Project introduction: As the world's energy problems become increasingly serious, the crude oil market and refined oil market are unpredictable, and the quality and price of crude oil have become important factors for the world's refining industry to choose to refine crude oil. Atmospheric and vacuum distillation units are the primary production link of the entire refining industry. Among them, primary distillation towers, atmospheric towers and vacuum towers are key equipment of atmospheric and vacuum distillation units and are responsible for completing the main process of primary crude oil processing. Atmospheric and vacuum distillation units directly process crude oil, cut crude oil into various fractions and consume a large amount of energy. These distillate products are either used as feeds for subsequent sections or sold as refined oils after blending, and have certain quality requirements. Faced with frequent changes in refined crude oil and differences in the nature of refined crude oil, the production of atmospheric and vacuum units can only be adjusted by operators based on experience. Compared with the world's advanced technology, the original technology generally has high processing costs, problems such as high energy consumption and low productivity.

Main features: This technology simulates the process of the atmospheric and vacuum unit to establish a model of the atmospheric and vacuum unit that conforms to the actual industrial unit conditions. According to the different properties of refined crude oil and the quality requirements of distillate products, the optimal operating parameters of the atmospheric and vacuum unit can be found through the model., guide the operator to optimize the operating conditions of the atmospheric and vacuum unit, so that the atmospheric and vacuum unit can be able to operate under the optimal operating conditions according to the different properties of refined crude oil and the quality requirements of distillate products Achieve the optimization goal of reducing production costs and device energy consumption and increasing the output of naphtha products with high added value.

Technical level: The technology is at the leading level in China.

Application prospect: Mainly used in the petrochemical field.
