A tail gas exhausting pressure stabilization control system is provided. The system can control the pressure and the flow rate of a gas and a driving gas inputted therein, such that when the gas and the driving gas are mixed and outputted to a tail gas exhausting outlet, the pressure thereof can be controlled under a predetermined pressure. Besides, when the back pressure is generated because of the exhausted gases from the outlet, an energy-saving module can adjust the pressure of the driving gas outputted to an eductor in accordance with the detecting result of the back pressure in order to resist the back pressure. Thus, the exhausted gases from the outlet can be still under the predetermined pressure between the gas and a gas distribution component so as to stabilize the pressure and flow rate of the exhausted gases from the outlet and save the driving gas.

A compressor arrangement for an internal combustion engine, including a compressor which is located in a compressor housing and has a low pressure side and a high pressure side, and includes a vacuum supply device which has: a propellant channel which has a nozzle and is fluidically connected on one side via a propellant inlet connection to the high pressure side of the compressor and on the other side via a propellant outlet connection to the low pressure side of the compressor; and a vacuum channel opening into the propellant channel fluidically between the propellant inlet connection and the propellant outlet connection.

A silencer is equipped with a hollow tubular portion in which a discharge flow passage is formed that communicates on one end side thereof with a discharge port of a fluid pressure device (ejector) through which a pressure fluid is discharged, a cap member attached to another end part of the tubular portion, a sound absorbing member attached to an inner wall surface of the tubular portion, and a plurality of discharge ports adapted to discharge the pressure fluid, which has passed through the discharge flow passage in an axial direction of the tubular portion, in radial directions perpendicular to the axial direction.

An industrial ejector includes: a Laval nozzle in which a first channel which has a throat and along which a fluid flows in a first direction is formed; and a main body which is formed in a tubular shape, in which the Laval nozzle disposed therein is fixed to a part of an inner surface thereof, and in which a second channel is formed between the rest of the inner surface and the Laval nozzle. The second channel is disposed at a first side with respect to the first channel in a second direction perpendicular to the first direction. An opening is obliquely cut and formed in an end of the first channel at a downstream side and inclined toward the first side in the downstream direction and then toward the second channel.

A gas-oil separation plant (GOSP) is configured to process crude oil produced from a well. A production stream from the well operates at a first pressure. A processed crude oil stream from the GOSP flows to a multi-phase ejector. The multi-phase ejector induces flow of a production stream from the well in response to the flow of the processed crude oil stream.
