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.

Seal leak gas recovery system using an ejector and method

A compressor arrangement having a main compressor, a piping system containing process gas to be extracted after the shut-down of the main compressor and one or more components emitting or leaking depressurized process gas while the compressor is operating or starting up; the compressor arrangement further comprises one or more collectors arranged to collect the depressurized process gas emitted from said components and an additional compressor fluidly coupled with the piping system and with the collectors in in order to compress the depressurized process gas coming from the components while the compressor is starting up or operating and to compress process gas coming from the piping system after a shut-down of the compressor.
