Biogas analyzer ProCeas®

natural gaswaterammonia

Product Overview
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, reduced maintenance costs, and superior gas quality assurance.

By offering real-time data, Proceas® helps operators optimize methane quality and yield while mitigating corrosion risks, making it an invaluable tool for the renewable gas sector. The implementation of advanced continuous, real-time, multigas analyzers marks a significant advancement in efficient and environmentally responsible management, particularly in
upgrading methane gas produced from landfills and agriculture.

Benefits

• Long-lasting accuracy: On-line measurement, with no need for re-calibration or sensor replacement
• Reduced operational costs and complexity: Multi-point measurement, no zero gas or carrier gases required, easy to use with low maintenance
• Helps protecting infrastructure: Identifies contaminants in real-time enabling process adjustments that reduce maintenance costs for carbon beds, pipelines, turbines, etc.
• Fast decision-making: Real-time, accurate data supporting process control and gas quality assurance

Features
