Ceramics different saddle ring packing is to be improved in the saddle ring packing based on a new type of filler, the filler smooth curved side of the Intalox changed to the convex side of serrated or grain pattern. So packed bed to increase the contact gap between the filler to make it more conducive to the flow of gas and liquid filler layer and diffusion, with a low pressure drop, high mass transfer efficiency, widely used in the production of sulfuric acid drying tower and absorber.
