Symposium Primary Aluminum Industry - Energy and Emission Reductions: An LMD Symposium in Honor of Halvor Kvande
Presentation Title Sampling and analysis methodology review to report total PFC emissions
Author(s) Luis H. Espinoza-Nava, Julie Young
On-Site Speaker (Planned) Luis H. Espinoza-Nava
Abstract Scope Latest International Aluminum Institute (IAI) guideline includes various methodologies to measure total perfluorocarbon (PFC) emissions. Alcoa has continued to review those methodologies in selecting and implementing procedures that give reliable sampling and analytical techniques to measure high voltage, low voltage and pot starts PFC emissions from aluminum cell operation. Canister sampling offers the simplest, cost effective method to estimate total PFC emissions. However, it is important to investigate the sampling duration and frequency that can produce reproducible PFC emissions. Alcoa has tested the canister sampling procedures and compare GC-MS, FTIR and QCL-CF4 analytical techniques at two smelters to standardize the methodology with the goal to share the results and learnings within the aluminum industry.
