Abstract:
Oil derived from plastic waste typically exceeds the feedstock specifications of steam crackers in terms of Si, Na, Fe, and other metal content. This session discusses how ICP-OES, the technique of choice for monitoring these elements, can best overcome the challenges presented by a highly organic matrix such as pyoil. The high organic load necessitates a robust plasma system to avoid carbon buildup. To access the most sensitive emission lines, spectral interferences stemming from the carbon-rich matrix need to be separated reliably from the signal. Strategies for a significantly reduced Argon consumption will also be presented.
