| Wet Scrubbers: Wet scrubbers comprise a | | | | gasoline engines. |
| combination of various devices that remove | | | | Catalytic Converter: A catalytic converter is an |
| pollutants from furnace flue gas as well as other | | | | equipment used to reduce the toxicity of |
| gas streams. They are used in different kinds of | | | | emissions produced by internal combustion |
| industries like large power plants, asphalt plants, | | | | engines. Catalytic converters are typically used in |
| steel plants, fertilizer plants etc. | | | | the exhaust systems of motor vehicles and in |
