Abstract: A tower structure for gas-liquid interaction produces rolling turbulence in a gas flow path that has low pressure drop. The structure includes a spaced plurality of vertically disposed wall members in an upwardly directed flow path, a staggered array of horizontally extending deflectors protruding from facing wall members, forming a series of converging and diverging chamber portions in which the gas flows generally perpendicular to the deflectors. Rolling turbulence is produced between apexes of the deflectors and the facing wall portions, the gas flow being offset toward opposite wall members at succeeding apexes. In one configuration, a liquid is transported within the gas flow, in contact with the gas. In another configuration, the liquid is separate from the gas. In a further configuration, two liquid paths are provided, one in contact with the gas, one separate from the gas.
