Most of the water in the crude oil contains salts, which will accelerate the corrosion of equipment, pipelines and pipelines. In the process of oil refining, when water and crude oil are heated together, the water will rapidly vaporize and expand, the pressure will rise, which will affect the normal operation of the refinery and the product quality, and even an explosion may occur. Therefore, before the crude oil is transported, dehydration is required to make the water content in the crude oil not more than 0.5%. In the prior art, the water content in the crude oil is generally tested by using a testing device, such as the crude oil water content determination device with the application number 201810084891.1.
