Cascade Mini Ring for short, a lower aspect ratio increases capacity and reduces pressure drop and the highly exposed internal and external surfaces give a high efficiency vehicle for liquid – gas contact with good mechanical strength.Lower aspect ratio increase capacity and reduces pressure drop; its preferential orientation in a packed bed with the cylindrical axis in the vertical plane, allows a free passage for gas to flow through it. Smaller column size without sacrificing the efficiency. The lower pressure drop and higher throughput of ring enables a smaller column diameter and fan size to be specified in new installations,the highly exposed internal and external surfaces provide an efficient vehicle for liquid–gas contact,by multiple drip-points.More resistant to fouling Because a combination of Metal Cascade Mini Rings' vertical alignment and open sides, allow any solids present to be flushed downwards through the packed bed.Good Mechanical Strength which allows Metal Cascade Mini Rings' use in deep packed beds that have a higher hydraulic capacity. Application ﹡Desulphurization and decarburization system in compound ammonia plant ﹡Decompressed plant in crude oil separated plant ﹡All kind of separation process such as separation of methanol ﹡Separation of organic acid ﹡Absorb or disabosorb tower
