It draws the benefits of Rasching ring and its height-diameter ratio is 1:2.By increasing cone flanging, it can reduce the resistance of gas and increase the intensity of packing, also increase gas-liquid contact area.

Application: desulfurization of amine, synthesis of amine decarbonization, common decompression such as methanol separation, separation of organic acids and so on.
