Spray Dryer Absorber GEA engineering for a better world

The Spray Drying Absorption process is a versatile way of cleaning flue gases by the removal of acid gases and particulates generated by fossil-fuel burning, mainly coal. Because of the presence of large volumes of flue gasses, power plant installations frequently have more than one Spray Dryer Absorber

Circulating Fluidized Bed Scrubber vs. Spray Dryer Absorber

Sep 14, 2015· The first technology is the spray dryer absorber (SDA), which sprays atomized lime slurry droplets into the flue gas. Acid gases are absorbed by the atomized slurry droplets while simultaneously

Impact of solid waste treatment from spray dryer absorber

Oct 15, 2017· The semi-dry technology has typically been employed on small to moderate size plants. Because of size limitations on the absorber tower, the maximum power served by a spray dryer is about 250–350 MW. Power plants with semi-dry FGD usually burns low-sulfur coal, in virtue of a limit of 95% on SO 2 removal efficiency. The semi-dry technology is

Spray Dry Scrubber an overview ScienceDirect Topics

Bruce G. Miller, in Clean Coal Engineering Technology (Second Edition), 2017. Spray dry scrubbers. Spray dry scrubbers are the second most widely used method to control SO 2 emissions in utility coal-fired power plants. Prior to 1980, the removal of SO 2 by absorption was usually performed using wet scrubbers. Wet scrubbing requires considerable equipment, and alternatives to wet scrubbing

The economic solution for Flue Gas Desulphurisation

The rotary atomizer and spray dryer absorber Central to GEA Niro’s SDA process is the concept of using a spray dryer as both an absorber and dryer simultaneously. Achieving this hinges on two crucial pieces of equipment the GEA Niro rotary atomizer and gas disperser. The former atomises feed slurry into billions of droplets, while the latter

Power Plant Saves Over US$20,000 Annually on Tank

Power Plant Saves Over US$20,000 Annually on Tank Cleaning Labor Problem: A Midwestern coal-fired power plant injected a lime reagent into a Spray Dryer Absorber (SDA) to control the emission of sulfur dioxide. The power plant recovered unspent lime from fly ash created during the combustion process. The fly ash was mixed with fresh lime to

Scrubber Wikipedia

Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictineo I, a role for which they continue to be used today.

Zero Liquid Discharge Compliance Strategies for FGD

A wastewater spray dryer ZLD approach transfers FGD blowdown to a spray dryer vessel in which hot flue gas, prior to the air preheater, is diverted from the main flue gas path to evaporate the liquid. The FGD blowdown is taken from the overflow of the secondary hydroclone, no longer requiring the use of the existing physical/chemical WWT facility.
