The LNG plant comprises a compression train (100) and a further compression train (200), and may advantageously implement for example 3-cycles pure-refrigerants liquefaction technologies or multiple-cycles pure-refrigerant and mixed-refrigerant liquefaction technologies. The compression train (100) comprises a first and a second set of axial compression stages (321, 322, 323), one main inlet (301), one main outlet (302), one auxiliary inlet (303) and/or one auxiliary outlet, wherein a fluid entering the compressor (130) through the auxiliary inlet (303) is redirected from a substantially radial direction to a substantially axial direction and/or a fluid exiting the compressor (130) through the auxiliary outlet is redirected from a substantially axial direction to a substantially radial direction. The further compression train (200) comprises a first set of impellers (411, 412) being centrifugal and unshrouded and a second set of impellers (421, 422, 423) being centrifugal and shrouded. |
