GreenPrima PROCON 7000 Online Oil-in-Water Analyzer

Overview

The GreenPrima PROCON 7000 Online Oil-in-Water Analyzer is an industrial-grade, fluorescence-based optical detection system engineered for continuous, real-time monitoring of hydrocarbon contamination in aqueous streams. Unlike extractive methods requiring solvent handling or offline lab analysis, the PROCON 7000 employs a non-contact, in-situ measurement principle—exciting native aromatic compounds in mineral oils, synthetic lubricants, and fuel derivatives with UV light and quantifying emitted fluorescence intensity proportional to oil concentration. This approach delivers rapid response (<30 s typical T90), minimal maintenance, and immunity to common interferences such as suspended solids (up to 50 ppm turbidity), dissolved organic matter, and coloration—making it particularly suited for demanding cooling water circuits, condensate return lines, and regulated discharge points. Designed for integration into plant-wide SCADA and DCS architectures, the analyzer operates without reagents, consumables, or periodic calibration drift correction beyond initial factory certification.

Key Features

• Automated self-diagnostic routines including lamp intensity verification, optical path integrity check, and zero-point drift compensation
• Configurable measurement intervals from 1 minute to 24 hours, enabling adaptive monitoring aligned with process dynamics
• Intuitive 240×128-pixel resistive touch screen interface with multilingual support (English, German, French, Spanish)
• Dual independently programmable alarm outputs with adjustable delay timers (Alarm 1: 0–60 s; Alarm 2: 10–240 s) for staged response protocols
• Flexible analog output configuration: isolated 4–20 mA (min. 820 Ω load), 0–5 V or 1–5 V DC (min. 50 kΩ load), compliant with IEC 61000-6-2/6-4 EMC standards
• IP55-rated enclosure with reinforced polycarbonate front panel and stainless-steel mounting bracket for indoor industrial environments
• External control interface via screw-terminal block supporting dry-contact start/stop commands and relay-triggered alarm signaling (8 A @ 240 V AC)
• Optional USB data logging module (sold separately) enabling local CSV export of timestamped concentration values, diagnostic logs, and alarm events

Sample Compatibility & Compliance

The PROCON 7000 is validated for use with freshwater, demineralized water, low-conductivity condensate, and mildly contaminated industrial process water. It maintains measurement stability across pH 5.5–9.0 and is unaffected by common scale inhibitors or corrosion inhibitors at typical dosing concentrations. While not intended for seawater or high-salinity brines (>5,000 µS/cm), optional flow-cell conditioning kits extend applicability to moderately aggressive effluents. The instrument conforms to EN 61010-1:2010 for electrical safety and meets IEC 61326-1:2021 for electromagnetic compatibility in industrial locations. Its design supports adherence to ISO 5667-3 (water sampling), ASTM D7066 (oil-in-water by fluorescence), and EU WFD (Water Framework Directive) reporting thresholds for hydrocarbon discharges.

Software & Data Management

Data acquisition and remote configuration are supported via Modbus RTU (RS-485) and optional Ethernet/IP interfaces. The embedded firmware includes full audit trail functionality—logging all parameter changes, alarm activations, and maintenance events with UTC timestamps and operator ID fields. When integrated with GreenPrima’s optional CloudConnect gateway, historical datasets sync to secure AWS-hosted dashboards featuring trend visualization, statistical process control (SPC) charts, and automated PDF report generation. All digital communications comply with FDA 21 CFR Part 11 requirements for electronic records and signatures when configured with user authentication and role-based access control.

Applications

• Continuous monitoring of lube oil cooler leakage in gas turbine and steam turbine generator sets
• Boiler feedwater and condensate return systems—particularly where trace oil ingress risks tube fouling or phosphate hideout
• Effluent monitoring prior to municipal sewer discharge or on-site wastewater treatment plant influent
• Groundwater remediation site compliance tracking per EPA Method 1664B surrogate criteria
• Cooling tower make-up water quality assurance in petrochemical and power generation facilities

FAQ

What measurement principle does the PROCON 7000 use?

It utilizes ultraviolet-induced fluorescence (UVF) spectroscopy optimized for aliphatic and aromatic hydrocarbons present in mineral oils, synthetic esters, and diesel-range fuels.
Is the analyzer suitable for high-pressure sample streams?

Yes—it accommodates inlet pressures up to 10 bar (145 psi) and includes integral pressure regulation and flow stabilization within the wetted path.
Does it require daily calibration or reagent addition?

No. Factory-calibrated against NIST-traceable oil-in-water standards; only annual verification recommended under GLP-compliant operation.
Can it be installed outdoors?

Not directly—the IP55 rating permits installation in sheltered, temperature-controlled enclosures (e.g., instrument cabinets); outdoor deployment requires an IP66-rated weatherproof housing (accessory available).
How is sensor fouling managed in long-term operation?

The optical window features hydrophobic nano-coating and optional ultrasonic cleaning mode (activated via schedule or alarm threshold), reducing manual intervention frequency to ≤ quarterly.
