Petroleum products are transformed through chemical reactions to obtain the required components, thereby producing a series of petroleum products that meet standards.
The core process steps of petroleum refining mainly include atmospheric and vacuum distillation, catalytic cracking, delayed coking, hydrocracking, solvent deasphalting, hydrorefining, and catalytic reforming.
1. The main raw materials include: crude oil, etc.
2. After refining, the main products include: naphtha, crude diesel oil (i.e. gas oil), residual oil, asphalt, and first line gasoline.
3. Terminology interpretation:
Atmospheric and vacuum distillation is a key step in the refining process, involving two distillation methods: atmospheric and vacuum distillation. Essentially, this is a physical process in which the feedstock oil is separated into different boiling point oils (called fractions) within a distillation tower based on its evaporation capacity. Some of these oils are directly used as products after blending and adding additives, while the majority are used as raw materials for subsequent processing.
Atmospheric and vacuum distillation is the first process in petroleum processing, also known as the primary processing of crude oil, which includes three main steps: a. Desalination and dehydration treatment of crude oil; b. Atmospheric distillation; c. Vacuum distillation.
4. Overview of Production Process:
Crude oil usually contains salt and moisture, which can cause equipment corrosion. Therefore, before entering the atmospheric and vacuum distillation stage, crude oil needs to undergo desalination and dehydration pretreatment, which is usually achieved by adding demulsifiers and water.
The output proportion of various products is roughly as follows: naphtha (light gasoline or chemical light oil) accounts for about 1%, diesel accounts for about 20%, wax oil accounts for about 30%, residual oil and asphalt account for about 42% in total, and the first line accounts for about 5%.
Here is information about another petroleum refining process:
1. Main raw materials:
2. After processing, the main products include gasoline, diesel, slurry oil (heavy distillate oil), liquid propylene, liquefied gas, etc. The proportion of each product is roughly as follows: gasoline accounts for about 42%, diesel accounts for about 21.5%, propylene accounts for about 5.8%, liquefied gas accounts for about 8%, and slurry oil accounts for about 12%.
