Grain dust explosion solutions

The presence of grain dust in the air poses a significant threat as it can cause damage to equipment, reduce its work time, and injuries to workers. Controlling grain dust is a crucial process and a challenge. The grain dust present in the air can result in an explosion as it is highly combustible; large...

Acid gas control methods

Acid gases from power plant and boiler combustion, such as sulfur dioxide and hydrogen sulfide, pose a major threat to human health and the environment. The main ways that acid gases deposit themselves is through acid rains and dry deposition. The consequences of acid rains are devastating: the presence of dead or dying plant life...

Ejector venturi wet air scrubber

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 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...
