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.

A hydrogen cooled pressure packer, systems, and methods of operation are provided. The pressure packer can include a flange portion and a plurality of packing cups coupled to the flange portion. One or more packing cups of the plurality of packing cups include at least one injection channel extending therethrough and terminating in at least one injection port. The pressure packer can also include a seal abutted with at least one packing cup of the plurality of packing cups. The pressure packer can be configured for use in a hydrogen compressor operable within a hydrogen vehicle refueling facility.

It is disclosed a method for reducing the pulsation level in a multi-compressor plant where each compressor of a plurality of compressors is driven by a respective motor. The method manages to reduce the pulsation level by starting a first motor of a first compressor and then starting in succession each one of the other motors in a way to synchronize all motors between each other with a specified phase shift.
