PROCESSES FOR PREPARATION OF ARN ACIDS AND DERIVATIVES THEREOF AND THEIR USES

A process for the preparation of at least one ARN acid or salt thereof comprising: (I) allowing at least one ARN acid salt to form during the production of crude oil in the presence of water; (II) removing at least 5 wt% of the formed at least one ARN acid salt, e.g. from the oil water interface; an...

Beschreibung
Zusammenfassung:	A process for the preparation of at least one ARN acid or salt thereof comprising: (I) allowing at least one ARN acid salt to form during the production of crude oil in the presence of water; (II) removing at least 5 wt% of the formed at least one ARN acid salt, e.g. from the oil water interface; and optionally (III) converting said salt into an acid. L'invention porte sur un procédé pour la préparation d'au moins un acide ARN ou sel de celui-ci, ce procédé comprenant les opérations consistant à : (I) amener au moins un sel d'acide ARN à se former pendant la production d'huile brute en présence d'eau ; (II) éliminer au moins 5 % en poids du ou des sels d'acide ARN formés, par exemple à partir de l'interface huile-eau ; et facultativement (III) convertir ledit sel en un acide.
