Title (EN) PROCESS FOR TREATING WATER CONTAINING HYDROCARBONS BY MEANS OF EXPANDED GRAPHITE.
(FR) PROCÉDÉ DE TRAITEMENT D'EAU CONTENANT DES D'HYDROCARBURES AU MOYEN DE GRAPHITE EXPANSÉ
Abstract: front page image
(EN) Process for the treatment of water containing low quantities of hydrocarbons (as dispersed or dissolved or emulsified) by means of expanded graphite having an apparent density from 2 to less than 5 g/l, wherein said hydrocarbons are present in a quantity less than or equal to 1 g/l, a specific surface area from 50 to 100 m2/g and a carbon/oxygen ratio (C:O) ≥ 100. The expanded graphite is mixed vigorously for a short time with the water contaminated by hydrocarbons and easily separated at the end of the treatment.
(FR) L'invention concerne un procédé de traitement d'eau contenant de faibles quantités d'hydrocarbures (par exemple, dispersés ou dissous ou émulsifiés) au moyen de graphite expansé ayant une masse volumique apparente comprise entre 2 et moins de 5 g/l, lesdits hydrocarbures étant présents en une quantité inférieure ou égale à 1 g/l, ayant une surface spécifique comprise entre 50 et 100 m 2/g et un rapport carbone/oxygène (C/O) ≥ 100. Le graphite expansé est mélangé vigoureusement pendant un court laps de temps avec l'eau contaminée par les hydrocarbures et est facilement séparé à la fin du traitement.
