Embodiment

[0081] An on-line water content monitoring method for multi-component oil products, through the automatic zeroing technology and the use of density segmentation correction method, the crude oil density with a wide range of fluctuations is divided into several sub-density intervals, and each sub-density interval has its own deviation correction Coefficient; automatically find the corresponding sub-density interval through the oil density value, and call the correction deviation coefficient of different sub-density intervals according to the different density values ​​to eliminate the influence of oil component changes and oil-water distribution forms on the measurement results , to ensure the accuracy of the moisture content value obtained under ultra-low moisture content.

[0082] figure 1 and figure 2 This is the graph of measurement results obtained after applying the above method to two sites of Zhenhai Refining and Chemical Company, figure 1 The density of medium and pu...

Abstract

The invention belongs to the technical field of crude oil moisture content detection, and relates to a density segmented correction method and an online moisture content monitoring method for online moisture content analysis of a multi-component oil product. The density segmented correction method for online moisture content analysis of the multi-component oil product, which is provided by the invention, comprises: eliminating influence of oil water distribution patterns or different viscosities of oil products on a measurement result in a density segmented correction mode so as to obtain an accurate moisture content value. The methods disclosed by the invention are novel and unique, simple and easy to operate, utilizes the density segmented correction mode to eliminate influence of component variations and the oil water distribution patterns on the measurement result, obtains the high-performance measured value and ensures industrial application of online moisture content analysis ofthe crude oil, i.e., according to the invention, high performance of an online moisture content analyzer under ultra-low moisture content can be ensured.

Description

technical field [0001] The invention belongs to the technical field of water content detection of crude oil, and relates to a density segment correction method for online water content analysis of multi-component oil products and an online water content monitoring method. Background technique [0002] With the rapid development of my country's economy, the demand for oil is also increasing. Among them, the water content of crude oil is an important parameter in the petrochemical industry, and the detection of the water content of crude oil is a common concern in the processes of crude oil extraction, dehydration, processing, gathering and transportation measurement, storage, transportation and sales, and petroleum refining. In the past two decades, my country's oil refining industry represented by Sinopec has long relied on imported crude oil to maintain production. The origin and batch are different, and the quality is different, resulting in a very large change in the comp...
