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.

The power plant generates electric power to be provided to an electric grid, the plant including a gas turbine, a steam turbine and one or more electrolyzers that uses electric power to generate hydrogen starting from water; the hydrogen is temporarily stored inside the power plant in a small tank. When power plant energy production exceeds grid energy demand, the electrolyzer is connected to the grid so to usefully consume the electric power not desired by the grid operator at a certain time and generate hydrogen that is used by the gas turbine as a secondary fuel together with a primary fuel.

This liquid/gas separator for centrifugal motor compressor includes a sump internally equipped with at least one gas separator stage suitable to separate a gaseous phase from a liquid phase accepted in the sump entry. The sump internally includes a compartment in which the gaseous phase is separated by a separator stage, and in which is assembled by a compressor stage of the motor compressor.
