Abstract

The invention relates to an on-line measure apparatus for water content and density and a measure method thereof. The measure apparatus comprises a water analyzer, a densitometer, a host computer, a controller, a measure pipe and an automatic sampling device; the host computer is connected with the controller, the water analyzer, the densitometer and the automatic sampling device; the controller is connected with the water analyzer, the densitometer and the automatic sampling device; the automatic sampling device, the water analyzer and the densitometer are all installed on the measure pipe; and the water analyzer and the densitometer are arranged on the measure pipe, the automatic sampling device is arranged at the lateral side of the measure pipe, the water analyzer and the densitometer are arranged oppositely, and the automatic sampling device is opposite to the water analyzer and the densitometer and is arranged between the water analyzer and the densitometer. The apparatus is capable of realizing on-line real-time measure on an oil product and automatic sampling and storing a sample, helps to effectively solve the quality control problem of the oil product during transportation and comprehensively monitor the characteristics of the oil product, and is applicable in fields such as tank cars, pipelines, ship oil discharging and the like.

Description

technical field [0001] The invention relates to the technical field of oil-water monitoring, in particular to an on-line measuring device for water content and density and a measuring method thereof for oil quality monitoring. Background technique [0002] In pipeline oil transportation, ship unloading, tank truck unloading and other links, it is necessary to monitor the quality of oil in real time to ensure the quality of oil transportation. At present, the oil product monitoring of the above-mentioned links mainly adopts the method of manual sampling and manual testing to determine the quality of the oil product. With the development of electronic detection technology, water content analyzers are gradually used instead of manual testing to monitor the water content in the medium oil. Thus, it plays a warning role, and thus prevents the occurrence of phenomena that affect oil quality such as water mixing and dark tanks; In the scene where inferior oil is mixed, the water c...

At present, the oil product monitoring of the above-mentioned links mainly adopts the method of manual sampling and manual testing to determine the quality of the oil product. With the development of electronic detection technology, water content analyzers are gradually used instead of manual testing to monitor the water content in the medium oil. Thus, it plays a warning role, and thus prevents the occurrence of phenomena that affect oil quality such as water mixing and dark tanks; In the scene where inferior oil is mixed, the water content analyzer cannot perform the monitoring function and cannot play a warning role, resulting in great losses for relevant users

[0003] For the testing of oil products, the two parameters of water content and density are mainly tested. The testing of water content mainly includes gravity separation method, distillation method, centrifugal separation method, etc. Among them, distillation method is the most widely used method at present. Its advantages The test is accurate, the data is reliable, and the precision of the operation test according to the national standard is very high. The disadvantage is that it takes a long time to test each sample, and it is impossible to monitor the water content of the oil in real time.

For the density test of oil products, the existing technology also has the defect of not being able to achieve real-time monitoring

Therefore, the staff in charge of monitoring and controlling different parameters often shirk their responsibilities after oil quality monitoring problems occur. Finalize the root cause of the problem
