【Abstract】 The influence of motionless mixer on gas holdup and dispersed phase holdup in gas-agitating(extraction) tower was studied.The apparent gas velocity,apparent water velocity and apparent oil velocity have some different effects on gas holdup and dispersed phase holdup in the case of gas-liquid-liquid triple phase system under stirring.The apparent gas velocity induce the maximum impacting strength but the minimum for the apparent oil velocity on gas holdup.In the case of dispersed phase holdup,the influence of apparent gas velocity is the strongest and apparent water velocity is the weakest.The type and specification of motionless mixer give some effects on both gas holdup and dispersed phase holdup.The influence factor of typeⅠmotionless mixer on the gas holdup and dispersed phase holdup is much bigger than that of typeⅡunder the same manipulating conditions.更多还原
