Description

Technical Field

[0001] The utility model relates to the technical field of demulsifiers, in particular to a visual demulsifier evaluation device. Background Art

[0002] Before the offshore crude oil demulsifier is used on site, it usually needs to go through two processes: bottle test screening and field pilot test. Only the excellent demulsifier that has passed the bottle test screening and field pilot test can be used on the offshore oil field site.

[0003] When conducting bottle test screening of demulsifiers, the general process of demulsifier performance evaluation is as follows: place the dehydration test bottle containing the crude oil emulsion sample in a constant temperature water bath for preheating, so that the temperature of the emulsion in the dehydration test bottle rises to the preset dehydration temperature; use a liquid dispenser to add a certain amount of demulsifier to the dehydration test bottle, and oscillate it for a certain time and number of times by mechanical or artificial oscillation; place the dehydration test bottle in a constant temperature water bath and let it settle, and observe and record the dehydration amount, oil-water interface and lower water color at regular intervals.

[0004] Since the dehydration amount, oil-water interface and lower water color of crude oil emulsion are instantaneous during the demulsification and dehydration process, the experimental phenomena such as the dehydration amount, oil-water interface and lower water color are instantaneous. When evaluating the performance of demulsifiers, the experimenters usually take out each dehydration test bottle from the water bath in turn at a certain time interval and observe them. After observing the dehydration amount, oil-water interface and lower water color, they put them into the constant temperature water bath again. This operation needs to be repeated when recording the experimental phenomena. Repeatedly taking out the dehydration test bottle for observation will easily shake the bottle body, and when the emulsified crude oil is light crude oil, its demulsification and dehydration process often changes rapidly within 10 minutes. If there are too many dehydration test bottles, it is difficult to observe the experimental phenomena in each dehydration test bottle in parallel at the same time, making the experimental phenomenon record inaccurate. When the oil-water interface in the dehydration test bottle is not clear, it is also difficult to accurately observe the dehydration amount, oil-water interface and lower water color, and lighting equipment must be used to assist.
