3. Important applications of a suitable, optimized packing material for wet scrubbing
Solution
1. Evaluation of packing materials for scrubbing removal of sulfur dioxide is presented
in Table 19 and Fig. 13. The data in Table 19 and Fig. 13 show that Q-PAC is slightly
more efficient than 2K Tellerettes at less than half the pressure drop per foot.
Compared with 3.5 in. Tri-Packs (see Table 18 and Fig. 12), Q-PAC is approximately
40% more efficient with about half the pressure drop.
