Chlorine (Cl₂), Hydrogen Sulfide (H₂S) Sulfur Dioxide (SO₂), Hydrogen Chloride (HCl) and Ammonia (NH₃)

Our emergency scrubber systems typically consist of a combination of scrubbing technologies functioning in series. Many systems utilize eductor venturi scrubbers, packed towers and other stages mounted on a chemical storage tank. The tank holds sufficient neutralizing chemical to absorb and neutralize a release of toxic gas at a very high inlet concentration and flow rate.

Aerosols as extremely fine liquid droplets can be formed from gas phase hydrolysis of halogenated acids (HCl, HF, HBr), metal halides, organohalides, sulfur trioxide (SO₃), and phosphorous pentoxide (P₂O₅). Entrained liquid droplets are much larger than aerosols and are usually produced by drag-off or collection from a processing tank involving dipping or mixing operations. Typical examples are sulfuric acid (H₂SO₄), nitric acid (HNO₃), and sodium hydroxide (NaOH) from metal finishing/cleaning operations.

Oil Process (Refineries and Petrochemicals)

Most volatile organic compounds, or VOCs, are not appreciably soluble in water or reactive with standard aqueous chemical solutions. This class covers a wide range of compounds including Toluene, Styrene, and many chlorinated solvents. Wet scrubbing is not considered an effective means for removal of these compounds and technologies such as thermal oxidation or carbon adsorption are required for effective removal. However, when halogenated compounds are oxidized, the resultant stream contains hydrogen chloride gas that needs to be removed using wet scrubbing technology.  Due to their low water solubility, VOCs can be desorbed or stripped from contaminated liquid solutions. Packed towers are an effective equipment choice for this application.
