Abstract
Naphthenic acid corrosivity of hydrocarbon feedstocks is correlated with the chemical composition of naphthenic acids, and especially with a ratio between an alpha fraction and a beta fraction of naphthenic acids. Contemplated plants, configurations, and methods are directed to reducing naphthenic acid corrosivity of hydrocarbon feedstocks by increasing the beta fraction over the alpha fraction.
