Annular flow pressure drop model for pease–anthony‐type venturi scrubbers

Abstract

Abstract An annular flow pressure drop model has been developed and compared with experimental data obtained on a pilot‐plant‐size Pease‐Anthony‐type venturi scrubber. Droplet and film accelerations as well as wall friction, based on the two‐phase Lockhart‐Martinelli correlation, are considered. Excellent agreement with experimental data is demonstrated for a wide range of throat gas velocities, liquid to gas ratios, and film flow rates for a single scrubber geometry.
