Numerous undesirable products are produced in the result of fuel combustion processes. Thus, flue gases include carbon monoxide, carbon dioxide, sulfur oxides, nitrogen oxides, acids and aerosolized metal oxides that cause poor air quality, and consequently, air pollution. Nonetheless, the majority of electric carbon monoxide, carbon dioxide, sulfur oxides, nitrogen oxides, acids, and aerosolized metal oxides use various air treatment devices, the most popular of which are scrubbing systems.
Scrubbing systems are considered to be air treatment technology for combustion applications, to be precise, coal and oil electric power generation. It should be noted that the first Clean Air Act was amended in 1970. It allows regulating emissions of dangerous air pollutants, as well as establishing emission standards that require the reduction of toxic air pollutants from power plants.
Scrubbers are the best air treatment device for flue gas processes. Scrubbing systems are suitable for both liquid- and solid-type gas treatment processes that depend on the physical and chemical properties of the removed contaminant. Also, there are two types of scrubbing systems that include dry scrubbers and wet scrubbers, adsorbents and mercury removal processes resulting in solid water-soluble salts that can be then collected.
All the air treatment devices for flue gas processes have to withstand harsh conditions, especially, the high temperature that may vary from 982°C to 1316°C (1800°F to 2400°F). During the operation, scrubbing systems produce white vapors that are mostly water vapor generated and do not include any hazardous particulate matter or carbon byproducts.
For example, carbon dioxide scrubbers enable to turn CO2 to solid carbonates and this air treatment device can be applied even at space stations and submarines to take away CO2 from exhaled gas and prevent excess accumulation in the air. Nevertheless, the most popular scrubber application is the removal of sulfur from flue gas.
Dry scrubbing systems apply alkaline media, for example, hydrated lime or soda ash (sodium carbonate) for the air treatment. However, dry scrubbers are considered to be not as efficient or as effective as wet scrubbers, maybe because of less favorable contact conditions in the hot, rapidly moving flue gas. Therefore, dry scrubber application is limited by the use in smaller-scale hospital and municipal incinerators due to their convenience.
Wet air scrubbers apply an alkaline solution, for example, a slurry of limestone (calcium carbonate), lime (calcium oxide/calcium hydroxide) or sea water. Also, wet scrubbers are highly efficient for removal of water-soluble mercury species, to be precise, more than 90% mercury is possible to remove.
Optromix is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber is able to remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.
