Environmental Protection | Chemical Processing Expert Forum

Solids accumulate because of evaporative processes, and in order to control the solids buildup, one has to waste high solids water and replace it with lower solids water. That is blowdown. The same thing is true in a scrubber, only the solids buildup tend to be particulate if it is operating on flue gasses, and salts if it is operating on a

ExhaustGas Scrubber WashwaterEffluent

In a wet scrubber, the exhaust gas is mixed with washwater, and the water-soluble components of the exhaust gas are removed by dissolution into the washwater. SOx scrubbers are capable of removing up to 95 percent of SOx from ship exhaust (EGCSA, 2010). By removing sulfur from the exhaust, the scrubber also removes most of the direct sulfate

Venturi Scrubber for Particulate Removal - Envitech, Inc.

Envitech's Venturi scrubber takes advantage of water vapor condensation to enhance sub-micron particulate collection. In the condenser/absorber, water vapor is condensed from the process gas stream. Some of the water vapor condenses on the particles causing their mass to increase and making them easier to collect in the Venturi section.

Scrubber - Wikipedia

In this mode, termed a condensing scrubber, water from the scrubber drain is circulated through a cooler to the nozzles at the top of the scrubber. The hot gas enters the scrubber at the bottom. If the gas temperature is above the water dew point, it is initially cooled by evaporation of water drops.

Sulfur Dioxide Scrubbers - Air Quality - Duke Energy

An SO 2 scrubber system is the informal name for flue gas desulfurization (FGD) technology, which removes, or "scrubs," SO 2 emissions from the exhaust of coal-fired power plants. A scrubber works by spraying a wet slurry of limestone into a large chamber where the calcium in the limestone reacts with the SO 2 in the flue gas.

Scrubbers - Global Energy Monitor

Rather than trying to remove sulfur from coal before it was burned by washing it, which had little effect, scrubbers aimed at the “back end” of a power plant, trying to remove sulfur in the form of sulfur dioxide (or SO2) from the flue gas exiting a coal boiler.

Wet scrubber - Wikipedia

The term wet scrubber describes a variety of devices that remove pollutants from a furnace flue gas or from other gas streams. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants.

Coal plants without scrubbers account for a majority of U.S

SO 2 is formed during the combustion of coal. The amount of SO 2 produced depends on the sulfur content of the coal burned in a boiler. FGD scrubbers remove the SO 2 from a boiler's post-combustion exhaust (flue gas) by passing it through an alkaline solution. This process is also effective in removing acid gases, such as hydrochloric acid.
