Complete primary and secondary NOx abatement solutions designed to handle both high-temperature furnace gases and ambient wet exhaust streams.

Key Features

1. Flexible High-Efficiency Primary Reduction (SCR / SNCR): Operates upfront at high temperatures (850°C-1,100°C for SNCR; 150°C–400°C with catalyst for SCR) to reduce the bulk load of NOx into harmless nitrogen gas (N₂) and water.

2. Integrated Downstream Wet Scrubbing: Seamlessly paired with a quencher and multi-stage chemical scrubber downstream to capture unreacted ammonia slip, scrub residual acid gases, and eliminate yellow/brown NO₂ plumes.

3. Multi-Stage Oxidation & Reduction: Utilizes automated chemical oxidation/reduction loops to neutralize remaining insoluble NO and NO₂ fractions into harmless dissolved salts.

4. Smart Reagent Control & Safety: Automated temperature tracking, ORP/pH sensors, and precision metering skids to optimize reagent consumption (urea/ammonia/oxidizer).
