Description

Technical Field

[0001] The utility model relates to the technical field of demulsifier detection, in particular to a demulsifier dissolution performance detection device. Background Technique

[0002] A demulsifier is a non-ionic surfactant used for dehydration, which can remove the water in crude oil and heavy oil to meet the water content requirement; it can be used in oil wells to reduce the viscosity of crude oil and prevent the oil wells from being blocked. It has a soapy smell. Since some solids are insoluble in water, when one or several of these solids are present in large amounts in an aqueous solution, under the agitation of hydraulic or external power, these solids can exist in the water in an emulsified state, forming an emulsion. In this case, by adding a demulsifier, the stable double electric layer structure and the stable emulsion system can be destroyed, so as to achieve the purpose of two-phase separation and the effect of destroying emulsification.

The bottle mouth of the volumetric bottle body is wedge-shaped, there are cast-in scales on the wall of the volumetric bottle body, and two identical sampling tubes are connected at a certain height on the wall of the volumetric bottle body. Sampling valves are equipped on the sampling tubes, and the valve plugs of the sampling valves are columnar with round holes in the center. The utility model has the following advantages: simple structure, convenient operation, and can accurately take out the upper, middle and lower layer oil samples after dehydration at any time.
