C9 petroleum resin manufacturing method

1. Introduction

C9 petroleum resin is an important chemical production raw materials, widely used in rubber, coatings, inks, adhesives and other fields. This paper will introduce the manufacturing method of C9 petroleum resin, including raw material selection, reaction principle, process flow, equipment selection and so on.

2. raw material selection

The main raw material of C9 petroleum resin is C9 distillate oil, which contains more olefins, naphthenes and aromatic hydrocarbons and other compounds. In order to ensure the quality and yield of the resin, it is necessary to select the C9 distillate oil containing higher olefins as the raw material.

3. reaction principle

The manufacturing process of C9 petroleum resin is mainly realized by thermal polymerization reaction. Under high temperature conditions, the olefins, naphthenes and other compounds in the C9 distillate will undergo free radical polymerization to produce high molecular weight polymers. At the same time, some cross-linking reactions will occur, so that the polymer molecules form chemical bonds, thereby obtaining a resin with a certain strength and viscosity.

4. Process

The manufacturing process of C9 petroleum resin mainly includes the following steps:

1. Raw material pretreatment: dehydration and desulfurization of C9 distillate oil to ensure the quality of raw materials.
2. Polymerization: The pretreated C9 distillate is fed into a polymerization reactor for polymerization under high temperature and high pressure conditions.
3. Post-treatment: After the reaction, the polymer is cooled, cut, packaged and other treatments to obtain the finished resin.

5. equipment selection

In the manufacturing process of C9 petroleum resin, the equipment that needs to be used includes polymerization reactors, agitators, pumps, coolers, etc. In order to ensure production efficiency and product quality, it is necessary to select equipment with stable performance and reliable operation. At the same time, it is also necessary to select the appropriate equipment model and specifications according to the production scale and product characteristics.

6. operating points

In the manufacturing process of C9 petroleum resin, the following operating points need to be paid attention to:

1. Control the temperature and pressure of the polymerization reaction to ensure the smooth progress of the reaction.
2. Maintain and maintain the equipment regularly to ensure the normal operation and service life of the equipment.
3. Strengthen the quality control in the production process, find and solve problems in time, and ensure product quality and production efficiency.

7. safety production and environmental protection requirements

In the manufacturing process of C9 petroleum resin, it is necessary to comply with relevant safety production and environmental protection requirements to ensure the safety and environmental protection of the production process. At the same time, it is also necessary to strengthen the treatment and recycling of waste to reduce the impact on the environment.

8. conclusion

C9 petroleum resin as an important raw material for chemical production has a wide application prospect. Through reasonable raw material selection, reaction principle analysis and process design, high quality and high yield C9 petroleum resin can be produced. At the same time, it is also necessary to pay more attention to equipment selection, operation points, safety production and environmental protection requirements to ensure the smooth progress of the production process and minimize the impact on the environment.
