Operation optimization method based on refining device operation data

Abstract

The embodiment of the invention provides an operation optimization method based on refining device operation data. The method comprises the steps of determining a data type and a state parameter for constructing a refining device case library; extracting historical operation data of the refining device based on the determined data type according to a preset duration, and performing steady-state detection on the extracted historical operation data in combination with the state parameters; selectively carrying out case extraction according to a steady-state detection result, and screening extracted cases to obtain multiple types of case libraries; and taking the operation data of the refining device based on the determined data type, matching the operation data with the operation data storedin the case library, and outputting an operation optimization suggestion for the refining device according to a matching result. By performing steady-state detection and case extraction on historicaloperation data, the application of historical data is truly realized; and by designing different case library types of multiple targets, the number of the targets can be flexibly increased and decreased, and classified application of historical operation data is realized.

Description

technical field [0001] The invention belongs to the field of chemical process analysis, and in particular relates to an operation optimization method based on operating data of refining and chemical equipment. Background technique [0002] During the operation of refining and chemical equipment, a large amount of operational data has been accumulated, which records and reflects the operational information of the equipment. Using certain means to analyze and organize these data can be used to guide the device to maintain a better working condition in the future operation, and avoid the device being in a poor working condition for a long time in the future operation. [0003] The steps of using the operating data in the prior art are: S1: Set the case structure, and construct the case library according to the case structure, wherein the case structure includes fingerprint information, operation situation evaluation information, and operation parameters to be matched and State...

Problems solved by technology

[0004] From the description of its implementation steps, it can be concluded that the existing process of building a case library does not reflect the analysis and arrangement of device operation data, nor the process of extracting cases from device operation data; at the same time, only one case library is designed, without consideration In the case of multiple targets, when the target changes, it is necessary to rebuild the case library and increase the data processing steps
