analysers gases are essential to ensuring greener industrial activities, particularly in chemical plants, cement works, metallurgy and the food industry. They are also essential for the production of current clean energies and future renewable energies. By optimizing the monitoring and control of emissions, gas analysis contributes to the reduction of atmospheric pollutants and greenhouse gas (GHG) emissions, thus promoting a healthier environment that respects nature.
The reduction of CO2 and other greenhouse gas emissions remains a concern for manufacturers. In the context of a global tightening of environmental regulations, actions to limit the climate impact have gained new momentum.
For example, the reform of the carbon market adopted by the European Parliament in April 2023 aims for a 62% reduction in emission allowances for industry by 2030 compared with 2005, illustrating a marked desire to accelerate the ecological transition.
Global initiatives such as the Paris Agreement continue to play a pivotal role in raising awareness and mobilizing against global warming. In response, pressure on manufacturers to minimize their polluting emissions and actively engage in eco-responsible practices is growing.
Recent statistics underline this trend, showing a significant drop in emissions in the industrial sector, thanks in particular to increased investment in clean and renewable energies.
Gas analysis is an invaluable tool in this fight against climate change, offering companies a means of quantifying and effectively reducing their harmful emissions. This approach not only contributes to better environmental compliance, but also helps optimize industrial processes for less energy-intensive, more sustainable production.
Fuji Electric, a global expert in gas analysis, has developed a strategy to help manufacturers reduce their carbon footprint through four strategies:
By combining gas analysis solutions, industrial companies can make their operations more environmentally friendly. They also optimize their processes. This dual advantage enables them to reduce energy consumption and increase production yields.
To generate the thermal energy required for industrial processes, boilers use combustion reactions, which mix fuel with oxygen from the air to induce an exothermic reaction. This reaction releases energy in the form of heat, which is then transferred to the heat transfer fluid, usually water or steam, circulating through the boiler systems.
However, these boilers require large amounts of fuel, present potential safety hazards and produce harmful emissions such as carbon dioxide (CO2).
Before the introduction of analysers gas, these heating systems had a high fuel-oxygen ratio in excess of air to avoid dangerous conditions that could lead to explosions. This method was highly inefficient and increased fuel consumption. What's more, excess oxygen (O2) also reacts with the nitrogen and sulfur present in the fuel, generating undesirable emissions such as nitrogen oxides (NOx) and sulfur oxides (SOx).
Accurate analysis of gases, especially O2 and combustion compounds such as carbon monoxide (CO), is essential. It helps optimize the ratio between air and fuel. This ensures a more efficient stoichiometric combustion reaction.
Combustion control helps industrial companies meet environmental standards. This involves reducing fuel consumption, which in turn leads to lower emissions of NOx, SOx and CO. At the same time, it reduces CO2 emissions.
Zirconium oxide-based analysers combustion technology has long been recognized for monitoring oxygen concentration in combustion. One example is Fuji Electric'sZFK/ZKM combustion monitoranalyser , which delivers reliable and accurate results. What's more, it reacts quickly to changes in combustion conditions, such as fluctuations in gas flow, pressure and temperature.
PSC process controllers can be easily added to provide a complete combustion control solution to optimize combustion and safety on your industrial boiler.
Adjustable laser diode (TDL) technology offers even faster measurement, especially for CO, by providing an average over the measurement path rather than a single-point result.
Fuji Electric'sanalyser dual-beam CO + O2 gas sensor ZSS-6 offers an all-in-one solution for this application, being able to be configured to measure both oxygen (O2) and carbon monoxide (CO) without the need for separateanalysers .
It can also be combined with a CH4 methane measurement, providing a fast-response measurement for safety in natural gas-fired heaters and boilers.
Gas analysis plays a vital role in optimizing combustion. Efficient combustion minimizes the production of harmful emissions, contributing to better air quality and a cleaner environment.
It also improves the energy efficiency of boilers, significantly reducing fuel consumption. This mechanism has a direct effect on reducing operating costs in plants.
Beyond boilers, this practice finds use in a variety of industrial applications, such as industrial furnaces, gas turbines, internal combustion engines, as well as in processes requiring high-temperature heating.
Sectors such as cement production, metallurgy, power generation, pulp and paper, and the chemical and petrochemical industries also benefit from optimized combustion management.
Improved energy efficiency, reduced emissions and better temperature control mean safer, more economical and more environmentally-friendly operations.
The analysers are the cornerstones of gas cleaning. This practice consists of filtering pollutants and removing harmful substances from process gases and fumes before they are emitted by industries.
Typical gas cleaning processes include:
DeNOx treatment by selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR): This process aims to reduce the nitrogen oxides (NOx) present in flue gases, often using ammonia or urea as a reductant. An excessive quantity of reagent escapes up the chimney in the form of ammonia.
