Title (EN) APPARATUS AND METHOD OF DECONTAMINATING HYDROCARBONS CONTAINING PCB
(FR) APPAREIL ET METHODE DE DECONTAMINATION D'HYDROCARBURES CONTENANT DU PCB
Abstract:
(EN) Apparatus mounted on a mobile vehicle (10) is utilized to process hydrocarbons having high toxicity due to the presence of PCB. Hydrocarbons containing PCB are blended with metallic sodium at a temperature of about 130oC and thereafter the mixture is separated into its components one of which is a hydrocarbon containing less than about 2 ppm of PCB. The water is removed from the hydrocarbons by filter (20) and directed to a reactor (22, 24). The hydrocarbons are brought up to temperature by cycling the hydrocarbon the heat exchanger (30) and the reactor. The metallic sodium is then added by flowing the heated hydrocarbon through chemical ejector (34). The reactant sodium chloride and phenyl polymer are separated from the hydrocarbon by separator (40).
(FR) Appareil monté sur un véhicule mobile (10) et utilisé pour transformer des hydrocarbures présentant une haute toxicité en raison de la présence de PCB. Les hydrocarbures contenant du PCB sont mélangés à du sodium métallique à une température d'environ 130oC, le mélange étant ensuite séparé de manière à isoler ses composants, dont l'un est un hydrocarbure contenant moins de deux parties par million environ de PCB. L'eau est retirée des hydrocarbures par un filtre (20) et dirigée vers un réacteur (22, 24). Les hydrocarbures sont portés à la température voulue par mouvements cycliques de l'hydrocarbure entre le thermoéchangeur (30) et le réacteur. Le sodium métallique est ensuite ajouté en faisant couler l'hydrocarbure chauffé le long d'un éjecteur chimique. Le chlorure de sodium et le polymère phénylique réactifs sont séparés de l'hydrocarbure par un séparateur (40).
