Abstract

TITRE DE L’INVENTION : DISPOSITIF DE DÉCOMPRESSION D’UN TRONÇON DE RÉSEAU DE GAZ Le dispositif (40) de décompression d’un tronçon (12) de réseau de gaz, par extraction du gaz présent dans ce tronçon, compression du gaz extrait et injection du gaz comprimé dans un contenant de gaz (13), par exemple un réseau de gaz ou un réservoir de gaz, comporte : - un surpresseur pneumatique (30) muni d’une chambre de détente (17) et d’une chambre de compression (23), - une première conduite de gaz (31) entre le tronçon de réseau et une entrée (18) de la chambre de détente, - une deuxième conduite de gaz (32) entre une sortie (19) de la chambre de détente et un compresseur de gaz (14) configuré pour injecter du gaz comprimé dans le contenant de gaz, - une troisième conduite de gaz (33) entre le tronçon de réseau et une entrée (15) de la chambre de compression et - une quatrième conduite de gaz (34) comprimé entre une sortie (16) de la chambre de compression et le contenant de gaz. Préférentiellement, le surpresseur pneumatique (30) comporte un piston libre (11) entre la chambre de détente (17) et la chambre de compression (23). Figure pour l'abrégé : figure 2TITLE OF THE INVENTION: DEVICE FOR DECOMPRESSING A SECTION OF GAS NETWORK The device (40) for decompression of a section (12) of gas network, by extraction of the gas present in this section, compression of the extracted gas and injection of the compressed gas into a gas container (13), for example a gas network or a gas tank, comprises: - a pneumatic booster (30) provided with an expansion chamber (17) and a compression (23), - a first gas pipe (31) between the network section and an inlet (18) of the expansion chamber, - a second gas pipe (32) between an outlet (19) of the expansion chamber expansion and a gas compressor (14) configured to inject compressed gas into the gas container, - a third gas line (33) between the network section and an inlet (15) of the compression chamber and - a fourth compressed gas line (34) between an outlet (16) of the compression chamber and the gas container. Preferably, the pneumatic booster (30) comprises a free piston (11) between the expansion chamber (17) and the compression chamber (23). Figure for the abstract: figure 2
