Description
The OPAL-107 Phosphate Analysis System is a specialized benchtop Raman analyzer engineered specifically for phosphate mining beneficiation, wet-process phosphoric acid production, and fertilizer manufacturing. Operating at percentage-level (%) concentrations, the OPAL-107 provides direct, simultaneous quantification of phosphoric acid ($H_3PO_4 / P_2O_5$) and free residual sulfate (SO42-) in attack tank slurries and filtration liquors in under 5 minutes—eliminating 4-hour gravimetric barium sulfate digestions, operator titration errors, and massive 1:1,000 serial dilutions.
- Attack Tank Acid Balancing: Directly measures the critical balance between free sulfuric acid (H2SO4) and phosphoric acid (H3PO4) to optimize rock digestion.
- Residual Sulfate Control: Tight control of free sulfate (1.5%–3.5% SO4) prevents phosphogypsum crystal blinding and maximizes P2O5 recovery yield.
- Direct %-Level Analysis: Directly measures undiluted attack slurry filtrates and concentrated acid lines (1% to 30%+ P2O5), avoiding dilution multipliers.
- Phosphogypsum Filterability: Proper sulfate balancing ensures rapid filtration rates on tilting pan and horizontal belt filters, eliminating production bottlenecks.
- Rapid Shift Control: Provides actionable analytical feedback in under 5 minutes right in the plant control room, replacing 4-hour gravimetric lab turnarounds.
- OPAL Benchtop Spectrometer: Solid-state Raman optical measurement unit with enclosed sample measurement port.
- Universal AC Power Adapter: 100–240 VAC, 50/60 Hz power supply with standard IEC power cord.
- USB Data Interface Cable: High-speed shielded connection to host PC or laptop.
- OndaVia Quantitative Raman Software: Factory-calibrated for %-level phosphoric acid and free sulfate speciation with automated reporting.
- Solid-State Verification Standard: Reusable optical reference standard for routine instrument calibration check.
- Documentation Package: Industrial operating manual, safety protocols, and factory certificate of calibration.
