Title
(EN) METHOD AND APPARATUS UTILIZING HYDROCARBON POLLUTANTS
(FR) PROCEDE ET APPAREIL UTILISANT DES AGENTS POLLUANTS D'HYDROCARBURE
Abstract
(EN)
An environmentally safe apparatus (10) for reclaiming uncondensed hydrocarbons normally exausted to the atmosphere from the still column (14) of a glycol dehydrator system (12), and utilizing the uncondensed hydrocarbons as fuel in the burner (20) of a reboiler fire-tube (19) by natural draft of the fire-tube exhaust stack (23).
(FR)
L'invention concerne un appareil (10) écolophile de récupération d'hydrocarbures non condensés dégagés normalement dans l'atmosphère depuis la colonne (14) de distillation d'un système déshydrateur (12) au glycol, et utilisant les hydrocarbures non condensés comme combustible dans le brûleur (20) d'un tube de fumée (19) de rebouilleur par tirage naturel de la cheminée (23) d'échappement du tube de fumée.
