Smaller Tower Diameters Using Q-PAC Tower Packing
Example: 50,000 cfm odor control scrubber (H2S control) at a typical municipal waste water treatment plant.
Tower diameters required using different scrubber packings:
| Packing Type | Design Gas Velocity | Tower Cross Sectional Area | Tower Diameter |
| 1.5" Saddles, 2" Pall Rings | 290 ft/min | 50,000/290 = 172 ft2 | 15 ft |
| 3.5" Tri-Packs | 442 ft/min | 50,000/442 = 113 ft2 | 12 ft |
| Lantec Q-PAC | 637 ft/min | 50,000/637 = 78.5 ft2 | 10 ft - best choice |
10-ft Tower Advantages
>> Lower material costs
>> Lower fabrication costs
>> No need for special highway permitting/routing/escorting
>> No field erection expenses
