Catalytic cracking method: Process the atmospheric and vacuum distillates at 460–530°C and a pressure of 1–2 kg/cm².
Delayed coking: A process that involves extending the residence time of heavy oil under high temperature and pressure, causing it to undergo extensive cracking into gases, liquids, and coke.
Delayed coking: A process that involves extending the residence time of heavy oil under high temperature and pressure, causing it to undergo extensive cracking into gases, liquids, and petroleum coke.
Hydrotreating: A process that uses a catalyst to react heavy oils or certain fractions with hydrogen under high temperature and pressure, removing impurities such as sulfur, nitrogen, and oxygen, thereby improving the properties of the final product.
Intelligent oil refining:
The intelligentization of petroleum refining processes involves leveraging information technology, automation technology, artificial intelligence technologies, and more, to achieve data collection, analysis, optimization, and control throughout the petroleum refining workflow—thereby enhancing efficiency, quality, and safety in oil refining. This encompasses areas such as intelligent crude oil management, smart control of refining equipment, advanced quality assurance for refined products, and integrated, intelligent management practices within refining enterprises.
Petroleum refining business sector:
The petroleum refining business sector also encompasses supporting technologies such as clean gasoline and kerosene production techniques, diesel fuel production technology, processing technologies for low-quality and heavy crude oils, petrochemical integration methods, natural gas-to-transportation-fuel processes, and petrochemical feedstock technologies.
In short, petroleum refining is a complex and meticulous process that involves a variety of technologies and methods, aimed at extracting diverse, useful petroleum products from crude oil.
