Petroleum coke manufacturing method

1. overview

Petroleum coke is an important chemical raw material, widely used in metallurgy, chemical industry, electric power and other fields. It is made of petroleum as raw material, through high temperature cracking, carbonization and other processes, with high calorific value, low sulfur, low ash and other advantages. This paper will introduce the manufacturing method of petroleum coke in detail, including the selection of raw materials, production process, equipment selection and so on.

2. raw material selection

manufacturing petroleum coke raw material is mainly petroleum residue, in which the content of asphaltene and colloid is higher, with high cohesiveness and coking. In order to ensure the quality and output of petroleum coke, it is necessary to select suitable raw materials and carry out strict quality control.

3. production process
The production process of
petroleum coke mainly includes the following steps:

1. Raw material pretreatment: dewatering and desalting the petroleum residue to ensure the smooth progress of the subsequent process.

2. high temperature cracking: the pretreated raw material is heated to high temperature to make it undergo cracking reaction to generate oil, gas and coke.

3. Coke cooling: The resulting coke is cooled to reduce its temperature and moisture content for subsequent processing and storage.

4. Screening and packaging: The cooled coke is screened, classified according to different particle sizes, and packaged.

4. equipment selection

In the production process of petroleum coke, it is necessary to use heating furnace, cracking furnace, cooler, screening machine and other equipment. In order to ensure the smooth progress of production and the stability of product quality, it is necessary to select suitable equipment and carry out regular maintenance and maintenance.
Precautions for
5. production

In the production process of petroleum coke, the following matters need to be paid attention to:

1. Strictly control the quality and ratio of raw materials to ensure stable product quality.

2. Strengthen the control of temperature, pressure and other parameters in the production process to prevent safety accidents.

3. Regularly inspect and maintain the equipment to ensure the normal operation of the equipment.

4. Strengthen production site management to keep the environment clean and hygienic.

6. Product Quality Control

In order to ensure the product quality of petroleum coke, strict quality control is required, including the following aspects:

1. Carbon content of coke: the higher the carbon content of petroleum coke, the higher the calorific value, so it is necessary to strictly control the carbon content within the specified range.

2. Ash and sulfur: Ash and sulfur are important indicators for evaluating the quality of petroleum coke and need to be controlled within the specified range to ensure the safety and economy of the subsequent processing and use process.

3. Particle size and strength: Petroleum coke with different particle size and strength is suitable for different application fields, so it needs to be screened and classified according to customer needs.

of environmental protection and sustainable development in

7. With the continuous improvement of environmental awareness and the popularity of sustainable development strategies, the production of petroleum coke also needs to consider environmental protection and sustainable development issues. In the production process, it is necessary to strengthen the treatment and recycling of pollutants such as waste gas and waste water, reduce energy consumption and resource consumption, and improve production efficiency and economic benefits. At the same time, it is also necessary to actively explore new production processes and technologies to promote the upgrading and development of the petroleum coke industry.

In short, the manufacturing method of petroleum coke involves many aspects and precautions, which need to be operated and managed in strict accordance with the production process and equipment selection requirements to ensure product quality and production safety. At the same time, it is also necessary to strengthen the awareness of environmental protection and sustainable development to promote the healthy development of the petroleum coke industry.
