Air pollution control engineering

The phenomenon of air pollution includes a sequence of events: the generation of pollutants at and their release from a source; their transport and transformation in and removal from the atmosphere; and their effects on human beings, materials, and ecosystems. Generally, either economically infeasible or technically impossible to design processes for absolutely zero emissions of...


Wet Scrubber Limitations

Wet scrubbers clean air by physically trapping PM on wet surfaces and absorbing gasses into the liquid. In some cases, the gasses react with chemicals in the liquid, too. Small liquid droplets are more effective per unit volume of scrubber liquid because they have more surface area than fewer, larger droplets. Very small liquid droplets,...
