Abstract
A method for characterizing refinery feedstocks according to their corrosivity is provided. The characterization is based on any of: dissociation of acids in the crude, breakup of naphthenic acid molecular associations, and/or dissociation of sulfur compounds in the feedstocks. In one embodiment, the characterization is done via vibrational spectroscopic measurements over a range of temperature, e.g., from ambient to 700° F. The method can be practiced in any of refinery, terminal, and laboratories. It can be used in conjunction with models and hardware to optimize the usage of refinery feedstocks in the blending and valuation of the feedstocks.
