Acid Gas/SO2 Controls - Institute of Clean Air Companies
Wet scrubbers are used in industrial process mercury removal and to remove ionic forms of mercury from the gas stream of coal-fired power generation facilities. Wet scrubbers generally have relatively small space requirements, low capital cost, and are able to process high temperature, high acidity, and high humidity flue gas streams.
5.8.4 Scrubber Sludge Systems. Boiler systems that contain wet flue gas desulfurization systems (shown in Fig. 5.1 and discussed in detail in Chapter 9) must handle the solid effluent from the scrubber (also called the scrubber sludge), which contains the reaction products from limestone and SO 2.

Our dry sorbent injection (DSI) systems provide a low-cost solution to capture acid gases, either separately or combined, in coal-fired boilers (typically less than 300 MW), biomass boilers and industrial applications. On larger units, DSI systems also can be used for HCI or SO 3 control when combined with other air emissions control technologies.

A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

CHAPTER 41 WET GAS SCRUBBING Wet scrubbers use a liquid to remove solid, liquid, or gaseous contaminants from a gas stream. The scrubbing liquid performs this separation by dissolving, trap-ping, or chemically reacting with the contaminant. Scrubbers are used extensively to control air polluting emissions. So many dif-
What Is A Wet Scrubber? - CECO Environmental Corp.
In contrast to dry scrubbers, wet scrubbers move contaminated gas through a liquid that is designed to remove pollutants. Wet scrubbers constitute a versatile and cost-effective pollution control technology that can eliminate more than 99% of airborne particulate matter. How Wet Scrubbers Work

The gas leaves the scrubber at its dew point, so even though significant amounts of water may have been removed from the cooled gas, it is likely to leave a visible stack plume of water vapor. Dry scrubbing. A dry or semi-dry scrubbing system, unlike the wet scrubber, does not saturate the flue gas stream that is being treated with moisture. In
2. Scrubber systems Wet scrubber systems are used to remove the SOx from exhaust gas. The process involves funnelling the exhaust gas through the scrubber tower, where it is sprayed with water. In most cases, the scrubber produces back pressure. The picture below shows an Alfa Laval PureSOx scrubber, which has a U-type design.
