基于正交实验的老化油超声脱水机理
Mechanism of ultrasonic dehydration of aging oil based on orthogonal experiments
摘要
Abstract
By using ultrasound to treat aged oil,the optimal ultrasound conditions for demulsification and dehydration of aged oil were analyzed through orthogonal experiments,and SEM and particle size analysis were used to characterize the aged oil before and after ultrasound treatment.The experimental results show that the order of the influencing factors of aging oil demulsification and dehydration is ultrasonic power>ultrasonic action mode>ultrasonic action time.The optimal conditions are ultrasonic power 520 W,ultrasonic action time 3 min,and ultrasonic work 6 s and stop 1 s.Under these conditions,the dehydration rate of aging oil can reach 34.50%,the droplets are more regular with simple ingredients,and the oil-water interfacial film becomes thinner.When ultrasonic cavitation acts on aged oil,demulsification and emulsification may occur simultaneously,with demulsification being the dominant factor under certain power conditions and emulsification being the dominant factor under other power conditions.关键词
