Embodiment 1

[0069] see image 3 As shown, in the above step S1, the operation data of the refining reaction section of the hydrocracking process is preprocessed, and the specific method for obtaining the steady-state operation data is as follows:

[0070] S11, using the K-mean clustering algorithm to automatically remove outliers in the process operation data;

[0071] S12. According to the different characteristics of the signal and the noise at different time scales, use wavelet denoising technology to remove the noise in the process operation data.

[0072] The K-mean clustering algorithm is used to automatically remove the outliers in the process operation data of the refining reaction section of the hydrocracking process, so as to avoid the interference of abnormal data on the model construction.

[0073] The noise-containing process operation data in the refining reaction section of the hydrocracking process can be eliminated according to the principle that the signal and noise pre...

Abstract

The invention provides a method for optimizing reaction conditions of the hydrocracking process. The method includes the steps that chemical reactions in the hydrocracking process are classified according to the lumping theory, and a kinetic model of a reactor is set up by combining material balance and energy balance principles; further, a state transition algorithm is adopted to correct parameters of the kinetic model, a steady optimizing model is set up based on the corrected reaction kinetic model to optimize inlet temperature of all bed layers of the hydrocracking process reactor on line, and then the purposes of prolonging the operation cycle of equipment and increasing economic benefits of an enterprise are achieved.

Description

technical field [0001] The invention relates to the technical field of crude oil processing, in particular to a method for optimizing reaction conditions in a hydrocracking process. Background technique [0002] In the face of increasingly heavy and inferior petroleum resources and the increasing environmental protection calls worldwide, high-quality diesel oil can be produced by using sulfur-containing nitrogen-containing macromolecular hydrocarbons such as vacuum gas oil VGO, catalytic diesel oil, and wax oil as raw materials The hydrocracking technology of clean fuels such as high-quality aviation kerosene, light / heavy naphtha and liquefied petroleum gas has attracted more and more attention from scientific and technological workers and field engineers. Hydrocracking technology combines the advantages of hydrofining and catalytic cracking two raw oil secondary treatment technologies. It has the advantages of wide range of raw material processing, good quality of end produ...
