The present invention is a process for decreasing the acidity of a starting acidic crude oil by contacting an acidic crude with an effective excess of ammonia dissolved in said crude to form an ammonia-continuous oil discontinuous phase at a temperature and conditions sufficient to form the corresponding amide of the naphthenic acids. The process is useful in the processing of acidic crudes.
La présente invention concerne un procédé de réduction de l'acidité d'un pétrole brut acide de départ par mise en contact d'un pétrole brut acide avec un excès effectif d'ammoniac dissous dans ce pétrole brut afin de former une phase discontinue ammoniac-pétrole obtenu en continu à une température et dans des conditions suffisantes pour produire l'amide correspondant aux acides naphténiques. Le procédé s'utilise dans le traitement du pétrole brut acide.
