Embodiment Construction

[0024] The present invention will be further described below in conjunction with drawings and embodiments.

[0025] In the following, the detailed calculation process and specific operation flow are given based on the actual implementation of the present invention in a certain refining and chemical enterprise and combined with a specific calculation example.

[0026] Such as figure 1 As shown, the enterprise has 3 crude oil component tanks and 3 crude oil blending lines, and each crude oil blending line uses a blending component tank. After being blended by the pipeline blending head, it goes through the buffer tank and finally sent to the CDU for processing. The blending is carried out in batches, and a certain total amount is blended in each batch, and the next batch is blended after the blending of this batch is completed. This embodiment is implemented on the premise of the technical solution of the present invention, but the protection scope of the present invention is ...

Abstract

Disclosed is a crude oil blending optimization method with the deviation correction function of a base oil property. The method is about a crude oil blending production process and comprises the steps that component oil in component tanks is blended at blending ends, passes through a buffer tank filled with base oil and is fed into an atmospheric and vacuum plant to be processed. Blending is carried out aiming at base oil property deviation correction and lowest blending cost, the problem of deviation compensation of the buffer-tank base oil property when crude oil is blended is solved, crude oil meeting the processing requirement is provided for a CDU, damage to the CDU and subsequent processing devices by the property deviation of the crude oil is avoided, product quality is ensured, and economic benefits of enterprises are improved.

Description

technical field [0001] The invention relates to the field of crude oil processing in oil refining enterprises, in particular to a method for optimizing crude oil blending with base oil property correction. Background technique [0002] At present, the online automatic blending technology of crude oil has begun to be successfully applied in many domestic refineries. Online automatic blending of crude oil often adopts pipeline blending, that is, after blending in the pipeline blending head, it is directly sent to the atmospheric and vacuum unit, namely CDU, for processing. However, there is also such a situation in some enterprises, that is, the component oils are first blended in the blending head, and then sent to the CDU for processing through the buffer tank. [0003] The existing online formula optimization methods for crude oil blending are often aimed at the blending head product rather than the tank product. When there is no bottom oil in the buffer tank, controlling...
