Example Embodiment

[0035] The present invention will be further described below with reference to the drawings and embodiments.

[0036] Near infrared technology (NIR) is a non-destructive, fast, accurate, and simple analysis technology developed after the 1970s. It is widely used in the qualitative and quantitative analysis of agricultural products, food, medicine and chemical products. In the near-infrared spectroscopy, there are vibrational combined frequency and doubled frequency absorption. The near-infrared spectroscopy can be used to analyze the moisture content in crude oil.

[0037] Such as figure 1 As shown, the near-infrared-based crude oil water content measurement device includes a bypass branch device 2 connected to the crude oil main pipeline 1 of the crude oil to be tested, and the crude oil main pipeline 1 is used to allow crude oil to flow through; The bypass branch pipe in the branch pipe device 2 communicates with the crude oil main pipeline 1; the bypass branch pipe device 2 includ

Abstract

The invention discloses a crude oil moisture content measuring device and measuring method based on near infrared. The method comprises the step: connecting a bypass branch pipe device to a crude oilmain pipeline of measured crude oil, and using the crude oil main pipeline for allowing the crude oil to flow through. The bypass branch pipe device comprises a bypass branch pipe and measuring equipment communicated with the bypass branch pipe and the bypass branch pipe is communicated with a crude oil main pipeline; and the bypass branch pipe device is used for collecting and measuring crude oil. The measuring equipment comprises a crude oil collector, and the crude oil collector has a tank-shaped structure communicated with the bypass branch pipe. after combining of the method, the defectsof insufficient sensitivity and very low precision of a dynamic detection method for the water content of crude oil in the prior art are effectively overcome.
