Title (EN) IMPROVED MOLECULAR SEAL
(FR) AMELIORATION A UN DISPOSITIF D"ETANCHEITE MOLECULAIRE
Abstract:
(EN) An improved molecular seal (10) for installation (14, 24) in a flare stack (23) system designed for burning of waste gases of lesser density than air, and for installation at an intermediate point in the flare stack, comprising a housing (11) of larger cross section than that of the flare stack (23), the housing being closed by plates (16, 20) at both ends with an outlet conduit (22) sealed through the plate at the outlet end of the housing, and connected to the flare stack (23). An inlet conduit (12) is sealed through the inlet end of the housing and is connected to the source of waste gases. Inside the housing the two conduits (26, 32) are deflected past each other so that they are substantially parallel, and have their axes in the same plane. The downstream end (28) of the inlet conduit (26) goes to a higher elevation inside the conduit than the upstream end (34) of the outlet conduit (32).
(FR) Un dispositif d"etancheite moleculaire ameliore (10) monte (14, 24) sur une souche d"un gazeificateur (23) concu pour bruler les gaz perdus de densite inferieure a celle de l"aire, a un point intermediaire de la souche du gazeificateur, comprend une enceinte (11) de section superieure a celle de la souche du gazeificateur (23), l"enceinte etant fermee par des plaques (16, 20) aux deux extremites et ayant un tuyau de sortie (22) fixe hermetiquement au travers de la plaque du cote sortie de l"enceinte et connecte a la cheminee du gazeificateur (23). Un tuyau d"entree (12) est fixe hermetiquement au travers de la plaque du cote entree de l"enceinte et il est connecte a la source des gaz perdus. A l"interieur de l"enceinte les deux tuyaux (26, 32) sont devies l"un par rapport a l"autre de sorte qu"ils restent paralleles et qu"ils aient leurs axes dans un meme plan. L"extremite en aval (28) du tuyau d"entree (26) s"eleve plus, a l"interieur de l"enceinte, que l"extremite en amont (34) du tuyau de sortie (32).
