There are several types of exhaust gas scrubbers including:
Wet scrubbers: This type of scrubber uses water to remove pollutants from the exhaust gases. The contaminated water is then treated and the pollutants are removed before being released into the environment.
Dry scrubbers: Dry scrubbers use chemicals to remove pollutants from the exhaust gases. The chemicals react with the pollutants to form solid particles that can be easily filtered out of the exhaust gases.
Hybrid scrubbers: Hybrid scrubbers are a combination of wet and dry scrubbers, and they use a combination of water and chemicals to remove pollutants from the exhaust gases.
