State of the Art in Air Pollution Control for Sinter Plants
In the last 25 years, a second-stage off-gas cleaning system was installed at several sinter plants to comply with lower emission limits for dust, SO 2 and PCDD/F. This additional cleaning stage can be a wet system or a dry system (Menad et al. 2006; Delwig et al. 2007; Guerriero et al. 2009).However, dry systems using a sorption process are …

Consider Wet Scrubbers for Pollution Control
Scrubbers fall into two generalized categories, wet and dry. This article focuses on wet scrubbers, how they operate, and advantages and disadvantages of each type. Wet scrubbers use a liquid to remove pollutants from a contaminated gas stream via absorption. In most cases, the liquid is water, as it is readily available at most facilities.
