Example Embodiment

[0022] Example 1

[0023] A kind of raw material for producing No. 70 bitumen from Venezuelan Persian Canmari 16 blended crude oil, including by weight percentage: 45% of Venezuelan Persian Crude Oil, 48% of Venezuelan Marui-16 Crude Oil, 3% of Bachaquero Crude Oil and Laguna Crude Oil 4%.

[0024] Both Venezuelan Boscan and Marui 16 crude oils are high-sulfur naphthenic oils with high density, high viscosity and low freezing point. The gasoline and diesel fraction yield of Boscan crude oil is about 30%. It is about 43%. The carbon-hydrogen ratio and residual carbon value of the two crude oils are both high, and their properties are similar to the vacuum residue fraction of general crude oil. Because of the high acid value, heavy metal content and high carbon residue, these two kinds of crude oil are not suitable for catalytic cracking raw materials, but they are low in saturated hydrocarbon content, high in colloid and asphaltene content, and low in wax content, so they are ...

Example Embodiment

[0031] Example 2

[0032] A kind of raw material for producing No. 70 bitumen from mixed crude oil of Persian Canmari 16 in Venezuela, comprising: 50% of Venezuelan Persian crude oil, 44% of Venezuelan Marui-16 crude oil, 2% of Bachaquero crude oil and Laguna crude oil 4%.

[0033] Its process method comprises the following steps:

[0034] c) The initial top oil vapor is distilled out from the top of the initial distillation tower, and the initial bottom oil at the bottom of the initial distillation tower is pressurized by a pump and enters the atmospheric furnace for heating, and then enters the atmospheric tower for fractionation;

[0035] d) The constant top oil is distilled from the top of the normal pressure tower, the atmospheric side line oil is distilled from the normal pressure tower side line, and the constant bottom oil is pressurized by the pump and enters the vacuum furnace for heating, and then enters the vacuum tower for fractionation;

[0036] c) The top-redu...

Abstract

The invention discloses raw materials and a technological method for producing No. 70 asphalt with mixed crude of Venezuelan Boscan crude and Venezuelan Merey-16 crude. The raw materials are characterized by comprising the Venezuelan Boscan crude and the Venezuelan Merey-16 crude. The No. 70 heavy traffic road asphalt produced by the technological method disclosed by the invention conforms to the indexes of No. 70 A-level road petroleum asphalt formulated in 'Technical Specifications for Construction of Asphalt Road Surfaces of Roads by Ministry of Communications' JTGF40-2004, and the indexes of the No. 70 heavy traffic road asphalt are better than indexes of Chinese national standard (GB50092-96). The high-grade road asphalt is produced by straight distillation of an atmospheric and vacuum distillation unit, and the production process is simple, so that the method is the most economic and convenient method for producing the asphalt; besides, the produced products are excellent in properties, and can completely replace imported high-grade road asphalt, so that needs for high speed development of road construction and high speed development of national economy in China can be met.

Description

technical field [0001] The invention belongs to the technical field of road asphalt, and in particular relates to a raw material and a process method for producing No. 70 asphalt from Persian Camari 16 mixed crude oil in Venezuela. Background technique [0002] In recent years, the prosperity of my country's economy has promoted the rapid development of highway transportation. A large number of expressways have been built or are being built one after another. However, the output of asphalt, especially high-grade road asphalt, in my country is far from keeping up with the needs of road construction. Imported asphalt still holds a significant market share. Due to the constraints of the nature of domestic crude oil, the quality of road asphalt produced by most domestic crude oil cannot meet the requirements. Generally speaking, No. 70 asphalt with a wax content of less than 2.2% and a ductility of more than 15cm at 15°C in the film oven test is used by the transportation depart...
