Scrubbing and flue gas treatment for . - Igniss Energy

Dry and wet scrubbing. Scrubbing is flue gas treatment of poluted flue gases by chemical reaction, like gasses from incineration processes are chemically treated before leaving the chimney. When water (and for example caustic soda - NaOH) is used to clean the flue gas, it is called "wet scrubbing".

Some vapors or fumes that aren't water-soluble could be good targets for a dry scrubber or dry sorbent injection (DSI) system. The most common type of dry scrubber is a limestone-based scrubber which uses limestone powder. Most gas scrubber applications are best suited to use a liquid-based scrubber. Applications include gases such as:

Wet Flue Gas Desulfurization with Lime/Limestone Slurry

In wet flue gas desulphurisation, open spray tower absorbers have prevailed which are divided into two principal zones. These are the absorption zone exposed to the flue gas and the absorber sump, in which the limestone slurry is trapped and collected. To prevent deposits in the absorber sump, the slurry is suspended by means of mixing mechanisms.

Various scrubbing processes have been proposed to remove CO 2 from the air, or from flue gases. These usually involve using a variant of the Kraft process. Scrubbing processes may be based on sodium hydroxide. The CO 2 is absorbed into solution, transferred to lime via a process called causticization and released in a kiln.
