The SmartCEMS® GH2 is a process online analyser for green hydrogen plants designed for continuous and simultaneous measurement of H2 and O2, in a large range of industrial applications including small to large hydrogen production plants, hydrogen and green hydrogen distribution network, H2 fuelled power stations and industrials sites. The combination of technologies (NDIR, TCD, PID, Electrochemical) and the addition of separate gas channels into the same instrument empower flexibility in multigas applications. A unique feature is to allocate a gas channel to sensible sensors. Its design ensures the cells have a limited exposure to gases and therefore extends considerably their respective life-time.
The SmartCEMS® offers multiple sensor and method configurations. Here are the measuring parameter for the most common gases. For other gases or different measuring ranges (MR), please consult us.

Typical Applications
Process gas and emissions monitoring in combustion plants, boilers, syngas, biogas, waste recycling facilities (Waste to Energy) and associated filtration systems are typical applications for the SmartCEMS® multiple gas channels configuration.
Landfills
“Landfilling” is the main method for disposal of municipal and household solid wastes or refuses in Australia. Although maintained in an oxygen-free environment and relatively dry conditions, landfill waste produces significant amounts of landfill gas (mostly methane). The Mamos enables process and air pollution emissions monitoring from solid waste landfills. Landfills operations require the control of methane CH4 and non-methane organic compound emissions (NMHC) emitted as well as an accurate online monitoring of the gas composition (CH4, CO, CO2, H2, H2S and O2). This effectively requires the collection and combustion of landfill gases. So, a good solution to the landfill gas problem is to collect it and use it to produce electricity. Landfill gas (LFG)entering the gas sampling system is saturated with water, and that water must be removed prior to further processing. The typical dry composition of the low-Btu gas is 57% CH4, 42% carbon dioxide, 0.5% nitrogen, 0.2% hydrogen, 0 to 1000 ppm of H2S and 0.2%oxygen. In addition, a significant number of other compounds are found in trace quantities. These include alkanes, aromatics, chlorocarbons, oxygenated compounds, other hydrocarbons and sulfur dioxide.
Biogas Plants
In biotechnological processes, the detailed monitoring of the fermentation product, in this case biogas, provides valuable information. Therefore, it is recommended to monitor both the volume of gas produced and the gas composition. With regard to process monitoring, a change in either gas production or gas composition can be an indicator of process imbalance.
Biogas primary constituents
- CH4 and H2S measured during the methanation process give a good overall view of the performance of the degradation process and bacterial activity. A decrease in methane content can be a first sign of organic overload, provided that the feedstock mix has not recently changed. Similarly, a sudden increase in H2S can provoke process instability.
- Simultaneous real-time monitoring of CH4, H2S and CO2 empower process automation (i.e. operation of scrubbers)
- Before entering the distribution chain, the product must be qualified, again for economic reasons (excess H2S and/or CO2 in the CH4 would make it ‘sour’ and potentially corrosive enough to damage distribution infrastructure)
- CH4, H2S, CO, CO2 and O2 Continuous Stack Emissions Monitoring required for environmental compliance
Accuracy and high reliability in harsh conditions of operations makes the SmartCEMS® a powerful optimisation tool for waste recycling facilities (incinerator, water treatment plant).
SCR and SNCR Selective non-catalytic and catalytic reductions are designed to reduce the emissions of NOx by injecting ammonia is directly injected at the combustion chamber exhaust. This process causes the nitrogen oxides to react with the ammonium and turn into nitrogen and water. The SmartCEMS® is suited to upstream and downstream SNCR/SCR monitoring and provides plants operator with accurate data to control NOx regulatory emissions while optimising the denitrification process with upstream NOx measurements.
GTC and flue gas scrubbers reduce the emissions of acid gases such as SO2 with pulverised lime powder or solutions while the discharge of heavy metals and organic pollutants is controlled with the addition of activated carbon. Online monitoring of O2, SO2 upstream of the GTC allows reducing the quantity of reagents injected.
Syngas Plants
The use of process gas online monitoring systems at locations such blast furnace gas outlet, converter off gas exhaust and coking gas outlet is very reasonable in order to analyse the fuel gases composition by measuring the concentration of CO, CO2, O2, N2, CH4, and H2. There from the calorific value BTU and the Wobbe Index WI can be accurately calculated. Modern steel plants uses dedicated stationary online monitoring system to monitor the primary constituents of Direct Reduction Iron process gases essential to have a full understanding of the process status and efficiency.
The realization of the importance of shifting from fossil fuels, both for environmental and energy security reasons, makes the use of green hydrogen extremely pertinent, as one of several potential low-carbon fuels that could take the place of fossil hydrocarbons.
To maintain safe operation, optimise the power to hydrogen conversion, and maximize the quality and purity of the produced hydrogen; the green hydrogen production process relies on measuring multiple parameters as extensively as possible and using the resulting data to inform Plant Operators.
AquaGas online analysers are suited to a large range of applications within the GH2 industry providing real time gas stream composition at key locations:
- Upstream or downstream of the electrolyser
- At mixing stations or injection points
- Along the natural gas pipeline
- At customer sites just upstream of burners
When used to their full extent, the expanded capabilities offered by accurate and reliable analysers can bring real benefits by, optimising efficiency and safety, and providing fast access to detailed data and an accurate real time overview of the operating conditions.
