Burn-Wet Abatement System

Burn-wet, plasma, and thermal abatement units each neutralize hazardous process exhaust gas through a different destruction mechanism, matched to whatever specific chemistry a given process actually exhausts — combustion followed by a water wash, an electrically-sustained plasma, or straightforward thermal decomposition.

Process exhausts hazardous, flammable, or toxic gas that can't release untreated
Different gas chemistries need different destruction methods
Abatement method
Burn-wet
Combusts the gas, then washes resulting byproducts with water
Plasma abatement
Electrically sustained plasma breaks down gas molecules directly
Thermal abatement
High-temperature decomposition without a sustained flame or plasma
Hazardous gas converted to safe, releasable byproducts
Specific method chosen to match the exhaust gas chemistry

Burn-wet abatement's two-stage design exists because combustion alone often leaves behind acidic or particulate byproducts that still need treatment before release. The burn stage destroys the hazardous gas through combustion, converting it into simpler combustion products; those combustion products — which can include acid gases or particulates — then pass through a water wash stage that neutralizes and removes them before the exhaust is finally released, making burn-wet a two-step process specifically because the first step alone wouldn't produce a fully safe exhaust stream.

Abatement Methods — Matched to the Exhaust Chemistry burn-wet's two stages, plasma's direct breakdown, thermal's simplicity Burn-wet — two stages combustion water wash combustion byproducts need the wash step too Plasma and thermal — single-stage plasma thermal direct molecular breakdown, no separate wash stage needed method choice is matched specifically to the chemistry of the exhaust gas being treated

Plasma abatement's direct molecular breakdown avoids burn-wet's combustion byproduct problem entirely, which is part of why it's favored for certain gas chemistries where that two-stage treatment isn't the best fit. An electrically sustained plasma breaks apart hazardous gas molecules directly through energetic collisions rather than combustion, often producing a different, more easily managed byproduct profile than burning the same gas would — the right choice specifically for exhaust chemistries where plasma's breakdown mechanism handles that particular gas more cleanly than burn-wet's combustion-then-wash approach.

Burn-wet, plasma, and thermal abatement all exist as distinct destruction mechanisms because no single method handles every hazardous exhaust gas chemistry equally well, and a fab's choice among them reflects exactly which specific process gases a given exhaust line is actually carrying.
