Method for improving reaction and generation efficiency in petroleum refining

Abstract

The invention discloses a method based on improving the recovery efficiency of the petroleum refining process. The mixed wax oil and the atmospheric residual oil are respectively sent from the raw material tank of the tank farm to the static mixer in the device and mixed evenly, then enter the raw material buffer tank, and then Pump it out with a raw material pump, pass through the flow control valve, return to exchange heat, and then exchange heat with oil slurry to 170-220°C, and enter the static mixer together with the refined oil to mix evenly. Together, they enter the riser through six feed nozzles, contact with the high-temperature regenerated catalyst from the second secondary, and immediately vaporize, crack into light products and generate 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 precision of refining, and improves the utilization rate of oil.

Description

technical field [0001] The invention relates to the field of petroleum processing, in particular to a method based on improving the reverse recovery efficiency of the petroleum 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%), hydrog...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problems that the above-mentioned existing petroleum refining process does not strictly control the temperature and refining process, so that there are many impurities, the refining precision is poor, and the waste rate of petroleum is high. The method of process anti-re-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 and The refining process is not strictly controlled, resulting in many impurities, poor refining precision, and high waste rate of oil
