How to perform analysis and testing of crude oil dehydration effect?
Thread Content
Which kind of demulsifier works best with crude oil will need to be tested to know. Please provide steps and precautions!
Evaluation of different demulsifiers. The water content and salt content of the crude oil before and after treatment were measured, and then the analysis results were summarized and sorted to make judgments based on the data. The specific test method needs to be designed by yourself, such as treatment temperature, oil-water ratio, demulsifier addition amount, dehydration time, electrode voltage (if it is electrical desalination), etc.
The water content of crude oil is definitely the first thing to know: 1. Adjust the temperature of the water bath according to the use temperature requirements of the demulsifier 2. The amount of addition varies from small to large 3. The observation time ranges from 15 to more than 1 hour 4. It's ok to record the time the water comes out of each time.
