ABSTRACT:
A method and apparatus for determining the presence of heavy hydrocarbons (including those from unprocessed crude oil) in distillate streams and/or reformer feed includes taking at least one sample, spectrally analyzing the at least one sample for at least one heavy hydrocarbon component, determining the concentration of the analyzed hydrocarbon component using the spectrally determined concentration in an appropriate mathematical model, and determining the total heavy hydrocarbon concentration from the determined values for each sample.
