For example, Martin Drake Power Plant in Colorado (pictured) is trying out a new stack
gas scrubber design, with water as a pollutant capturing medium.
Here you can crank a handle to generate electricity to electrolyse water into hydrogen and oxygen (and recombine them with a bang), operate a miniature chemical plant or
a gas scrubber, measure the pH of various common substances, or discover your personal hot spots by lying against a large sheet of liquid crystals.
The kiln is fitted with a condenser to capture oils in the exhaust and
a gas scrubber to clean up its gas emissions.
One way CA refineries can meet their targets is to clean up their processes by installing equipment like flue
gas scrubbers.

Limestone
scrubbers deployed at natural
gas power plants could help reduce carbon emissions as well as lower ocean acidification by pumping a byproduct of the scrubbing process back into the water, according to an experiment conducted by the Energy Department's Lawrence Livermore National Laboratory.
Another $ 3.5 - billion plant planned for Sweetwater, Tex., would burn pulverized coal to generate 600 MW of electricity while capturing its 5.75 million metric tons of emissions postcombustion with amine or ammonia
scrubbers or, possibly, with advanced membranes that separate CO2 from other flue
gases.
The second uses various forms of chemistry — in the form of amine or ammonia
scrubbers, special membranes or ionic liquids — to pull carbon dioxide out of a more mixed set of exhaust
gases.
Air pollution control devices called
scrubbers use a sprayed slurry of ground limestone and water to remove sulfur dioxide from
gases formed in coal combustion, said Tom Schmaltz, environmental director for Headwaters Resources, a world leader in coal combustion products.
Over about 8 months, the researchers found that the biotrickling filter was as efficient as a chemical
scrubber, requiring only about 1.5 seconds of contact to remove the
gas.
The use of
scrubbers (yes China and India installed
scrubbers although not used consistently) to remove SO2 along with the shift to natural
gas means the amount of aerosols has not kept up with CO2 forcing.
If we want to reduce CO2 emissions, make the coal,
gas, and oil fired powerplants install CO2
scrubbers / processors and give tax incentives and lawsuit immunity to private investment for Nuke Plants.
Carbon separation is an integral part of syngas processing for F - T (the H / C ratio has to be adjusted, and contaminant acid
gases like H2S removed; amine
scrubbers get CO2 along with the H2S).

scrubber that will remove CO2 from smokestack
gas.
Some older coal - fired generators were retrofitted with various environmental controls (see chart for data on installations of one type of control, the flue

Wet
scrubbers are used to capture both particulates and SO2 by injecting water droplets into the flue
gas to form a wet by - product.
China has deployed the world's largest fleet of sulfur dioxide (SO (2)-RRB-
scrubbers (flue
gas desulfurization systems), and most of them now appear to be operating properly.
FGD
scrubbers have higher capital costs but lower operating costs than DSI systems, along with a higher removal rate for SO2 and other acid
gases (90 % of SO2 emissions for FGD, compared to 70 % for DSI).
SOx is very water soluble: indeed, «
scrubbers» wash SOx from flue
gases by passing the
gases through a water shower.
Costs of German and UK electricity would increase if their coal - fired power stations had to remove SOx from flue
gases by use of «
scrubbers» (i.e. flue
gas desulphurisation; FGD).
A plant may retire if higher coal prices, lower wholesale electricity prices (often tied to natural
gas prices), or reduced utilization make investment in equipment like
scrubbers uneconomical.
To meet this goal, plant owners can implement one of or a combination of three main strategies: use lower sulfur coal in their boilers, retire plants without emissions controls, or install emissions control equipment — primarily flue
gas desulfurization (FGD)
scrubbers.
FGD
scrubbers remove the SO2 from a boiler's post-combustion exhaust (flue
gas) by passing it through an alkaline solution.
She says that solutions include greater use of
scrubbers, increased energy efficiency, and switching from coal to natural
gas, nuclear power, and renewables.
Studies have suggested serious insufficiencies in the safety measures at the installation, including lack of safety valves to prevent the mixing of water into the Methyl isocyanate tanks which started the evolution of the toxic
gas, and the failure of
scrubbers to treat the
gas leak — apparently they were out of service for repair.
With
scrubbers in place, less dust, vapor, and
gases will go through the baghouse filter and up the stacks; but they will create sulfurous acids, suspended fines, and a precipitate in the
scrubber water.
Scrubbers reduce soot emissions and most
gases from burning fossil fuels, especially coal?
On December 1, 2009, Progress Energy announced that by 2017 it will be shutting down all of its coal - fired power plants that do not have flue -
gas desulfurization controls (
scrubbers).
