摘要:

Using a radiosoptopic tracer to measure the concentration of demulsifiers,we studied the distribution regularity of demulsifiers between crude oil and water phases under different temperatures and found that the dewatering rate is related to the partition coefficient of demulsifier, which is quite sensitive to the variation of temperature According to the experimental results, we hold that an effective demulsifier should possess a relatively high partition coefTicient.
