Title (EN) COMPRESSOR SYSTEM EQUIPPED FOR FUGITIVE GAS HANDLING AND FUGITIVE GAS SYSTEM OPERATING METHOD
(FR) SYSTÈME DE COMPRESSEUR ÉQUIPÉ D'UNE MANIPULATION DE GAZ FUGITIF ET PROCÉDÉ DE FONCTIONNEMENT D'UN SYSTÈME DE GAZ FUGITIF
Abstract:
(EN) A compressor system (10) includes a gas compressor (18) with dry gas seals (66, 68) about a driveshaft (64). The compressor system (10) also includes a fugitive gas system (30) having a gas conduit (36) in fluid communication with a collection cavity (34, 35) in a collector (32) coupled to the gas compressor (18) to receive fugitive gas leaked through a pressurized gas leakage path (67, 69). The fugitive gas system (30) may be structured for flaring the gas, and includes a pressure control system (42) with an accumulator tank (44), and a vent line (46) for venting gas pressure and having a backpressure regulator (52) therein. Fugitive combustible gas is conveyed through a flow restriction orifice (96, 100) downstream of the compressor (18).
(FR) L'invention concerne un système de compresseur (10) qui comprend un compresseur de gaz (18) avec des joints à gaz sec (66, 68) autour d'un arbre d'entraînement (64). Le système de compresseur (10) comprend également un système de gaz fugitif (30) ayant un conduit de gaz (36) en communication fluidique avec une cavité de collecte (34, 35) dans un collecteur (32) couplé au compresseur de gaz (18) pour recevoir un gaz fugitif ayant fui à travers un trajet de fuite de gaz sous pression (67, 69). Le système de gaz fugitif (30) peut être structuré pour évaser le gaz, et comprend un système de commande de pression (42) comportant un réservoir d'accumulateur (44), et une ligne d'évent (46) pour évacuer la pression de gaz et ayant un régulateur de contre-pression (52) à l'intérieur de celle-ci. Le gaz combustible fugitif est transporté à travers un orifice de restriction d'écoulement (96, 100) en aval du compresseur (18).
