The manufacturing method
of diesel
1. Introduction

diesel is a fuel widely used in diesel locomotives, with high calorific value, low viscosity, flammable and explosive characteristics. In the field of raw materials for chemical production, the manufacturing method of diesel oil has attracted much attention. This article will introduce a common diesel manufacturing method.

2. materials and equipment

1. Materials: crude oil, catalyst, hydrogen, etc.
2. Equipment: distillation tower, reactor, fractionation tower, storage tank, etc.

3. manufacturing steps

1. Crude oil pretreatment: crude oil desulfurization, dehydration, desalting and other treatments to ensure the smooth progress of the subsequent processing process.
2. Atmospheric distillation: the pretreated crude oil is subjected to atmospheric distillation to separate gasoline, kerosene, diesel and other fractions.
3. Catalytic cracking: The heavy fraction obtained by atmospheric distillation is subjected to catalytic cracking to generate more light fractions and improve the yield of diesel oil.
4. Hydrotreating: Hydrotreating the diesel oil after catalytic cracking to improve the quality of diesel oil.
5. Fractionation and blending: The hydrotreated diesel is fractionated to obtain diesel products of different grades and blended to meet national standards.

4. precautions

1. Strictly control the reaction conditions, such as temperature, pressure, space velocity, etc., to ensure the smooth progress of the reaction.
2. Check and maintain the equipment regularly to ensure the normal operation of the equipment.
3. Strengthen the monitoring of production process, find and solve problems in time to ensure product quality and production safety.

5. Conclusion The manufacturing method of

diesel involves many process steps and precautions, and it is necessary to strictly control the reaction conditions and equipment operation conditions to ensure product quality and production safety. Through the manufacturing method introduced in this article, high-quality diesel products can be produced to provide reliable fuel for diesel locomotives.
