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.
Boosting efficiencyQuinn 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.
