Dry & Wet Scrubber Units
DEC.XSU™
DEC provides advanced industrial Air Pollution Control (APC) solutions for the removal of acid gases, hydrogen fluoride (HF), particulate matter, aerosols, and VOCs through the DEC.XSU™ family of dry and wet scrubber systems. These systems are essential for industrial facilities that must comply with strict environmental regulations while maintaining high operational efficiency, and are typically installed upstream of a Solvent Recovery Unit or a Thermal Oxidizer to protect downstream equipment and maximize overall abatement performance.
Applications • DEC.XSU™
DEC.XSU™ is available in both dry (DEC.DSU™) and wet (DEC.WSU™) configurations, allowing treatment of the following compounds within the polluted gas stream:
- HCl – Hydrochloric acid
- HF – Hydrofluoric acid
- SO2 – Sulphur dioxide
- SO3 – Sulphur trioxide
- H2SO4 – Sulfuric acid
- H2S – Hydrogen sulfide
- CO2 – Carbon dioxide
- CO – Carbon monoxide
- NH3 – Ammonia
- Cl – Chlorine
- CCl4 – Carbon tetrachloride
- Hg – Mercury
- VOCs – Volatile organic compounds
- Sulphurous components
- Odorous compounds
- Aromatics
- Mercaptans
Dry Scrubber Unit • DEC.DSU™
The Dry Scrubber Unit (DEC.DSU™) series is designed for applications where liquid waste disposal is a concern or where the specific chemical profile of the exhaust favors a dry reagent. These systems inject dry sorbents or use specific adsorbents to react with and neutralize HAPs; the resulting dry byproduct is then captured by a high efficiency filtration system.
Wet Scrubber Unit • DEC.WSU™
The Wet Scrubber Unit (DEC.WSU™) series utilizes liquid media to intercept and neutralize pollutants from industrial exhaust. These units are particularly effective for gas streams containing soluble VOCs, acid gases, or particulate matter; they function by creating a large contact area between the gas and the scrubbing liquid.

FAQs • Frequently Asked Questions
DEC.XSU™ • Dry & Wet Scrubber Units
What is a Dry/Wet Scrubber Unit?
A Dry/Wet Scrubber Unit is an industrial air pollution control system that combines dry sorption technologies with wet scrubbing processes to remove acid gases, particulate matter, aerosols, VOCs, and hazardous pollutants from industrial exhaust streams.
Can DEC.XSU™ systems remove hydrogen fluoride (HF)?
Yes. DEC.XSU™ scrubber systems are specifically designed for high-efficiency hydrogen fluoride (HF) removal using dry absorption media, calcium hydroxide-based sorbents, structured honeycomb absorbers, and integrated wet scrubbing stages for final polishing.
Which pollutants can be treated with DEC.XSU™ scrubbers?
DEC.XSU™ systems can treat hydrogen fluoride (HF), hydrochloric acid (HCl), sulfur oxides (SOx), volatile organic compounds (VOCs), aerosols, dust, fine particulate matter, and other corrosive or hazardous industrial emissions.
What industries use dry and wet scrubber systems?
Dry and wet scrubber systems are widely used in the chemical, pharmaceutical, petrochemical, battery manufacturing, waste treatment, flexible packaging, coating, semiconductor, and industrial manufacturing sectors.
What are the advantages of dry scrubber technologies?
Dry scrubber systems reduce water consumption, minimize wastewater generation, lower maintenance requirements, and enable highly efficient acid gas treatment using reactive sorbents such as calcium hydroxide or sodium bicarbonate.
What is a dry absorption honeycomb for HF removal?
A dry absorption honeycomb is a structured porous sorption media, often based on calcium hydroxide, engineered to maximize gas-solid contact surface area for efficient hydrogen fluoride (HF) removal from industrial gas streams.
Does DEC provide custom engineered scrubber solutions?
Yes. DEC designs and supplies fully customized turnkey air pollution control systems, including dry scrubbers, wet scrubbers, hybrid scrubber units, solvent recovery systems, and VOC emission control technologies tailored to specific industrial processes.
