A typical lime/limestone Flue Gas Desulfurization (FGD) system consists of three major sub-systems: The reagent (lime or limestone slurry) preparation; The scrubber/SO2 absorber and mist eliminator, and slurry/solid waste disposal systems.

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.

Purge water from a typical wet flue gas desulfurization system contains myriad chemical constituents and heavy metals whose mixture is determined by the fuel source and combustion products as well as the stack gas treatment process.

Duke Energy explains about the capturing of sulfur dioxide using a SO2 scrubber system and how it reduces emissions from the exhaust of coal-fired power plants.

The MECS ® DynaWave ® Reverse Jet Scrubber Technology is the only wet scrubbing technology that accomplishes multiple functions in one vessel and can use a variety of reagents to guarantee low emissions for a wide range of industries.

Our exhaust gas cleaning system, or scrubber, is similar to wet scrubbers. We both use a basic liquid absorbent to react with the acidic gases.

The SO 2 is removed by inducing exhaust gases to react with a chemical absorbent as they pass through a tower.. Limestone Wet Scrubber. This is

SOx compliance mandates use of flue gas desulfurization (FGD). The three methods used in the U.S. to desulfurize flue gas include wet scrubbing (85%), dry scrubbing (12%), and dry sorbant injection (3%).

Power plants often produce wastewaters that contain salts, such as those from wet gas scrubbing, coal pile run-off, and leachate from gypsum stacks. Evaporation of those liquid wastes in a modern zero liquid discharge system produces clean water that is recycled into the plant plus a solid product suitable for landfill disposal.

The primary function of the blast furnace gas cleaning system is to remove particulate matter from this gas. In addition, the system also cools the gas to reduce its moisture content, thus increasing its calorific value.

pH and ORP meters, analyzers and transmitters are used for continuous process monitoring of pH and ORP to ensure water/product quality, monitor effluent discharge, batch neutralization, pulp stock, scrubbers, cooling towers, chemical, water/wastewater treatment and many other applications.

The term "cooling tower" is used to describe both direct (open circuit) and indirect (closed circuit) heat rejection equipment. Cooling towers are heat-transfer units, used to remove heat from any water-cooled system.
