Abstract
A arranged in the casing and configured to rotate around a vertical rotation axis. The rotor comprises at least one impeller having an impeller suction side and an impeller delivery side. The compressor includes a gas inlet and a gas outlet, as well as a gas flow path extending from the gas inlet to the gas outlet. An inlet plenum extends from the gas inlet towards the impeller suction side. At least one suction tube having a lower suction end and an upper discharge end is arranged such that the lower suction end thereof is arranged at a bottom of the inlet plenum. The suction tube extends upwardly towards the impeller suction side.

A centrifugal compressor, comprising:
- a casing comprising a gas inlet and a gas outlet;
- a rotor arranged in the casing and configured to rotate around a vertical rotation axis, said rotor comprising at least one impeller having an impeller suction side and an impeller delivery side;
- a gas flow path extending from the gas inlet to the gas outlet;
- and,
- in the casing, an inlet plenum extending from the gas inlet towards the impeller suction side;
- wherein least one suction tube having a lower suction end and an upper discharge end;
- wherein the lower suction end is arranged at a bottom of the inlet ple-num;
- and wherein, the suction tube extends upwardly towards the impeller suction side.
A method for removing liquid from a liquid-tolerant centrifugal compressor comprising:
- a casing having a gas inlet and a gas outlet;
- a rotor arranged in the casing for rotation around a vertical rotation axis, said rotor comprising at least one impeller having an impeller suction side and an impeller delivery side;
- a gas flow path extending from the gas inlet to the gas outlet;
- an inlet plenum arranged in the casing and extending from the gas inlet towards the impeller suction side;
- the method comprising the following steps:
- collecting liquid in the inlet plenum of the compressor;
- and,
- aspirating liquid from the inlet plenum through at least one suction tube having a lower suction end at a bottom of the inlet plenum and extending upwardly from the suction end to a discharge end towards the impeller suction side.
