Reduce emissions of atmospheric pollutants with gas analysers .

Fuji Electric, a global expert in gas analysis, has developed a strategy to help manufacturers reduce their carbon footprint through four strategies:

• combustion optimization,
• gas purification (such as DeNOx treatment by selective catalytic reduction (SCR), DeSOx treatment by flue gas desulphurization (FGD) and carbon storage and capture),
• monitoring atmospheric emissions
• the development of clean, renewable energies.

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.

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.

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 Cleaning and Carbon Capture: Essential Technologies for a Cleaner Environment

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.

analyser for DeNOx treatment

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.

analyser for flue gas desulphurization DeSOX

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.

analyser for carbon capture and storage (CCS)

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.

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.

This measuring device is a state-of-the-art technical solution for accurate detection and monitoring of hydrogen in the various stages of its production. Offering constant monitoring of gas concentrations, this analyser ensures atmosphere regulation in critical installations such as hydrogen generators and steam reforming processes. Theanalyser ZAF guarantees the high precision essential for maintaining the quality of the hydrogen produced.

analysers gases play a vital role in the development of clean and renewable energies by ensuring accurate and reliable emissions monitoring, essential for optimizing processes and guaranteeing the environmental efficiency of emerging energy technologies.
