The manufacturing method
of heavy asphalt
1. Introduction

heavy asphalt is an important raw material widely used in the production of chemical products, especially in road construction and waterproof material manufacturing and other fields play an important role. In order to meet the growing market demand, it is urgent to improve the production efficiency and quality of heavy asphalt. This article will introduce the manufacturing method of heavy asphalt in detail, aiming to promote the technological progress and industrial development in this field.

2. raw material preparation

1. crude oil selection: choose high viscosity, high aromatic crude oil as raw material, in order to ensure the quality of heavy asphalt.
2. Raw material treatment: crude oil is desalted, dehydrated and desulfurized to ensure the smooth progress of subsequent processing.

3. production process

1. Atmospheric and vacuum distillation: the treated crude oil is subjected to atmospheric and vacuum distillation, and the hydrocarbon components of different weights are separated to obtain suitable heavy asphalt raw materials.
2. Oxidation reaction: The heavy hydrocarbon components obtained by distillation are oxidized with air to generate colloids and asphaltenes to improve the viscosity of heavy asphalt.
3. blending process: according to the product requirements, the oxidized asphalt with different viscosity and properties is blended to obtain the standard heavy asphalt.

4. quality control

1. laboratory analysis: in the production process, regular laboratory analysis of heavy asphalt, testing its viscosity, penetration, softening point and other key indicators to ensure product quality.
2. Adjust the process parameters: according to the test results, adjust the production process parameters in time to ensure the stability of the quality of heavy asphalt.

5. environmental protection and safety production

1. waste gas treatment: the production process of waste gas desulfurization, denitrification and other treatment, reduce air pollution.
2. Wastewater treatment: The wastewater produced in the production process is subjected to biochemical treatment or physical and chemical treatment, and discharged after reaching the discharge standard.
3. Safety protection: Strengthen the safety management of the production site, improve the safety awareness of employees, and ensure the safety and smooth progress of the production process.

6. optimization and improvement

1. Technology research and development: continue to invest in research and development, explore new heavy asphalt manufacturing technology and methods, improve product quality and production efficiency.
2. Equipment update: regularly update and maintain production equipment, improve the level of automation and intelligence of equipment, reduce energy consumption and production costs.
3. Supply chain management: Strengthen the management of raw material supply chain to ensure the quality and stable supply of crude oil and provide a strong guarantee for the production of heavy asphalt.

7. Conclusion The manufacturing method of

heavy asphalt involves many links and processes, and it is necessary to strictly control the quality of raw materials, optimize the production process, strengthen quality control and environmental protection management. Through continuous technological innovation and equipment renewal, the production efficiency and quality of heavy asphalt can be improved to meet the growing market demand, while reducing production costs and improving the competitiveness of enterprises.
