New Application note on Oxygenate Trace analysis in C2-C5 hydrocarbons

New Application Note on Oxygenate Trace analysis in C2-C5 Hydrocarbons Streams Hydrocarbon mixtures may contain trace amounts of oxygenates, such as alcohols and ethers, which could poison the catalyst during processing. To determine these compounds at trace levels, the standardized method ASTM D7423 is used. As this method suffers from discrimination of high boiling compounds such as Propanol,...
