Abstract

Empirical models were developed to describe the fluid flow characteristics and gas absorption efficiency of an ejector venturi scrubber. The empirical constants were determined experimentally using stop action photographs of the spray, static pressure measurements, and sulfur dioxide absorption efficiencies. Experiments were conducted on a commercial scrubber, 24 inches (61 cm) high, with a 4 inch (10 cm) diameter gas inlet and outlet. Liquid flow rates varied from 3 to 8 gallons/min (.0114 to .0303 m3/min) in the atomizing range of the scrubber, and gas flows from 24 to 64 cubic feet/min (.680 to 1.81 m3/min). The liquid‐to‐gas ratio was constant at .0167. Droplet sizes ranged from 34 to 563 microns, with a volume mean diameter of 155 microns, at a liquid rate of 6 gpm (.0227 m3/min). The sulfur dioxide mass transfer coefficient varied from 25 to 800 lb‐mole/hr‐ft3 (400 to 12,800 kg‐mole/hr‐m3). Copyright © 1987 American Institute of Chemical Engineers
