time. Separation of pollutants carried out using a liquid that
will be binding and washing, which can be separated and
reused. Several types of scrubber can be seen in Figure
5.13.

Spray Scrubber,
In principle pollutant gases must have a good solubility
and chemical reaction occurs with a liquid absorbent.
Usually used water as an absorber because it is cheap, not
corrosive and easy handling that can be used to absorb
particulates and SO2 gas. Alkali solution is usually used for
the separation of TRS, H2S, and Cl2 gas. Absorption
efficiency can be improved by mixing with a number of
active carbon powders. Explanation of some type of
scrubber is as follows:
