A gas washer. See under Gas.
a device for removing pollutants from a gas stream, especially for removing sulfur oxides from processes burning coal or oil.
A device for removing unwanted gases or particles from an air stream by spraying the air with liquid (usually water) or forcing air through a series of baths. Scrubbers are often put on smoke stacks.
A pollution control device in the stack of a coal-burning facility which uses a liquid spray to remove pollutants, especially sulfur dioxide, from emissions. The process is called flue gas desulfurization.
An emission control device that adds alkaline reagents to react with and neutralize acid gases.
An air pollution device that uses a spray of water or reactant or a dry process to trap pollutants in emissions.
Any device in which a contaminant, solid or gaseous, is removed from a gas stream by impacting it with liquid droplets. (Types include spray towers, packed towers, cyclone scrubbers, jet scrubbers, venturi scrubbers and impingement scrubbers.)
A filter that removes particles and contaminants from the air. Primitive scrubbers to remove CO2 from a vessel's air supply have been in existence since the days of ancient submarine warfare. Modern scrubbers use biological agents to turn CO2 into oxygen and defensive nanobots to repel enemy nanobot attacks (see Technology, Nanotechnology).
a device that uses a high energy liquid spray to remove aerosol and gaseous pollutants from an air stream. The gases are removed either by absorption or chemical reaction
A device used to treat dust and gas fumes. Dry scrubbers use adsorbents to eliminate certain contaminants, while wet scrubbers treat dust and gas fumes through contact with a liquid.
Any of several forms of chemical/physical devices which operate to neutralize sulfur compounds formed during coal combustion. These devices combine the sulfur in gaseous emissions with other chemicals to form inert compounds, such as gypsum, that must then be removed for disposal. Although effective in substantially reducing sulfur from combustion gases, scrubbers require about 6% to 7% of a power plant's electrical output and thousands of gallons of water to operate.
a purifier that removes impurities from a gas
a chemical factory that you build next to a power plant that takes the sulfur out of the stacks
a fairly simple device, which is able to treat large volumes of air
a wet air cleaning technique/equipment for the removal of water soluble contaminants (eg
Any of several forms of chemical/physical devices that remove sulfur compounds formed during coal combustion. These devices, technically know as flue gas desulfurisation systems, combine the sulfur in gaseous emissions with another chemical medium to form inert "sludge," which must then be removed for disposal.
An apparatus for purifying gases.
an antipollution device that uses a spray to remove pollutants from a stream of air passing through a smokestack.
emission control device in an incinerator, used primarily to control acid gases, but also to remove some heavy metals.
is a device in which dust or gaseous impurities are removed using droplets of water.
is a device in which rock is washed to remove fine particles of rock or clay from the surface of larger particles.
A device used to removal particulates or pollutant gases from combustion or chemical process exhaust streams.
a pollution control device that sprays a stream of water across or through a stream of polluted air to remove pollutants. Scrubbers are widely used in a variety of combustion processes.
Common antipollution device that uses a liquid or slurry spray to remove acidic gases and particles from municipal waste combustion facility flue gas.
device for removing contaminants from an air stream by "washing" air with water or some other neutralizing agent.
A unit which removes undesired substances from a gas by dissolving them in a liquid "scrubbing" agent.
An apparatus for the removal of solids from gases by entrainment in water.
