Reaction and regeneration process for improving oil refining efficiency in petroleum refining process

Abstract

The invention discloses an anti-reprocessing process for improving oil refining efficiency in the process of oil refining. Mixed wax oil and atmospheric residual oil are respectively fed into a static mixer in a device from a raw material tank in a tank farm and mixed evenly, and then enter a raw material buffer tank. Then use the raw material pump to pump out, pass through the flow control valve, return to heat exchange, and then exchange heat with the oil slurry to 170-220 ° C, and enter the static mixer together with the refined oil to mix evenly. The steam enters the riser through six feed nozzles, contacts with the high-temperature regenerated catalyst from the secondary stage and immediately vaporizes, cracks into light products and generates oil slurry, dry gas and coke. The process strictly controls the reaction and regeneration process, so that the obtained product meets the quality, improves the refining precision, and improves the utilization rate of oil.

Description

technical field [0001] The invention relates to the field of oil processing, in particular to an anti-reprocessing process for improving oil refining efficiency in the oil refining process. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown (sometimes greenish) liquid. There are oil reserves in parts of the upper crust. It is composed of a mixture of different hydrocarbons, and its main component is alkanes. In addition, petroleum also contains elements such as sulfur, oxygen, nitrogen, phosphorus, and vanadium. Petroleum is mainly used as fuel oil and gasoline, which constitute one of the most important primary energy sources in the world. Petroleum is also a raw material for many chemical industry products such as solutions, fertilizers, pesticides and plastics. Oil is mostly hydrocarbons. It is composed of a mixture of different hydrocarbons. The chemical elements that make up petroleum are mainly carbon (83% ~ 87%), hydrogen (1...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above problems that the existing petroleum refining process does not strictly control the temperature and refining process, resulting in many impurities, poor refining precision, and high waste rate of petroleum, and designs a petroleum refining process. The anti-reprocessing process to improve the refining efficiency, which strictly controls the reaction and regeneration process, makes the obtained products meet the quality, improves the refining precision, improves the utilization rate of oil, and solves the problem of temperature in the existing oil refining process. And the refining process is not strictly controlled, resulting in many impurities, poor refining precision, and high waste rate of oil
