Air Monitoring


Given the linguistic diversity in regions like the EU, multilingual support in DAHS is vital. The ability to switch between various languages enhances the system’s usability across different countries. Tracking Key Performance Indicators (KPIs) such as availability, operating time, analyser drift, relative accuracy, bias, uncertainty, linearity, device failures, maintenance, over range events, emission exceedances, energy, and emission rates is fundamental in assessing the system’s performance and reliability.


The system also allows unlimited tags and buffer storage, ensuring the security of all data for the project’s lifetime. Enhanced CEMS maintenance involves tracking diagnostics from instruments, generating alarms, sending emails, and performing corrective actions. The system can also function as a backup for the process control system. The capability to generate reports in multiple formats and upload them to FTP enhances the versatility of the system.


Expandability and fl exible hardware options mean that the system can combine emission sources cost-effectively, which centralises emissions data for easier reporting. The absence of a PLC requirement reduces associated costs and complexity.


Integrating automatic QAL 3 into CEMS DAHS signifi cantly improves reliability and effi ciency. This ongoing quality assurance process maintains the operational integrity of CEMS by ensuring compliance with required zero and span drift values. The process streamlines QAL 3 procedures, eliminating the need for manual intervention, thus offering cost-effective solutions.


Control charts like CUSUM, Shewhart, and EWMA are integral to QAL 3. They play a vital role in monitoring the performance of remote analysers, analysing instrument zero and span calibration checks, and detecting measurement drift within permissible limits. This continuous analysis is essential for swiftly identifying and correcting calibration errors or biases.


Automatic QAL 3 in CEMS DAHS not only improves the system’s reliability, but also ensures sustained compliance with evolving environmental standards and regulations. This technological progress signifi es a commitment to cleaner emissions and better air quality, refl ecting the ongoing evolution in environmental monitoring systems.


Predictive Emissions Monitoring (PEMS) plays a crucial role in enhancing the reliability of CEMS. PEMS can be used to backfi ll missing or invalid data and aid in forecasting future emissions, thus facilitating process optimisation and compliance. This predictive capability is integral in maintaining the high standards of emissions monitoring required by current regulations.


The enhancement of DAHS reliability as per EN 17255 is not just a regulatory requirement. It is a strategic investment in environmental stewardship. By implementing advanced data processing techniques, ensuring data immutability and redundancy, and integrating systems like PEMS, industries can achieve a high degree of accuracy and reliability in emissions monitoring. As environmental regulations become increasingly stringent, the role of robust and reliable DAHS will become ever more critical in ensuring compliance and protecting our environment.

Frost & Sullivan hand out award for excellence in emissions monitoring


This year’s Frost & Sullivan award for vision, innovation and technical expertise in emissions monitoring and methane gas leak detection has been won by ABB, in recognition of their best-in-class portfolio of intelligent instrumentation and sophisticated gas analysis technology, along with the Swiss company’s efforts in supporting industrial carbonisation. Frost & Sullivan’s international panel of growth pipeline experts picked ABB because of its visionary grasp of future global challenges, the implementation of best practices and strategic analytics. The panel also considered ABB’s proud track in developing cutting-edge emissions monitoring technology that has moulded industry trends and supported customers in conforming to ever more strict emissions regulations across the globe.


Jean-René Roy, Global Business Line Manager of ABB Measurement & Analytics stated, “There has been a long-term commitment from ABB to the development of multiple innovative emissions monitoring and gas leak technologies that serve the broadest industry sectors worldwide. It is fantastic that Frost & Sullivan has recognised our collective achievement and leading technology through this award, and I would like to thank my team for their continued dedication to the cause.”


Carbon-intensive organisations need effi cient emissions management and reduction solutions more than ever to combat the impact of greenhouse gas emissions and comply with environmental legislation. The EU has recently passed a regulation to reduce methane emissions from energy companies, in the US, legislation stipulates that oil and gas companies must measure methane emissions precisely.


ABB has an impressive array of technology that helps industries across the globe achieve fast, precise, and reliable data to enable them to take action to avoid polluting the environment, along with the legal action and negative publicity that follows. Cutting-edge hardware including the ACF5000 is the cornerstone of innovation at ABB Measurement & Analytics. ABB also offers the drone-based HoverGuard™ which is capable of measuring methane emissions down to one part per billion (ppb). ABB’s MobileGuard™ solution detects, maps, quantifi es and localises natural gas leaks in a moving vehicle. ABB provided the interferometer to the Japanese GOSAT program and optical sensors to the GHGSat project to pinpoint individual industrial facilities’ carbon dioxide emissions from space. ABB’s portfolio also includes condition monitoring solutions to enable the early identifi cation of equipment issues saving industrial plants valuable time and money.


According to Frost & Sullivan, ABB’s highly advanced, digitally enabled devices and solutions for measuring industrial processes and greenhouse gas emissions, detecting gas leaks, and optimising production achieve cost-effective compliance and effi ciency on a long-term basis.


ABB’s extensive range of instrumentation and gas analysis technology also includes continuous emissions monitoring systems (CEMS) used in a wide variety of industrial applications. ABB’s range also boasts the inclusion of ABB Ability™ Natural Gas Leak Detection Solutions, a comprehensive suite that detects and maps gas leaks with unsurpassed precision.


To achieve collective, coordinated action across the globe, the United States Department of Energy has awarded ABB a grant to develop a single repository platform that will, for the fi rst time, aggregate, analyse, and visualise methane data from multiple sources. This project will facilitate a considerable drop in methane emissions, pollution, and waste, achieving remarkable progress in reaching climate change targets.


ABB’s technology is also being used to overcome the huge environmental catastrophe caused by millions of leaking orphan oil and gas wells across the USA; their extremely sensitive analysers, featuring state-of-the-art OA-ICOS™ laser-based technology can detect methane emissions from decommissioned wells down to one ppb.
