Study on mechanism of on-line monitoring of water content in oil
Analyzed the properties changes under the condition of different water content and its on-line /off-line detecting methods from the aspect of its research and development at home and abroad,and then proposed a new on-line monitoring method based on the influencing rule of oil's key characteristics by different water content. This new method would firstly establish a fuzzy identifying mathematical relation between oil physicochemical indexes and water content,and secondly set up a mathematical model between dynamic characteristics and physicochemical indexes of oil,and then monitor the dynamic characteristics of oil by sensor and calculate the water content through the model. Compared with other on-line monitoring method,this method breakthrough the limit that only single physicochemical index can be used in the detecting model,which will make the detection result more efficient and accurate.
