SEAL LEAK GAS RECOVERY SYSTEM USING AN EJECTOR AND METHOD

The system comprises a rotary turbomachine (3), including dry gas seals (9). A seal leak gas collecting line (14) fluidly connects the at dry gas seals (9) to the seal leak gas inlet (15) of the ejector (13). A seal leak gas discharging line (23) fluidly couples the dry gas seals (9) with a seal lea...

Zusammenfassung:	The system comprises a rotary turbomachine (3), including dry gas seals (9). A seal leak gas collecting line (14) fluidly connects the at dry gas seals (9) to the seal leak gas inlet (15) of the ejector (13). A seal leak gas discharging line (23) fluidly couples the dry gas seals (9) with a seal leak gas discharge (25) at a discharge pressure, lower than the seal leak gas pressure. A leak discharge control valve (27) along the seal leak gas discharging line (23) is adapted to divert at least part of the seal leak gas in the seal leak gas discharging line (23). Also, a method for recovering seal gas leaking from a dry gas seal arrangement is disclosed.
