Problems solved by technology

[0005] However, after our in-depth research and experiments, we found that if the samples sent from the sampling device are not subjected to standardized pretreatment, and then directly enter the near-infrared online analyzer, then there will be large errors in the obtained analytical data
The collected samples will affect the near-infrared light transmittance and other indicators due to the different moisture content, impurities or temperature, which will make it difficult to maintain the quality of the blended refined oil from the beginning to the end, which will affect the production efficiency and economy. benefit

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] As shown in Figure 1, the sample passes through the sampling fast loop from the component loop, and is shunted from the fast loop to the pretreatment system.

[0024] After the sample flows into the pretreatment system, it passes through the pressure reducing valve to reduce the pressure of the oil sample for the safe use of the pretreatment system.

[0025] The first constant temperature in the constant temperature device uses a water area. After the sample pipeline passes through this water area, it can fully perform heat exchange, so that the sample temperature can basically reach a certain value, so that the secondary constant temperature device can quickly make the sample reach the predetermined temperature. After constant temperature, the stability and accuracy of the sample analysis results are improved. The effect of constant temperature can ma...

Abstract

This invention provides an oil-product on-line optimized mixing method including a basic control system controlling flow of each component and an optimized control system with intelligent operation connecting to it via an interface, a sample device and a near infrared on-line analyzer analyzing the sample characterizing in including the following technological steps: before analyzing the sample by the near infrared on-line analyzer, the sample is pre-processed including a constant temperature process and water remove process. The invention also provides an oil-product on-line optimized mixing system.

Description

technical field [0001] The invention relates to a process technology for on-line optimization blending of oil products. Specifically, after semi-finished gasoline or diesel oil products flow out from a distillation outlet, the process technology can be used to blend various grades of refined oil products in a pipeline. The invention particularly relates to a method for online optimal blending of oil products, and an online optimal blending system for oil products implementing the method. Background technique [0002] With the advancement of technology, in order to meet the quality standards of optimal blending as much as possible, and meet the needs of maximizing production efficiency and benefits, advanced online blending systems have been adopted by some oil production companies in the world. The online blending system eliminates the past tank blending method, reduces intermediate links, and greatly reduces production costs. The device setting of the online blending syste...
