Emissions reporting: Reducing carbon footprint

March 19, 2018 Christian Markussen

With approximately six percent of the world’s carbon dioxide emissions released from cement production, the cement industry is increasing its focus on reducing its carbon footprint. Quinn Cement in Ireland has implemented a web-based reporting system to reliably measure emissions, ensuring strict adherence to environmental requirements.

The Cement Sustainability Initiative (CSI) was formed by a group of 24 major cement producers covering more than 100 countries and representing around 30 percent of the world’s cement production. A primary focus of the group is emissions measurement and reporting, and it has been instrumental in setting an expectation that all cement plants report on their emissions.

With this increasing focus to reduce the industry’s carbon footprint, a reliable and accurate means for environmental reporting is needed. The ideal reporting system should provide a quick overview of greenhouse gas emissions. Cement producers that can report accurately on their emissions not only demonstrate a commitment to reducing their environmental impact, they can also respond quickly to any changes in legislation involving mandatory reporting.

Easier environmental reporting
An environmental reporting system, such as FLSmidth’s ReportLoq™ system, collects and analyses emissions data from the analysis equipment at regular intervals. This fulfills local legislation requirements, provides trends and reports, and records comments on alarms and events.

“Analysis and reporting is a laborious, time-consuming process. In a normal cement plant, it might take about 40 million calculations in a year to crunch through the raw data. The analysis system provides all the raw data to the reporting system for calculation, and then the reporting system needs to generate automatic reports that can be sent directly to local authorities, such as the Environmental Protection Agency.” - Christian Markussen, Global Product Line Manager in Gas Analysis and Reporting, FLSmidth

Boosting efficiency
Quinn Cement has been improving its emissions reporting since late 2014, following the implementation of the ReportLoq system and a gas analysis and control system at its Ballyconnell plant. Kevin Feehan, Control & Instrumentation Engineer at Quinn Cement, explains:

“The plant needed to fulfill additional requirements in a new EPA license, which granted permission to burn waste in the form of solid recovered fuel. The system needed to record exceedances as specified in the new license. We needed to enter Quality Assurance Level 2 (QAL2) and QAL3 data and produce CUSUM charts according to the quality assurance standard EN14181.”

For Quinn Cement, one of the challenges when considering the ReportLoq system was that the data would be stored and maintained off premises. But Kevin Feehan now appreciates the benefits offered by the web-based solution, saying:

“We do not have to maintain or update the reporting system as this is carried out by FLSmidth as part of the subscription service, and we can still check on the data even though it is off-site. It is easy to operate and has saved us time producing CUSUM charts and calculating exceedance compliance.” -  Kevin Feehan, Control & Instrumentation Engineer at Quinn Cement

How FLSmidth ReportLoq works
The ReportLoq system is a web-based reporting system that enables cement plant operators and environmental coordinators to measure, collect and report emissions data. It measures data every ten seconds and stores the values for a minimum five years as required by the environmental authorities. It also provides a comprehensive report via email.

The data is stored on an onsite controller and server that collects all environmental data from the analysis equipment as raw values. These values are then transferred to the secure FLSmidth data centre, which also ensures automatic backup and eliminates the need for operating and maintaining local server solutions. The onsite server can store up to six months of data and for extra security, the controller stores data for up to 30 days.

The ReportLoq system ensures that operating technicians can monitor the current emissions values, not only as raw values, but also QAL2 and QAL3 corrected, normalised and validated values. The comments can be printed for reporting internally or externally. The ReportLoq system also provides real-time online calculations, which allows operators to monitor predicted values and avoid exceedances. The system also recognises that the values recorded during shutdown, calibration and analyser faults should not affect calculations. All these validation methods are used together with system updates, ensuring that the emissions data collected is correct and functional.

The ReportLoq system is a subscription-based system that covers all software costs associated with operation, service and maintenance of the system. The system helps organise your environmental reporting and ensures a solution that complies with the specific statutory requirements. Furthermore, the ReportLoq system has been certified by MCERTS confirming that data is handled with care and not subject to obscure or secret manipulation. Raw data is safely transferred to the FLSmidth data centre.
