Abstract

The invention discloses a crude oil blending optimization method, which supports minimum deviation of property and content of blended crude oil to target oil for crude oil manufacturers, namely under certain constraint conditions, percentages of various blended crude oils are obtained by minimization using a deviation function for related properties and contents of the blended crude oils and the set target. For safety and economy, the method further supports three optimization ways for property and content of the crude oil, namely in-range characterization, lower limit oriented optimization and upper limit oriented optimization. The method further supports economic optimization of targets, namely the minimum deviation between property and content of the blended crude oil and the targets is considered, and minimization of production cost is achieved. By the method, blending percentages of the crude oils are automatically generated and downloaded to a control system for execution, the crude oils meeting processing requirements are provided for CDUs (central distillation units), damage of the CDUs and subsequent processing devices due to property change of the crude oils is avoided, production efficiency and economic benefit are improved, and the method is especially applicable to crude oil processing in oil refinery.

Description

technical field

[0001] The invention relates to the field of crude oil processing in oil refining enterprises, in particular to an optimization method for crude oil blending. Background technique

[0002] At present, in the petroleum and petrochemical industries, refined oil (such as gasoline, diesel) blending optimization technology has been widely used, but the blending optimization technology has not been used in crude oil processing. Atmospheric and vacuum unit (CDU) is the first link of crude oil processing. CDU has strict requirements on the properties and content of crude oil (such as sulfur content and acid content) in production. Crude oil processing enterprises currently widely use manual blending methods. Calculating the proportion of each blended crude oil, the proportioning amount is often not optimal, resulting in problems such as large production fluctuations and poor returns. Contents of the invention

[0003] The purpose of the present invention is to pro...
