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 often presents a major challenge in various industries: coal dust in the atmosphere at loading docks, asphalt dust during concrete production, considerable iron ore dust at mining locations, sugar dust, and comparable substances. Sugar dust is a major challenge for the sugar industry, resulting in substantial revenue losses as the end product becomes sugar...

Ongoing enhancements of current processes and procedures in environmental technology serve as a central focus for both operators and manufacturers. Wet air scrubbers continue to be the primary method for capturing and gathering particulates. Whether a wet or a dry system should be applied is determined by the particular characteristics of the dust in question:...

Asphalt is generally produced from petroleum: oil wells provide petroleum to refineries, where it is divided into different fractions, one being asphalt. It can be altered in numerous ways. Asphalt for paving goes through a mixing process in either a drum mix plant, which is a large-output and continuously operating facility, or a batch plant, which is...

Wet air scrubbers are used to treat 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 technology behind chemical and biological wet air scrubbing at livestock facilities...

Packed tower scrubbers (packed column or packed bed scrubbers) are designed for the chemical scrubbing of contaminants from gas streams. These 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 especially suitable for...

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 the emissions of other sulfur dioxide-emitting processes. SO₂...
