The scrubbing process is intricate and requires special nozzles designed to remove pollutants and various chemical contaminants from gases, liquids, and equipment involved in the process. For instance, coal-fired power stations utilize scrubbers to eliminate sulfur oxides from boiler emissions. Additionally, it is feasible to extract nitrogen oxides from combustion emissions, acids from chemical processing...

The daily climate of the Earth keeps changing due to the greenhouse effect and human actions, or more specifically, various emissions resulting from these activities. The shipping industry ranks among the top contributors to sulfur oxide pollution, second only to the energy sector. Additionally, approximately 70% of shipping emissions occur within 250 miles of the...

Every business that manufactures, utilizes, or manages quantities exceeding the threshold limit of any of these substances must implement an authorized release prevention and control plan. These limits will be based on toxicity, flammability, and amount of the substances that have serious destructive effect on human health. Most manufacturers and users of these pollutants will...

For power plants processing millions of tons of coal annually, reducing coal dust is a top priority. A wide range of technologies is used to manage, control, and prevent coal dust in and around coal-fired power plants. Coal-fired plants are turning to high-tech dust suppression systems to control fine airborne coal particles known as fugitive...

Dust frequently poses a significant issue across numerous industries: coal dust in the air at loading docks, asphalt dust while producing concrete, substantial iron ore dust at mining sites, sugar dust, and similar types. Sugar dust poses a significant problem for the sugar industry, leading to considerable revenue losses because of the final product being...

Further developments of existing processes and procedures in environmental technology form a focal point for operators and manufacturers. Wet air scrubbers remain the main force for the capture and collection of particulates. Whether a wet-working or a dry system should be applied is determined by the particular characteristics of the dust in question: small dust...

Nowadays asphalt is typically processed from petroleum: oil wells supply petroleum to oil refineries, where it is separated into various factions, one of which is asphalt. Them asphalt may be modified in a variety of ways. Asphalt for paving goes through a mixing process in either a drum mix plant, where is a large-output and...

Wet air scrubbers are used on ventilation air as it exits livestock housing. Some wet scrubbers use water, which is then partially recirculated, while others use an acid or base to shift the pH for absorption of specific gases in the air. The current technology behind chemical and biological wet air scrubbing at livestock facilities...

Packed tower scrubbers (packed column or packed bed scrubbers) are designed for chemical scrubbing of contaminants from gas streams. Such scrubbers are versatile, reliable systems that serve the widest variety of processes. Packed tower scrubbers are highly recommended for the efficient removal of inorganic gases, odors, and fumes. These scrubber systems are particularly appropriate where...

Over the past several decades there have been immense improvements in process chemistry, a better understanding of materials, simplified designs, and other technological enhancements. Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO₂) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur dioxide emitting...
