Advantages of Online Gas Analysis System

Continuous real-time monitoring
Delivers instantaneous, 24/7 tracking of gas concentrations. Operators can observe rate-of-change trends immediately rather than waiting for discrete laboratory test results.
Reduced operational costs
Minimizes the need for manual sampling, routine laboratory testing, and emergency interventions. It substantially reduces losses associated with production downtime.


Predictive maintenance
Catches developing issues early, allowing for proactive, scheduled repairs before catastrophic failures occur.
Enhanced safety
Eliminates the need for personnel to manually collect samples in high-risk or hazardous zones, vastly improving workplace safety.

Features of Online Gas Analysis System

Comprehensive & accurate – real-time calorific value included: Fuses ndir, tcd, and electrochemical sensors to cover all 7 key gases with ±1% f.S. Accuracy (±1.5% for o₂/h₂s). Automatically computes higher/lower heating value (hhv/lhv)-data ready for combustion control, energy billing, or carbon reporting.
Advanced pre-treatment – long-term, low-maintenance operation: Maintenance-free corrosion-resistant probe with multi-point sampling. Patented dual-directional energy-assisted back-purge prevents clogging.
Triple-stage filtration: Removes dust, moisture, and tar simultaneously. Rapid condensation + bypass design minimizes adsorption loss and accelerates response time.
Fully customizable & easy to integrate: All gas ranges (e.G., co 0–60%, h₂ 0–100%, h₂s 0–100 ppm) can be tailored to your process. Standard 4–20 ma and rs-485 outputs ensure seamless integration with dcs, plc, or plant-wide control systems.
Plug-and-play deployment – low total cost of ownership: Modular design with factory pre-integration and calibration-minimizes on-site commissioning time. High automation reduces manual intervention, while no consumable filters or reagents keep long-term operating costs low.
Application of Online Gas Analysis System
Steel & Metallurgy: Real-time monitoring of blast furnace gas (BFG), converter gas (LDG), and coke oven gas (COG) for safe recovery, pipeline integrity, and optimal combustion in reheating furnaces.
Coal-to-Chemicals: Precise analysis of syngas (H₂, CO, CH₄, CO₂) in methanol, ammonia, or olefin plants-ensuring reaction stoichiometry and tail-gas emission compliance.
Power & Energy: Gas composition monitoring in IGCC (integrated gasification combined cycle) and waste-heat boiler systems to maximize boiler efficiency and turbine safety.
Waste-to-Energy & Biomass: Continuous analysis of biogas or landfill gas, with early warning for H₂S corrosion, enabling protective measures and combustion tuning.
Glass, Ceramics & Building Materials: Stable kiln temperature control via real-time calorific value and O₂ feedback, improving product quality and reducing fuel consumption.
