• Wet scrubbers remove particles by capturing them in liquid droplets.

• Wet scrubbers remove pollutant gases by dissolving or absorbing them into the liquid.

• Wet scrubbers that remove gaseous pollutants are referred to as absorbers.

• the packed tower and the plate tower

• Dry scrubbers use spray dryer absorption and dry injection adsorption.
