【Abstract】 A new type and high efficient mass transfer equipment——fiber film contactor is introduced. There are numerous metal fibers in the contactor, and surface tension causes the caustic to cling to the metal fibers, and oil phase flows more freely. As a result, the interfacial area produced while the two phases flow down along the fibers is extremely large, and no emulsions will form. This avoids the separation difficulties of dispersive phase in the conventional method. Hence, no longer are large equipment size and long time of phase separation are needed and a higher mass transfer efficiency is obtained. It has been practically testified that the equipment can preferable improve refiner efficiency.更多还原
