摘要： The reciprocating compressor comprises a compressor frame, a crankshaft and a connecting rod, connecting the crankshaft to a crosshead. A piston rod connects a piston to the crosshead. The piston reciprocates in a gas compression cylinder. At least one pressure-drop module is positioned between the gas compression cylinder and a crosspiece guide. The piston rod extends from the gas compression cylinder through a pressure-drop chamber of the pressure-drop module. Also disclosed herein is a method of operating a reciprocating compressor.

摘要： The integrally geared compressor comprises a bull gear supported for rotation in a gear casing, and a plurality of pinion shafts supported for rotation in the gear casing. Each pinion shaft comprises a respective pinion, which meshes with the bull gear. A first pinion shaft has a first end drivingly coupled to an axial compressor unit comprising a gas inlet, a gas outlet and an axial compression wheel. A second pinion shaft is drivingly coupled to a centrifugal compressor arrangement.

摘要： A multi-stage turboexpander and a method for generating mechanical power therewith are disclosed. The multi-stage turboexpander includes a casing and a shaft, arranged for rotation in the casing. The shaft is supported by a first bearing at a first shaft end portion and a second bearing at a second shaft end portion. A first radial impeller and a second radial impeller are arranged between the first bearing and the second bearing on the shaft for co-rotation therewith around a rotation axis.
