Because of holding high specific level, structured packing enhanced tower efficiency and through their structure make the pressure drop throughout the tower. A new design has been presented in order to increase the special level of these packing, which in addition to HETP they will reduce gas pressure too. Also through changing the kind of holes in special kind of structured packing it has been tried to improve gas distribution in tower which led to good results. Regarding no mass transferring in special places of tower it has been tried to remove this deficiency. In some points of tower which the liquid gathers and has redistribution there exist very little contact between the 2 phase and actually the amount of mass transferring will be deemed as nothing. It has been tried to innovate a novel kind of gathering device through the representation of a design for gathering device which in addition to having less height than other gathering device will have comparable specific level with packing which in the past there has not been any action in this regard. This packing when gathering liquid in the center of tower will increase the contact level of the two phases and through this process it will reduce the final height of tower.
