Abstract
The system comprises a rotary turbomachine, including dry gas seals. A seal leak gas collecting line fluidly connects the at dry gas seals to the seal leak gas inlet of the ejector. A seal leak gas discharging line fluidly couples the dry gas seals with a seal leak gas discharge at a discharge pressure, lower than the seal leak gas pressure. A leak discharge control valve along the seal leak gas discharging line is adapted to divert at least part of the seal leak gas in the seal leak gas discharging line. Also, a method for recovering seal gas leaking from a dry gas seal arrangement is disclosed.
