fuel oil. The viscosity of FCC oil slurry is low, which cannot reach the viscosity range required by bitumen. Deoiled hard asphalt refers to the residue left after the vacuum residue has been removed by solvents to remove most of the saturated hydrocarbons and lighter aromatic hydrocarbons. Hard and brittle at room temperature, it is difficult to be used as a blending component in asphalt production.

[0101] In this example, the viscosity model of catalytic cracking oil slurry and deoiled hard asphalt is established, and qualified asphalt can be produced by blending the two raw materials in an appropriate ratio. The specific o...

Embodiment 2

[0113] Example 2: Production of asphalt using vacuum residues of two unconventional asphalt crude oils.

[0114] Among the more than 1,500 kinds of crude oil produced in various crude oil producing areas in the world, only 260 kinds of crude oil can be directly produced asphalt. In this example, a viscosity model is established for the vacuum residues of two unconventional asphalt production crude oils: Sudan crude oil and Philippine crude oil, and a scheme for blending these two vacuum residues to produce asphalt is found. Sudan crude oil is dense, and the viscosity of its vacuum residue exceeds the quality specification for bitumen production. The Philippine crude oil is less dense, and the viscosity of its vacuum residue is less than the quality specification for bitumen production. Both of these crudes are therefore generally not bitumen producing crudes. In this example, the asphalt was produced by blending the vacuum residue of these two crude oils through the asphalt ...

Abstract

The invention provides a method for determining an asphalt concoction scheme based on a viscosity model. The method comprises the steps of measuring asphalt viscosity, establishing a viscosity model parameter database, and adjusting and determining an asphalt concoction model through correlation between an asphalt target technical index and the viscosity. The invention also provides a corresponding database and system. The method and the system have the characteristic of realizing quick, convenient and efficient design and optimization of the asphalt concoction scheme.

Description

[0001] The patent application for the present invention applied for the same utility model on the same day. technical field [0002] The invention belongs to the field of asphalt production in petroleum refining industry. Background technique [0003] Asphalt production is an important part of the petroleum refining industry. It is the residue of crude oil after distillation. It has the highest boiling point in the entire crude oil composition and is the heaviest component in crude oil. Asphalt is widely used in highway pavements, building roofs, waterproofing of ground and underground structures, and anti-corrosion of wood and steel. my country's current bituminous output exceeds 20 million tons. However, the output of domestic asphalt is still in short supply compared with the demand of my country's domestic market, especially the high-end modified asphalt market. Therefore, increasing asphalt output and improving asphalt performance are problems that the asphalt product...
