Improving Measurement for Smokestack Emissions

Through measurement science, enable the owners of stationary sources (primarily the electric power industry) and their regulatory agencies (federal and state) to better characterize greenhouse gas (GHG) emissions.  The intended result is to create sound scientific data that can be used to determine if local and global emission targets are being met.  This workshop brought together diverse stakeholders to share perspectives, discuss strengths and weakness of current CO₂ flux measurement protocols, and introduced new methods that reduce uncertainty and clearly tie emissions measurements to national standards.

Workshop Topics

• Calibration and uncertainty of pitot probes used in relative accuracy test audits (RATAs)
• Innovative flow measuring techniques applicable for smokestacks
• CO₂ emission traceability for stationary sources
• Advanced multipath ultrasonic meters for improved flow measurement
• Concentration and flow rate measurement uncertainty for continuous emissions monitoring systems (CEMS) and RATA testing
• Fuel calculation method for determining CO₂ exhaust for natural gas or coal
• Challenges of accurately measuring smokestack CO₂ emissions
