Description
The ORCA-303 Triazine Analysis Unit is a fully integrated, automated on-line process analyzer engineered for continuous speciation and quantification of triazine-based H2S scavengers in natural gas processing, pipeline gathering, and crude production. Combining an industrial electronic controller, solid-state Quantitative Raman Spectrometer (QRS), and automated slipstream fluidic sample preparation in a single industrial enclosure, the ORCA-303 resolves active MEA- and MMA-triazine from spent dithiazine byproducts—feeding real-time telemetry to your plant DCS to close the loop on chemical injection and eliminate chemical over-dosing.
- Active Scavenger Speciation: Simultaneously quantifies unreacted MEA-triazine and MMA-triazine concentrations directly from contactor effluent or pipeline slipstreams.
- Spent Byproduct Tracking: Measures dithiazine reaction byproduct formation to verify complete scavenger utilization and prevent reboiler solids precipitation.
- Closed-Loop DCS Control: Provides real-time concentration telemetry via Modbus TCP/IP and 4–20 mA to automatically modulate chemical injection pump stroke rates.
- Quality Control of Raw Chemistry: Validates incoming bulk scavenger deliveries to detect substandard, diluted, or off-spec chemical shipments before injection.
- Environmental & Safety Assurance: Guarantees gas stream pipeline tariff compliance (< 4 ppm H2S) while eliminating technician exposure to toxic sour fluids.
- All-in-One Enclosure: Houses both the central computing/optical engine and the automated microfluidic sampling system in a single pre-tested package.
- Automated Slipstream Extraction: Connects to process slipstream with programmable line flushes to guarantee fresh sample representation.
- Automated Self-Cleaning Flow Cell: Programmed solvent rinse cycles prevent optical window fouling and eliminate cross-contamination between test runs.
- Bulk Reagent Reservoir: Shipped with a 4-L bulk reagent container designed for high-frequency automated sampling with minimal technician touch.
- Optional Touchscreen Display: Available with an integrated industrial front-panel display for on-unit trend monitoring and local diagnostics.
