The nature and use
of aromatic residue/residual liquid in the field of chemical production raw materials
1. Introduction

Aromatic residue/residual liquid is an important chemical production raw material, widely used in petroleum, chemical, energy and other fields. In this paper, the properties and uses of aromatic residue/raffinate are introduced in detail, in order to provide reference for the production and research in related fields.

2. the properties of aromatic residue/raffinate

Aromatic residue/raffinate is a complex mixture, mainly composed of hydrocarbons, including aromatic hydrocarbons, alkanes, naphthenes and other components. Its nature varies due to different sources and production processes, but it usually has the following characteristics:

1. High viscosity: The viscosity of aromatic residue/raffinate is higher, which makes it better in some applications Lubrication performance.
2. High aromatic content: Aromatic residue/raffinate is rich in aromatic components, which makes it have high calorific value and chemical activity.
3. containing impurities: aromatic residue/residual liquid may contain some impurities, such as nitrogen, sulfur and other elements, these impurities may have a certain impact on the subsequent processing process.

3. the use of aromatic residue/raffinate

Aromatic residue/raffinate has a wide range of uses in the field of chemical production raw materials. The following are the main aspects:

1. as fuel: aromatic residue/raffinate has a high calorific value and can be used as fuel for boilers, kilns and other thermal equipment.
2. Production of carbon black: aromatic residue/residual liquid can be used as raw material to produce carbon black. Carbon black is an important chemical raw material, widely used in rubber, plastic, ink and other fields.
3. Production of chemicals: The aromatic components in the aromatic residue/raffinate can be used to produce various chemicals, such as benzene, toluene, xylene, etc.
4. production of asphalt: aromatic residual oil/residual liquid can be used as raw materials to produce asphalt, asphalt is widely used in road construction, waterproof materials and other fields.

4. conclusion

aromatic residue/raffinate as an important raw material for chemical production, has a wide range of uses. In actual production, appropriate processing methods and process conditions should be selected according to its specific properties and application requirements to achieve efficient utilization of aromatic residue/raffinate and product quality. At the same time, for the production and use of aromatic residual oil/residual liquid, it is also necessary to pay attention to environmental protection and safety issues, and take effective measures for waste treatment and emission control to ensure the safety and sustainability of production.

The above is a brief introduction to the properties and uses of aromatic residue/raffinate in the field of chemical production raw materials. Hope to be able to provide some reference and help for the production and research in related fields.
