Problems solved by technology

The patent is static blending. The components are pumped out from the component tank by the blending pump and then sent to the blending head after being pressurized. The flow control is set in the pipeline before the components enter the blending head. The flow adjustment range is small and the pressure is not balanced.

Embodiment Construction

[0028] Such as figure 1 Shown is a schematic diagram of on-line blending of three component oils from the production unit.

[0029] From the three component oils from the first component oil production unit 1, the second component oil production unit 9 and the third component oil production unit 15, after the online analyzer carries out quality analysis, the component oil quality analysis results Input the blending computer, and the blending computer adjusts the first component oil regulating valve 6, the second component oil regulating valve 14 and the third component oil regulating valve 20 according to the product oil quality requirements and the analysis results of each component oil quality The opening degree controls the flow of the first component oil, the second component oil and the third component oil into the mixer respectively, enters the static mixer 7, and enters the finished oil storage tank 8 after being fully mixed, and the remaining components from the produc...

Abstract

The invention discloses an online oil product blending method and device. Component oil from a production device is subjected to quality analysis through an online analyzer; quality analysis results of the component oil are input in a blending computer; according to quality requirements of refined oil products and the quality analysis results of various component oil, the blending computer adjusts the opening degree of a component oil adjustable valve; and the adjustable valve controls one part of component oil flow to enter a mixer to be mixed and then enter a refined oil product storage tank and controls the other part of component oil to enter respective component oil storage tanks.

Description

[0001] technology field. [0002] The invention relates to a method for blending oil products, in particular to an online blending method and device for oil products. Background technique [0003] Petroleum refining is an important production area of ​​the petrochemical industry. Crude oil is refined into component oils of different distillation ranges through the refining of petroleum refining production units in the refinery. Most of the component oils extracted by the production equipment cannot be directly sold as refined oil products, because various grades of refined oil have very clear quality index requirements, but the component oils produced from the production equipment are often not It does not fully meet the quality index requirements of a certain refined oil brand. In most cases, some quality indicators do not meet the requirements, while other quality indicators may be a lot richer. In order to fully meet the quality index requirements of refined oil, the gen...
