Description
The ORCA-205 Formaldehyde Analysis Fluidic Unit is an automated sample conditioning and fluidic presentation module engineered to operate with the ORCA-101 Electronic Control Unit. Designed for continuous, on-line process monitoring, the ORCA-205 automatically draws slipstream samples containing simple aldehydes, alcohols, and biocides, executes precision chemical conditioning, and feeds the sample into the Quantitative Raman Spectroscopy (QRS) flow cell—enabling automated, closed-loop chemical dosing control without hazardous manual derivatizations or slow off-site gas chromatography.
- Formaldehyde Monitoring: Continuous quantification of free formaldehyde in industrial resin manufacturing, chemical synthesis, and H2S scavenger production.
- Pipeline Hydrate Inhibition: On-line tracking of methanol (CH3OH) and monoethylene glycol (MEG) in raw natural gas gathering lines and subsea tiebacks.
- Oilfield Biocide Dosing: Automated concentration verification of active tetrakis(hydroxymethyl)phosphonium sulfate (THPS) and glutaraldehyde in waterflood operations.
- Solvent & Alcohol Tracking: Configurable methods available for acetaldehyde, ethanol, and industrial ketone streams.
- High Salinity Tolerance: Reliable optical measurement in heavy oilfield brines and produced water without chromatographic column fouling.
- Automated Slipstream Sampling: Direct slipstream tap with automated line purging to eliminate stagnant sample artifacts.
- Microfluidic Reaction Mixing: Reagent metering pumps ensure stoichiometric precision across fluctuating plant ambient temperatures.
- Automated Flow-Cell Rinse: Self-cleaning optical chamber executes automated solvent flushes between test cycles to prevent carryover.
- Extended Reagent Autonomy: Standard plug-and-play reagent packs deliver 168 automated runs (1 test/hr for 7 days); bulk reservoir available for 30-day walkaway operation.
- SCADA / DCS Transmission: Governed by the ORCA-101 central processor to output calibrated ppm values directly to plant control systems via Modbus and 4–20 mA.
