Problems solved by technology

On the one hand, due to problems such as large amount of data, high noise, and instability, if these raw data are directly processed, the accuracy and reliability may not be guaranteed; on the other hand, the spatial distance method can only measure two groups The distance between the data cannot reflect the trend of the respective data changes

Embodiment 2

[0061] Example 2: The similarity between the quick evaluation data of crude oil and the blending head component tracking data, the similarity between the quick evaluation data of crude oil and the crude oil data of ordinary refining are all less than 80%, and the data of crude oil of ordinary refining can be obtained, and the crude oil of ordinary refining is taken The data is crude oil property data;

Embodiment 3

[0062] Example 3: The similarity between the quick evaluation data of crude oil and the blending head component tracking data, the similarity between the quick evaluation data of crude oil and the crude oil data of ordinary refining are all less than 80%, and the crude oil data of ordinary refining cannot be obtained, so the quick evaluation of crude oil is taken The data is crude oil property data;

Embodiment 4

[0063] Embodiment 4: Crude oil rapid evaluation data cannot be obtained, and component tracking data can be obtained, take component tracking data as crude oil property data;

Abstract

The invention discloses a crude oil property data correcting method which comprises the step of correcting three crude oil property data, that is, crude oil fast assessment data, blend oil component tracking data and normally refined crude oil data within a steady-state time range on the basis of similarity comparison. By correcting the crude oil property data, crude oil property data which are relatively approximate to the true value can be selected for real-time optimization control over a device, and the adverse influence caused by the problems that a near-infrared analyzer for crude oil rapid assessment analysis is insufficient in detection precision and the like can be avoided.

Description

technical field [0001] The invention relates to a method for correcting production process data, in particular to a method for correcting crude oil property data through crude oil similarity calculation before real-time optimization control of an atmospheric and vacuum device. Background technique [0002] Atmospheric and vacuum distillation units are leading units in the petrochemical industry. Through real-time optimization of the unit, the yield of high-value products can be increased and the energy consumption of the unit can be reduced, which is of great significance to the improvement of the economic benefits of the refinery. At present, most refining and chemical enterprises use the rapid evaluation method of crude oil to obtain crude oil property data. Since the detection accuracy of near-infrared analyzers will cause a certain degree of error in the obtained data, in order to select crude oil property data closer to the real value for device optimization, Crude oil ...
