The compression train (13) for a dehydrogenation plant (1) comprises a driver (36) and a single centrifugal compressor (35) drivingly coupled to the driver. The centrifugal compressor comprises a single casing and a plurality of compressor sections (39.1, 39.2, 39.3) inside said casing (37). Each compressor section comprises at least one impeller (40.1, 40.2) arranged for rotation in the casing (37). The compressor (35) is adapted to compress a mixture containing propane, propylene and hydrogen, having a molecular weight between 20 and 35 g/mol, from a suction pressure between about 0.2 barA and about 1.5 barA to a delivery pressure between about 11 barA and about 20 barA, with a volumetric flowrate comprised between about 120,000 m3/h and about 950,000 m3/h. 用于脱氢设备(1)的压缩系(13)包括驱动器(36)和驱动地联接到驱动器的单个离心式压缩机(35)。离心式压缩机包括单个壳体和壳体(37)内的多个压缩机区段(39.1,39.2,39.3)。每个压缩机区段包括被布置用于在壳体(37)中旋转的至少一个叶轮(40.1,40.2)。压缩机(35)适于将包含丙烷、丙烯和氢的混合物从在约0.2barA和约1.5barA之间的抽吸压力压缩至在约11barA和约20barA之间的递送压力，该混合物具有在20g/mol和35g/mol之间的分子量，具有在约120,000
