The objective of the Real-Time Emissions Monitoring System (FS-EMS) from emission sources is to provide a custom and predesigned analytical tool which utilizes existing infrastructure, measures, and reports accurately the species-wise emission volumes by identifying sources in real-time via a corporate-wide web-based system. FS-EMS provides the companies a wider and clear vision of their sources connected to flaring/emission stacks and facilities, which will be particularly important for taking preventive and corrective actions based on system-generated reports, alerts, notifications, and KPIs.

FS-EMS allows performing a direct real-time data transfer between one or more DAHS which can further be interfaced with other DAHS, DCS, SCADA systems, data loggers, etc., connected to a company network.

FS-EMS incorporates a new and unique system that generates accurate, real-time presentation and detailed reporting of emission events from every source of a facility. The FS-EMS allows for monitoring of all emission sources at multiple processing facilities, with multiple plants, by utilizing existing plant real-time measurements of flows, pressures, temperatures, compositions, and other available process variables of control valves, monitoring devices, and any manual devices responsible for the facility emissions. By monitoring source-wise actual emission measurements, operators will be able to optimize the operation of their plants more effectively, resulting in minimization of emissions through the flare systems and/or discharged directly to the atmosphere as fugitive or stack emissions. FS-EMS will enhance the monitoring and reporting activities and mitigate the environmental impact of harmful Green House Gases (GHG) and other emissions like SOx, NOx, particulate matter, etc.

In the past, implementing an enterprise-wide emissions minimization plan was greatly hampered due to inadequate and/or faulty source-wise measurements of the emissions quantities. Known emissions measurement methods are difficult in their application, often expensive, and can be prone to failure. Further, in vast plant networks connected to many emissions sources, it was conventionally difficult to track and record data in real-time from the actual source to assign the causes of emissions. The analyzers and flow meters at the end of the pipe that record a facility’s total emissions are expensive to install, are maintenance intensive and do not reveal the actual sources in a complex plant.

The emissions monitoring system can assist in the reduction of hydrocarbon losses and accountability providing management the means to set realistic targets; to mitigate the environmental impact by reduction of SOx, NOx, and CO2 emissions; to provide the foundation for enterprise emission minimization initiatives, and provide data useful for hydrocarbon loss accounting programs and meet regulatory requirements at minimum cost.

FS-EMS leverages available automation technologies, namely distributed control systems and real-time data historians, to translate available real-time measurements of control valves (CV) openings for pressures, temperatures, and other process variables, in addition to manual input data and analyses to process them to determine quantities in mass or volume of emissions in real-time.
