Simulation study on resonant cavity perturbation method to detectmoisture content of crude oil
摘要
Abstract
In comparison with the traditional on⁃line detecting method of moisture content of crude oil,the high⁃frequency microwave resonant cavity perturbation method is seldom influenced by the external environment and never influenced by the mineralization,and has high detecting accuracy. Since the permittivity of water and crude oil is significantly different,and the small change of water content can change the permittivity greatly,the crude oil with different moisture contents may result in the different losses of microwave field. The change of resonant frequency and quality factor of the microwave resonant cavity contain⁃ing perturbation source (sample crude oil) are detected by means of software simulation. The permittivity of sample crude oil can be obtained according the perturbation formula of rectangle resonant cavity. And then the obtained result is substituted into the relation formula reflecting crude oil moisture content and permittivity to get the permittivity of the sample moisture content of crude oil. The crude oil permittivity data detected in aluminum and copper boundary conditions is analyzed with the theoretical value,and the relative percentage error is found out. A simple,practical,fast and accurate method to detect the crude oil with medium and low moisture content is obtained.关键词
