Predictive Emission Monitoring (PEM) combined with Data Acquisition Systems (DAS) represents a novel and cost-effective approach for compliance monitoring of source emissions. PEM Systems are software-based and do not need gas analyzers. Interfaced with plant control systems, PEMS utilize process inputs to offer continuous, real-time monitoring of pollutants. PEMS are built with quality assured emissions test data along with parallel process data and can be certified according to U.S. EPA 40 CFR or European regulations. Together with DAS, PEMS provide self-sufficient compliance solutions. Applications exist for utilities, petrochemical, chemical, steel, other industrial plants or municipal sites. PEMS are suitable for all gas- and oil-fired emission sources in lieu of Continuous Emission Monitoring Systems (CEMS), featuring equal accuracy and data quality.
PEMS offer significant cost benefits with lower CAPEX and much lower OPEX cost than CEMS. PEMS and DAS require for operation very little or no plant manpower.
The technology already gained significant interest in the GCC region due to their obvious advantages for compliance monitoring. Consequently, many FEED studies, tenders and projects in GCC qualify PEMS as core component for Air Emission Monitoring Systems (AEMS) to determine criteria pollutants like NOx, SO2 and CO above a certain mass emission value for all applicable sources. Pollutants with low emissions can be calculated and estimated with so-called Simplified PEMS (SPEMS) like Continuous Parameter Monitoring Systems (CPMS) or utilizing emission factors and stoichiometric calculations. SPEMS are the typical emissions monitoring tool for flares.
This paper details the design of Air Emission Monitoring Systems with PEMS as main compliance monitoring component. Features, benefits and peculiarities of such AEMS will be highlighted.
