The invention relates to a process for treating naphthenic acid containing whole crudes or fraction thereof to reduce or eliminate their acidity by contacting the acidic whole crude or fractions thereof at a suitable temperature typically of less than 200 °C with a neutralizing amount typically from 0.25:1 up to 10:1 of overbased detergent. The process has the additional benefits of reducing materials handling problems associated with emulsion formation in treated crudes.
L'invention porte sur un procédé de traitement de bruts entiers ou de fractions de ceux-ci contenant de l'acide naphténique, visant à réduire ou à éliminer leur acidité par mise en contact du brut acide ou de fractions de celui-ci, à une température adéquate, généralement de moins de 200 DEG C, avec un détergent superbasique en dose neutralisante, à raison de 0,25:1 à 10:1. Le procédé présente l'avantage supplémentaire de réduire les problèmes de la manipulation des matières liés à la formation d'émulsions dans les bruts traités.