DeSOx treatment by flue gas desulfurization (FGD): This technique removes sulfur dioxide (SO2) from flue gases, a key process in the fight against acid pollution. This wet flue gas treatment is often carried out by injecting a lime or limestone suspension into the gases to precipitate SO2 in the form of sulfate.
Carbon Capture and Storage (CCS ): This process involves capturing carbon dioxide (CO2) from industrial or energy processes, transporting it to a storage site (usually underground in former oil or gas fields) and disposing of it safely.
By capturing and storing CO2, these technologies prevent the emission of this greenhouse gas into the atmosphere, thereby helping to combat climate change. They also offer the possibility of reusing the captured CO2 in other industrial processes.
When it comes to DeNOx treatment, which aims to reduce nitrogen oxide (NOx) emissions into the atmosphere, analysers gases play a key role.
In particular, measurement of excess ammonia (NH₃) using analysers tunable diode lasers (TDL) such as theanalyser gas laser ZSS, plays a critical role in fine-tuning chemical treatment in purification processes.
These analysers gases provide a highly accurate assessment that not only guarantees the efficiency of SCR and SNCR systems, but also prevents the build-up of NH₃ that can lead to deposits and equipment corrosion.
To take things a step further, Fuji Electric's analysers infrared gas monitors are distinguished by their ability to measure NOx and SOx levels simultaneously. These devices enable much more rigorous and comprehensive control of emission quality, and facilitate fine-tuning of the purification process.
Theanalyser gas is essential for flue gas desulphurization (DeSOx), a critical practice for minimizing pollutant emissions from industrial plants.
In particular, new-generationanalyser tunable diode laser (TDL) technology, such as that developed by Fuji Electric, offers an advanced solution for this application. These analysers devices enable continuous, in-situ monitoring of sulfur dioxide (SO2) emissions for the control and optimization of DeSOx processes.
The benefits of analysers for DeSOx flue gas desulphurization are manifold.
Firstly, their ability to provide accurate, real-time SO2 measurements enables operators to quickly adjust the desulphurization process to ensure maximum efficiency, thus minimizing reagent consumption and operating costs.
Secondly, thanks to their direct in-situ measurement technology, these analysers reduce the risk of errors associated with sample collection and transport, improving data reliability.
What's more, the robustness and simplified maintenance of these systems guarantee high availability and a long service life, reducing unplanned downtime and maintenance costs.
These methods aim to reduce CO2 emissions by capturing this greenhouse gas at source, for example in power plants, and then storing it underground or at sea. To this end, analysers are proving to be indispensable tools for optimizing these CO2 capture and storage processes.
Among the technologies available, Fuji Electric'sanalysers infrared gas analyzers stand out for their exceptional ability to monitor gas composition in minute detail.
This advanced equipment is capable of accurately detecting various gaseous components such as CO2, both at percentage concentrations and at parts-per-million levels.
This accuracy is fundamental to measuring the efficiency with which flue gases are treated, ensuring that a maximum amount of CO2 is captured. In addition, these analysers are essential in the assessment of CO2 purity prior to storage, thus ensuring the long-term safety and effectiveness of CCS.
With the fight against climate change an international priority, regulations on greenhouse gas emissions (carbon dioxide CO2, methane CH4, nitrous oxide N2O) are becoming increasingly stringent worldwide. The same applies to pollutants such as nitrogen oxides NOx, sulfur oxides SOx and carbon monoxide CO, which are harmful to the environment.
Monitoring emissions from combustion is now mandatory, not only to meet environmental standards, but also to save our planet.
By monitoring these emissions, industries can show they care about the environment and reduce their carbon footprint.
To guarantee regulatory compliance, a Continuous Emissions Monitoring System (CEMS) is essential to measure all the necessary components of industrial air emissions. This system must offer precision and repeatability when measuring multiple pollutants.
Fuji Electric's analysers gas analyzers use a variety of detection technologies to measure gas components. Depending on the industrial application, these analysers gas analyzers can either provide all the necessary measurements in a single instrument, or use different technologies integrated into a complete custom gas analysis system. For example, theanalyser infrared ZKJ multi-gas can monitor five gases simultaneously, with a choice of components from O2, CO2, CO, SO2, NO, CH4 and N2O.
To keep up with regulatory requirements on industrial emissions, the adoption of MCERTS and QAL1 certified gas analysis systems is becoming imperative. This certification guarantees accurate and reliable measurement of emissions, an essential criterion for industrial plant operators wishing to comply with current environmental standards.
Combined with Fuji Electric's data acquisition and processing system, regulatory air emissions data, calculations and reports can be reported to the authorities.
In a world in constant search of clean, sustainable energy sources, hydrogen (H2) production is at the heart of energy innovation.
Industries are diversifying their energy sources by aggressively integrating hydrogen into their production chains to meet growing demand.
