A charge gas compression train for ethylene including a first compressor including a first group of compression stages, a second group of compression stages, and a third group of compression stages. The first group of compression stages includes an outlet configured to be connected to a first intercooler inlet. The second group of compression stages includes a second compressor inlet configured to be connected to a first intercooler outlet, and a second compressor outlet configured to be connected to a second intercooler inlet. The third group of compression stages includes a third compressor inlet configured to be connected to a second intercooler outlet. The first, the second, and the third group of compression stages are integrated in a first common casing and operate at the same rotation speed. The first compressor includes a plurality of unshrouded and shrouded impellers, where an unshrouded impeller is positioned upstream to a shrouded impeller.

Charge gas compression train for ethylene

Method and system for compressing a fluid in a gas phase and for pumping the fluid in a dense phase. The system includes a compressor part having an impeller; a compressor part inlet that receives the fluid in the gas phase; a compressor part outlet that provides the fluid in the gas phase; a temperature changing device that changes a phase of the fluid; a pump part having an impeller; a pump part inlet that receives the fluid in the dense phase from the compressor part outlet; a pump part outlet that outputs the fluid in the dense phase from the system; a single bull gear configured to rotate around an axial axis with a predetermined speed; plural pinions contacting the single gear bull and configured to rotate with predetermined speeds, and a pump shaft configured to rotate the at least one impeller of the pump part.

Single system with integrated compressor and pump and method

Heat exchanger device for a gas seal () for centrifugal compressors equipped with a fluid heat exchanger () positioned between the gas seal () and the housing wall of the seal to keep the temperature of the seal () low in the case of high temperatures of the wall and/or compressed gas.
