Venturi, packed-bed, and spray-tower wet scrubbers, plus dry sorbent injection systems, engineered to strip SOx, H₂S, ammonia, CO₂ and particulate matter from process and stack gas before it reaches the atmosphere.
A scrubber removes gaseous and particulate pollutants from an exhaust or process gas stream before it's released to atmosphere. Wet scrubbers use water or a formulated liquid reagent brought into intimate contact with the gas to absorb or neutralize contaminants — effective on both gases and particulates simultaneously, and inherently fire-safe since the pollutant stream stays wet throughout. Dry scrubbers instead inject a powdered alkaline sorbent — hydrated lime, sodium bicarbonate, or sodium sesquicarbonate — that reacts with acidic gases before being captured downstream in a fabric filter or electrostatic precipitator, producing a dry waste that needs no wastewater treatment.
Fintelius selects the technology — and within wet scrubbing, the specific contact mechanism — against the pollutant mix, particulate loading, and available plot space, then engineers the vessel, packing or venturi throat, and reagent system as a complete, code-compliant package.
Every scrubber follows the same disciplined path through design and fabrication, whatever technology is selected.
Gas composition, particulate loading, and required removal efficiency are analyzed against applicable emissions limits.
Wet (venturi, packed-bed, spray tower) or dry sorbent injection is selected against the pollutant mix, plot space, and utility availability.
Shell, packing supports, spray headers, or venturi throat are fabricated in corrosion-resistant materials matched to the reagent and gas stream.
Liquid or dry sorbent delivery systems, recirculation pumps, and process instrumentation are integrated and commissioned.
The complete system is tested against design removal efficiency, then coated and prepared for shipment or field erection.
A constricted throat accelerates the gas stream, atomizing injected liquid into fine droplets for intense mixing — excellent for fine particulate (PM10/PM2.5), at a pressure drop of roughly 10–25 in. w.c.
A vertical column of packing material provides extended wetted-surface contact between rising gas and falling liquid — highly effective for SO₂, HCl, ammonia & VOCs at a much lower pressure drop of roughly 1–6 in. w.c.
Liquid reagent is sprayed directly into the gas stream for gas-phase absorption — a simpler, lower-maintenance configuration for moderate removal-efficiency duty.
Dry sorbent injection trades some removal efficiency for a dramatically simpler downstream waste stream.
Exhaust gas is conditioned to the optimal temperature range for sorbent reactivity before reagent injection.
Hydrated lime, sodium bicarbonate, or sodium sesquicarbonate is injected to react with SO₂ and HCl in the gas stream.
Spent sorbent and reaction products are captured downstream in a baghouse or electrostatic precipitator, producing a dry, easily handled waste.
No wastewater treatment system required, making dry scrubbing well suited to space-constrained retrofits of existing facilities.
Absence of recirculating liquid and slurry handling reduces the maintenance burden relative to wet systems.
Lighter powder waste and no wastewater disposal typically reduce total operating cost versus a comparable wet system.
