Capital cost for Impingement Plate Scrubbers

Impingement plate scrubber costs are dependent on the number
of plates and the total gas flowrate. The costs for impingement scrubbers are based on data that
corresponds to a total gas flowrate between 900 and 77,000 ACFM or above. For total gas flowrates
above 77,000 ACFM, multiple scrubbers are required. Figure 1 presents cost curves for
impingement plate scrubbers with total gas flowrates between 900 and 77,000 ACFM. Cost curves
for scrubbers with total flowrates above 77,000 ACFM are shown in Figure 2 and require the
use of 2, 3, or 4 identical scrubber units. All the cost correlations shown here are for sieve plate
scrubbers with three plates. Impingement plate scrubbers are usually constructed with carbon steel.
Some applications may require more expensive materials, such as coated carbon steel, FRP, or
polyvinyl chloride (PVC)
