Plastic Super Intalox Ring was one improved ring based on Intalox ring’s structure. The biggest improvement is that Plastic Super Intalox saddle’s arc profile will be change wavy or jagged profile. meanwhile, increase some pores in the arc liquid channel’s middle position. This structure’s change not only increase packing’s contacting gap, but also improve gas & liquid’s movement and distribution in packing layer.Plastic super intalox ring channel is like Open Semi-Round or Arc Type. It is not speed up air & liquid movement and contacting, but also decrease movement resistance. However, Open Semi-round or Arc Type also caused Plastic Super intalox saddle’s overlapping and interweaving. Instead, it will lead to a decrease in mass transfer efficiency.Further, it is less sensitive to liquid distribution quality and has higher liquid hold-up and residence time for those services that benefit from such characteristics.
