Description
The ORCA-202 Ammonia Analysis Fluidic Unit is an automated on-line sample preparation and fluidic control module designed for pairing with the ORCA-101 Electronic Control Unit. Engineered for continuous, unattended chemical monitoring, the ORCA-202 extracts slipstream samples from industrial process water and wastewater lines, performs automated reagent conditioning, and delivers conditioned samples to the Quantitative Raman Spectroscopy (QRS) flow cell—providing continuous ammonia ($NH_3 / NH4+$) tracking without manual colorimetric kits or ion-selective electrode drift.
- Refinery Sour Water Strippers: Continuous monitoring of SWS stripper bottoms to verify complete ammonia removal before downstream biotreatment.
- Industrial Wastewater Discharge: High-frequency automated ammonia compliance tracking to prevent regulatory exceedances and municipal surcharges.
- SCR / SNCR DeNOx Systems: Real-time detection of ammonia slip in scrubber liquors and wet flue gas desulfurization systems.
- Cooling Water Treatment: Tracks ammonia contamination and microbial nitrification kinetics in industrial recirculating cooling loops.
- Robust Matrix Tolerance: Unaffected by background turbidity, suspended solids, heavy oils, or high salt concentrations that foul optical colorimeters.
- Automated Slipstream Conditioning: Pulls fresh samples on an automated schedule with internal line purge to eliminate stale fluid artifacts.
- No Membrane Fouling: Unlike ion-selective electrodes (ISE), the optical Raman flow-cell does not suffer from glass degradation, calibration drift, or membrane fouling.
- Automated Cell Cleaning: Programmed wash cycles flush the measurement cell between test runs to guarantee high spectral reproducibility.
- Extended Reagent Autonomy: Standard reagent packs provide 168 automated runs (1 test/hr for 1 week); bulk reservoir configurations available for monthly intervals.
- Direct Integration with ORCA-101: Central controller translates spectra into calibrated ppm values and outputs directly to DCS via Modbus and 4–20 mA.
