【摘要】 针对高含水原油破乳中广泛采用的热化学法,试验研究了加热温度、加入破乳剂量对破乳效果和破乳速率的影响。试验结果表明,对一定量的原油乳状液,破乳剂用量均在一个最佳值;温度会影响破乳剂的最佳值,随温度升高,原油乳状液破乳时所使用的破乳剂用量的最佳值降低;同时,加入的破乳剂量对乳状液脱水速率也有一定的影响。更多还原

【Abstract】 In consideration of thermochemical method in demulsification of high water-content crude oil,the influences of temperature and quantity of demulsifier on the demulsification efficiency and demulsification velocity were investigated.It is shown that for a fixed amount of crude oil,there is an optimum quantity of demulsifier and it is affected by temperature.The optimal quantity of the demulsifier for crude oil decreases with the increase of temperature.The quantity of demulsifiers can also affect the dehydration velocity of the emulsion.更多还原
