Venturi wet air scrubber is a pollution control device that utilizes the energy of an incoming gas stream in order to atomize scrubbing liquid. The venturi scrubber is made of 3 parts – a converging section, a throat section, and a diverging section. The gas flow enters the scrubber through the first section, where it gains...

Sulfuric acid during zinc production
Zinc mining is a process of metal zinc extraction through mining. Zinc metal is produced using the method of extractive metallurgy which consists of the following steps: the metal ore is first finely ground, then it is put through froth flotation to separate minerals from gangue. The last step results in zinc sulfide ore concentrate...

Removal of nitrogen oxides with wet air scrubbers
Nitrogen oxides are a group of air-polluting compounds. Only one of these compounds – nitrogen dioxide (NO2) – is monitored as an air pollutant, for the creation of acid rain and its reaction with the ozone. Nitric acid, which contains NO2, is used in the production of explosives, flour bleaching, and as an oxidizer in...

Wet air scrubbers in asphalt concrete production
Concrete is an extremely important part of the infrastructure of modern life and its production is a growing sector of industrial production.Asphalt concrete is used in many different applications, most commonly in the construction of highways and roads. A variety of mixtures can be used to manufacture asphalt concrete, some of which include hot mix,...

Wet air scrubber air pollution control
The human impact on the environment has been a topic of discussion for the past 50 years. Climatologists predict that as much as two thirds of all Europeans will have their health impacted by extreme changes in weather by 2100. The extreme weather conditions and events are predicted to cause the death of 150000 people...

Wet air scrubbing remains the most cost effective and versatile
Of all available air pollution control techniques, wet air scrubbing is considered to be the most cost effective and versatile. Most wet air scrubbing techniques are highly effective and provide 99% treatment quality of both particulate matter and aerosol pollutants. Wet air scrubbers are not only effective but also efficient and often require less energy...

Wet air scrubbers for dust control
Wet air scrubbing is often overlooked as a method of air pollution control. The wet air scrubbing technology is not at the forefront of the engineers’ list of equipment for emission control due to the reluctance to change from the well known dry dust collectors. Despite the hesitance, wet air scrubbers are successfully installed downstream...

Wet air scrubber treatment quality
Treatment quality of an air scrubber refers to the general percentage of a pollutant that the scrubber is able to remove. In other words, this measure shows how effective the scrubber performs. The treatment quality of a scrubber is often measured interference to particle and gas pollutants, as some air scrubbers may be far less...

Wet air scrubber for sulfuric acid vapours absorption
Sulfuric acid vapour is one of the main pollutants that occur during zinc production. Sulfuric acid vapours are, in fact, not vapours, but a fine mist or aerosol in a working atmosphere; that can be explained by its low vapour pressure and hygroscopic properties. The mist mainly originates from the electrolyte that consists of a...

Wet air scrubber iron ore dust control
Heavy iron ore dust is a result of iron ore mining. The iron ore contains high quantities of hematite or magnetite, but also other elements that are often present in trace amounts. Such elements include silicon, phosphorus, aluminum, and sulfur. The iron ore itself is not harmful, however, the dust that is produced during transportation...
