The manufacturing method
of petroleum ether
1. Introduction

Petroleum ether is a common chemical production raw material, widely used in cleaning agents, solvents, extractants and other fields. With the continuous development of the chemical industry, the demand for petroleum ether is also increasing year by year. Therefore, the study of petroleum ether manufacturing methods to improve production efficiency and quality is of great significance to promote the development of the chemical industry.

2. the nature and use of petroleum ether

petroleum ether is a colorless transparent liquid, volatile, flammable and toxic. Its main component is hydrocarbons, according to different boiling point range, can be divided into light petroleum ether and heavy petroleum ether. Petroleum ether has good solubility and drying properties, so it is widely used in chemical, pharmaceutical, food and other fields.

3. Petroleum Ether Manufacturing Method

1. Distillation

distillation method is one of the commonly used methods for the manufacture of petroleum ether. The method is to carry out distillation of crude oil or petroleum fraction, according to different boiling point range, separate different fractions of petroleum ether. The distillation method can be divided into two kinds of atmospheric distillation and vacuum distillation. Atmospheric distillation is suitable for separating light petroleum ethers with lower boiling points, while vacuum distillation is suitable for separating heavy petroleum ethers with higher boiling points. The advantages of distillation method are simple operation and low cost, but the purity of petroleum ether obtained is low.

2. Refining method

Refining method is a method to remove impurities and improve purity by chemical reaction or physical operation of petroleum ether. Commonly used refining methods include acid-base washing, adsorption, distillation, etc. Acid and alkali washing can remove acidic or alkaline impurities in petroleum ether, adsorption method can use the adsorption effect of adsorbent to remove impurities, and distillation method can separate different boiling point components to obtain higher purity petroleum ether. The advantage of the refining method is that petroleum ether with higher purity can be obtained, but the operation is more complicated and the cost is higher.

4. petroleum ether manufacturing process

petroleum ether manufacturing process mainly includes raw material pretreatment, distillation, refining and other steps. The specific process is as follows:

1. Raw material pretreatment: crude oil or petroleum fractions are desalted, dehydrated and other treatments to ensure the smooth progress of subsequent processes.

2. Distillation: Distillation of the pretreated feedstock to separate different fractions of petroleum ether.

3. Refining: Refining the petroleum ether obtained by distillation to remove impurities and improve purity.

4. Finished product inspection: the quality inspection of the petroleum ether can be carried out before delivery.

5. of petroleum ether in the manufacturing process of

1. the operation process should pay attention to safety, avoid the occurrence of fire and explosion accidents.

2. For different boiling point of petroleum ether, according to different process requirements for operation, in order to ensure product quality.

3. In the refining process, it is necessary to select the appropriate refining methods and operating conditions to ensure product purity and yield.

6. conclusion

petroleum ether is an important raw material for chemical production, and its manufacturing method is of great significance to improve product quality and production efficiency. In the actual production process, it is necessary to select the appropriate manufacturing method and operation process according to different process requirements and raw material properties to ensure product quality and production safety. At the same time, with the continuous development of chemical technology, the manufacturing method of petroleum ether also needs to be constantly updated and improved to meet market demand and improve production efficiency.
