Abstract: Disclosed is a multistage compressor having an anti-surge logic. The multistage compressor includes a main flow passage introducing an external gas and loading the external gas to a loading position; a first compressor, a second compressor, and a third compressor sequentially installed along the main flow passage; a first surge control valve, a second surge control valve, and a third surge control valve installed at outlet sides of the first compressor, the second compressor, and the third compressor, respectively; a first bypass flow passage, a second bypass flow passage, and a third bypass flow passage connected to the first surge control valve, the second surge control valve, and the third surge control valve, respectively; and a bypass gas mixing unit mixing the bypass gas introduced through the first bypass flow passage, the second bypass flow passage, and the third bypass flow passage, reducing the pressure of the bypass gas, and sending the bypass gas to an inlet side of the first compressor.
