The manufacturing method
of kerosene
kerosene is a widely used raw material for chemical production, mainly used in combustion, solvent and precision mechanical lubrication. The manufacturing method of kerosene mainly includes distillation, refining and blending steps. This article will introduce the manufacturing method of kerosene in detail.

1. raw material preparation

kerosene manufacturing raw material is mainly petroleum, through the distillation of petroleum, to obtain different boiling point of hydrocarbon mixture. In order to produce high quality kerosene, it is necessary to select high-quality crude oil with low sulfur, low nitrogen and low metal content as raw materials.

2. Distillation

distillation is the core step of kerosene manufacturing, which separates crude oil into components with different boiling points by heating and condensing. The distillation process is generally carried out at atmospheric and reduced pressures to obtain a suitable boiling range. During the distillation process, temperature and pressure need to be controlled to ensure product quality and yield.

3. Refining

The crude kerosene obtained by distillation contains impurities, such as sulfides, nitrides, gums, etc., which need to be removed through the refining process. Refining methods include acid and alkali washing, adsorption, oxidation, etc., to ensure the quality and stability of kerosene products.

4. blending and

In order to meet the needs of different fields, kerosene products need to have certain performance indicators. Therefore, it is necessary to adjust the properties such as density, viscosity and flash point of the refined kerosene. In the process of reconciliation, it is necessary to strictly control the indicators to ensure that the product quality meets the standards.

5. storage and transportation

manufactured kerosene needs to be stored in special storage tanks to avoid direct sunlight and high temperature environment. In the process of transportation, the appropriate mode of transportation should be selected to ensure the safe delivery of products to the destination.

In short, the manufacturing method of kerosene involves multiple links, and it is necessary to strictly control factors such as raw material quality, distillation conditions, refining process and blending ratio to ensure product quality and yield. At the same time, it is also necessary to strengthen safety management during storage and transportation to avoid accidents.
