There are several different types:
Wet: Typically scrubbers are big round vertical tanks. The polluted gas stream flows upward through a media (think packing peanuts, but heavy plastic) as a downward flow of water washes the gas stream. This is a very typical and fairly effective way to remove pollutants. Facilities can achieve 95% removal efficencies IF the are monitoring their scrubbing conditions, such as pH and adding any reagents necessary for optimization.
Dry: Bag houses are a bunch of giant vacumn cleaner looking bags to physically filter the air. A shaker system shakes the bags, or changes the airflow to clean them and excess filtered particulate can then be collected and removed, reducing service intervals. Removes most particulates but ultrafines are sometime missed and the condition and maintanance of the bags and the shakers has everything to do with it.
Electronic: An ionic breeze on steroids, these electrostatically remove particulates from exhaust gasses. Old technology and typically found at old coal fired powered plants.
All these above will remove filterable or condensible contaminants but will do little to quell NOx emissions. The new fancy way is this:
Catalytic: Just like your car, or more like a modern diesel engine, a smoke stack can be fitted with a catalyst bed to help scrub NOx (oxides of nitrogen ie NO, No2, n20) with the addition of an ammonia source such as anhydrous ammonia or urea. This catalytic action must take place closer to the combustion than other methods, and typically run about 800*F. The ammonia reacts with the NO2 and with the assistance of a catalyst, reduces it down to N2 and 02. Continuous monitoring of ammonia injection, NOx and montitoring of "ammonia slip" out the other side of the system (too much ammonia and it wont all get used up...just the right amount and theres none left)
Thermal. Do little to change the levels of C02, o2 and NO2 as the exhaust gasses will be typical of natural gas combustion. The gas to be cleaned is passed through an incinerator to burn off anything left from an industrial process. These things save lives!
Been testing these things using ASTM, EPA, and various approved methods for years.
What else can I help you with?
What apparatus is often used to remove poisonous gases from industrial emissions before they are released into the atmosphere?
A common apparatus used for this purpose is a scrubber system. Scrubbers remove pollutants from industrial emissions by passing them through a liquid or solid material that captures the harmful gases. This helps to reduce the environmental impact of releasing toxic substances into the atmosphere.
What device is used to remove poisonous gases from industrial emissions before they are released into the atmosphere?
The device used to remove poisonous gases from industrial emissions is called a scrubber. Scrubbers work by spraying a liquid solution that captures harmful pollutants, such as sulfur dioxide and particulates, from the gas stream. The cleaned gas is then released into the atmosphere, significantly reducing environmental impact. There are various types of scrubbers, including wet and dry scrubbers, each suited for specific applications.
What it used to remove poisonous gases from industrial emissions before they are released into the atmosphere?
A common method used to remove poisonous gases from industrial emissions is through the use of scrubbers or absorbers. These devices involve passing the emissions through a solution that can absorb or react with the harmful gases, removing them before the emissions are released into the atmosphere. This process helps to reduce air pollution and minimize the impact of harmful gases on the environment and human health.
What is used in smokestacks to reduce air pollution?
There are several systems which can be used in stacks to reduce pollutions:ScrubberElectrostatic precipitatorsBag housesCyclonesCatalytic chambersImpingement platesHeat recovery systemsChemical addition
What is emissions equipment?
Emissions equipment refers to technologies and devices designed to reduce or control the release of pollutants and greenhouse gases from industrial processes, vehicles, and power plants. This includes components like catalytic converters, scrubbers, and filters that capture harmful substances before they enter the atmosphere. The goal of emissions equipment is to comply with environmental regulations, improve air quality, and minimize the impact of human activity on climate change.
Does calcium carbonate remove harmful emissions?
Calcium carbonate can be used in some industrial processes, like flue gas desulfurization, to help remove harmful emissions such as sulfur dioxide. It reacts with the emissions to form less harmful compounds like calcium sulfite or sulfate, which can then be safely disposed of.
What does scrubber mean?
A scrubber is a device used to remove pollutants or impurities from gases, liquids, or surfaces. In the context of air pollution control, scrubbers are commonly used to remove harmful chemicals and particles from industrial emissions before they are released into the atmosphere.
Since 1977 scrubbers have been required for the exhault fumes of all new fossil fuel burning power plants and smelters These devices are used to reduce emissions of?
sulfur dioxide and other pollutants by trapping them before they are released into the air. Scrubbers work by using a wet process to scrub the emissions and remove harmful particles and gases, helping to improve air quality and reduce environmental impact.
Most sulfur oxides are produced by burning?
Most sulfur oxides are produced by burning fossil fuels such as coal and oil. These oxides can have harmful effects on human health and the environment, contributing to acid rain, smog, and respiratory issues. Implementing technology such as scrubbers can help reduce sulfur oxide emissions from industrial processes.
What is a system that removes certain gases and particles from industrial exhaust?
A system that removes certain gases and particles from industrial exhaust is known as a scrubber. Scrubbers use various methods, such as chemical reactions, to capture and neutralize harmful pollutants, including sulfur dioxide and particulate matter. They can be wet or dry, with wet scrubbers using liquid solutions to absorb gases and dry scrubbers employing solid materials. This technology helps to reduce air pollution and meet environmental regulations.
What is called the smoke that comes out of a factory?
The smoke that comes out of a factory is typically referred to as industrial emissions or industrial smoke. This smoke is a byproduct of various industrial processes and often contains pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides. These emissions can have harmful effects on the environment and human health if not properly controlled and regulated.
What is an factory smokestack?
A factory smokestack, also known as a chimney, is a tall structure designed to vent exhaust gases and smoke from industrial processes into the atmosphere. It helps to disperse pollutants over a larger area, reducing ground-level concentrations of harmful emissions. Smokestacks are typically found in power plants, manufacturing facilities, and other industrial sites. Their height and design are crucial for minimizing environmental impact and adhering to air quality regulations.
