Perindustrian Acid Gas Scrubbing:
Maximum Corrosion Resistance & 99% Efficiency
Tailored engineering solutions for HCl, HF, SOx, Cl2, and H2S. Utilizing advanced FRP/PP materials dan Smart pH feedback loops to ensure absolute compliance with the strictest emission thresholds.
Why Acid Gas Demands Specialized Engineering
Acid gases such as Hydrogen Chloride (HCl) and Hydrogen Fluoride (HF) are not just atmospheric pollutants; they are "equipment killers." When these gases condense, they create a highly corrosive environment that leads to rapid pitting, stress corrosion cracking, and structural failure of standard metal components.
When treating Halogenated VOCs (chlorinated or fluorinated solvents), the RTO combustion process irrevocably converts these organic molecules into acidic byproducts. Therefore, a Post-RTO Scrubber is a mandatory system standard to protect the stack and fan.
Stopping rapid oxidation of ductwork and downstream fans.
Achieving mg/Nm3 thresholds for inorganic acid compounds.
Integrated System Logic
This system exemplifies the "Second Half" of halogenated VOC treatment. After the RTO thermal process breaks the organic bonds, the resulting acid gas must be immediately neutralized. Our post-RTO scrubbers utilize rapid-quench cooling and chemical absorption to ensure that the final exhaust is both solvent-free and non-acidic.

Wet Packed Bed Scrubbing
Our primary defense for high-concentration acid gas streams. Utilizing counter-current chemical absorption, toxic gases and alkaline neutralization liquids interface within high-surface-area packing media. This design ensures a consistent neutralization efficiency of 99% or higher for substances like HCl and HF.
RTO + Post-Scrubbing Integration
Specifically engineered for halogenated VOC streams. After thermal oxidation in the RTO, acidic byproducts are immediately addressed in the post-treatment scrubber. Built with corrosion-proof materials (FRP/PP) to eliminate acid-dew-point corrosion and ensure long-term structural integrity.
