Abstract
A liquid-vapor contact device having a plate-like body provided with a central section formed of expanded metal construction. The expanded metal construction provides slit-like openings for the vapor to ascend through the plate-like body and mix with liquid traversing the plate-like body. Tongue-like flow deflectors associated with the openings impart momentum to the vapor in a flow direction taken from inlet and outlet segments of the plate-like body. A plurality of elongated members overlie the central segment of the plate-like body. The plurality of the elongated members define channels running from the inlet and outlet segments which are preferably outwardly curved to ensure complete liquid distribution across the plate-like body. In addition, flow impedance members in the form of cut and bent tabs impede the flow of liquid across the plate-like body while flinging liquid against side surfaces of the elongated members to produce a falling film and therefore a secondary mechanism for liquid-vapor contact.
