WET SCRUBBER

Wet Scrubber

The wet purifier consists of injecting an alkaline solution such as sodium carbonate or sodium hydroxide into a hot gas leaving a process for capturing acid gases such as HCl, HF, HBr, HI and SOx, heavy metals and semi-volatile organic compounds.

The solution is typically sprayed into a spray tower, venturi scrubber or pact tower scrubber where it reacts with acid gases while heavy metals and semi-volatile organic compounds are condensed.

The sorbent liquid is then collected at the bottom of the purifier before being recirculated to the top of the purifier or sent to a wastewater treatment unit.
