Abstract:
A contacting apparatus that increases the efficiency of the transfer of gas to a liquid, comprising:a contactor adapted to receive liquid from a remote source of liquid, the contactor having an upper end and a lower end; a flow splitter dispose between the remote source of liquid and the contactor; a flow adjustment means disposed between the flow splitter and the. upper end of the contactor; a gas injection means disposed between the flow splitter and the lowermost end of the contactor, the gas injection means adapted for fluid communication with a remote source of gas; an upper fluid flow directing moans disposed proximate to the upper end of the contractor at a preselected downward angle so that the liquid follows a downward vortex path of travel within the contractor, a lower fluid flow directing means disposed proximate to the lower end of the contactor at a preselected upward angle so that the gas follows an upward vortex path of travel; an outlet disposed proximate to the lower end of the contactor; and a mixing zone created by the downward vortex flow of liquid and the upward vortex flow of gas.
