ProCeas® RNG / Biogas contaminants

Product catalog summary

Overview: The ProCeas® RNG/Biogas analyzer is designed for accurate multigas analysis in biogas applications, measuring CH4, H2O, H2S, CO2, O2, and NH3. It offers ultra-fast response times for real-time monitoring and is certified for hazardous areas.

Specifications: The analyzer measures a wide range of gases with high precision, including methane (CH4) from 0 to 100% vol, carbon dioxide (CO2) from 0 to 100% vol, hydrogen sulfide (H2S) from 0 to 1000 ppm, and others. It features a linearity of less than 1% of reading and repeatability of 3 x LOD or ± 0.5% relative.

Features and Benefits: The device supports wide dynamic measuring ranges and complies with ISO 2612:2023 for NH3 measurement. It uses patented OFCEAS® and LPS® technologies for accurate, interference-free measurements without the need for recalibration. The analyzer reduces operational costs by eliminating the need for zero or carrier gases and supports multi-point measurements.

Applications: The ProCeas® analyzer is crucial for the transition from landfill gas or biogas to Renewable Natural Gas (RNG), ensuring equipment protection and process optimization before grid injection. It provides real-time data to optimize methane quality and mitigate corrosion risks.

Technical Details: The system uses patented OFCEAS® technology combined with LPS® for enhanced absorption spectroscopy. It operates on a power supply of 110-230 VAC and is available in rack or wall-mounted configurations with specific ambient condition requirements. Communication interfaces include USB, Modbus TCP/IP, RS232, RS485, and remote access via Ethernet.

Certifications: The ProCeas® ExP is certified for hazardous areas under NEC 500/505 standards, including Class I, Zone 1, and Division 1, with various global certifications available.

The transition from landfill gas or biogas to RNG requires precise measurement of methane and impurities to ensure long-term equipment protection, and optimize the process before injection into the natural gas grid. ProCeas® RNG / biogas analyzer delivers continuous, accurate, and multigas measurement, supporting critical stages of biogas pre-treatment, purification, and grid injection. Leveraging OFCEAS® laser technology, Proceas® delivers robust, ultra-stable and interference-free measurements with minimal drift, reducing the need for calibration. This results in optimized process control,...
