Carbon bodies are heated in an oven (10) under low pressure and while being swept with an inert gas, gaseous effluent containing elemental or compound sodium in sublimed form being continuously extracted from the oven via an effluent exhaust pipe (44). At least one sodium--neutralizing agent is injected into the effluent exhaust pipe immediately downstream from the outlet for exhausting gaseous effluent from the oven. The sodium- neutralizing agent is selected from carbon dioxide and steam, and it can be injected continuously into the flow of gaseous effluent.
On chauffe les produits en carbone dans un four (10) sous pression réduite et sous balayage de gaz neutre, avec extraction continue hors du four d~effluent gazeux contenant du sodium élémentaire ou combiné sous forme sublimée, par une canalisation (44) d~évacuation d~effluent. Au moins un produit de neutralisation du sodium est injecté dans la canalisation d~évacuation d~effluent, immédiatement en aval de la sortie de l~effluent gazeux hors du four. Le produit de neutralisation du sodium est choisi parmi le dioxyde de carbone et la vapeur d~eau, et peut être injecté en continu dans le courant d~effluent gazeux.
