The whole truth about gas scrubbing

The process of scrubbing is complicated and needs the use of special nozzles that help to take away pollutants and other chemical contaminants from process gases, liquids, and equipment. For example, coal fired power plants use scrubbers with the aim of removing sulphur oxides from boiler exhaust, also it is possible to take away nitrous...

Wet air scrubbers are the only solution for the shipping industry

Everyday climate of the Earth continues to change as a result of greenhouse effect and human activity or, to be more precise, different emissions from such activities. At the present time the shipping industry is one of the largest sources of sulfur oxides pollutions, behind the energy industry all around the world. Moreover, about 70...

Ecological Engineering: Wet Air Scrubbers

All companies that produce, use or handle more than the threshold quantities with at least one of these substances will be obliged to have an approved release prevention and control program. These limits will be based on toxicity, flammability and amount of the substances which have serious destructive effects on human health. Remediation measures will...

Underground Coal Dust Scrubbers in Coal Mining

For power plants handling millions of tons of coal a year, minimizing coal dust as a high 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...

Wet Air Scrubbers as Highly Efficient Sugar Dust Collectors

Dust is often a major problem in a lot of different industries: coal dust from the air at loading facilities, asphalt dust during concrete production, heavy iron ore dust at iron mines, sugar dust, and suchlike. Sugar dust is a major nuisance for the sugar industry as it causes a substantial loss in revenue due...

High Performance of Venturi Scrubbers in the Removal of Particulates

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...

Wet Air Scrubber vs. Greenhouse Effect

The greenhouse effect is a regular process that warms the Earth’s surface. The Sun’s energy reaches the Earth’s atmosphere, then some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The greenhouse effect problem is that human activities (burning of fossil fuels, agriculture, and land clearing) are...

Air Quality Control in Asphalt Manufacturing Process

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 Scrubber Techniques for Emission Reduction at Livestock Farming

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 Wet Air Scrubbers Overview

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...
