Calculate the throat area of a Venturi scrubber to operate at specified collection efficiency(USEPA-84/09, p. 77).
Given:
Volumetric flow rate of process gas stream = 11,040 acfm (at 68°F)
Density of dust = 187 lb/ft3
Liquid-to-gas ratio = 2 gal/1000 ft3
Average particle size = 3.2 μm (1.05 × 10–5 ft)
Water droplet size = 48 μm (1.575 × 10–4 ft)
Scrubber coefficient k = 0.14
