Abstract
In existing structured packing, performance depends on effective contacting area. Performance decreases in cases having high surface tensions such mixtures containing a lot of water. Such mixtures are difficult to wet the packing surface. The present invention prevents liquid from intersecting the crease of the corrugation and from falling into a free space. Further, liquid flowing into the slot makes frequent liquid and vapor interfacial update resulting in positive utilization of the wetted area. The most important point of this invention is taking a positive utilization of the wetted area. The most important point of this invention is taking a large value of 3.5 or more of P/H (pitch/height of the crimp) and providing the horizontal slot on the crease, resulting in adding the flow reversal mechanism and frequent interfacial update.
