1. The first process of crude oil processing: The atmospheric and vacuum distillation unit is the first process of crude oil processing, which divides crude oil into different boiling point ranges of oil products or semi-finished products through heating and distillation. The main separated products include reforming feedstock, gasoline components, aviation kerosene, diesel, lubricating oil, catalytic cracking feedstock, etc
2. Separation of crude oil: In the atmospheric tower, crude oil undergoes distillation process, and the gas-liquid phase fully realizes heat exchange and mass exchange. Products with lower boiling points such as gasoline are distilled from the top of the tower, heavy oil with higher boiling points is distilled from the bottom of the tower, and side products such as kerosene and diesel are extracted from the middle of the tower
3. Energy saving technology: Atmospheric and vacuum distillation units account for a large proportion of the overall energy consumption in refineries, usually exceeding 25%. By recycling waste heat from flue gas, optimizing energy conversion and transmission, and other measures, energy consumption can be effectively reduced and the operating efficiency of the device can be improved.
4. Environmental protection measures: In the process of vacuum distillation, a dry vacuum system is used instead of traditional steam injectors to improve operating efficiency, reduce energy consumption and exhaust emissions, and achieve a green and safe production environment
