  • Dynamic seals In generic methods for compressing a gaseous medium and in generic reciprocating compressors, as used for example in the compression of natural gas or hydrogen, resulting in wear after about 500,000 cycles on the dynamic seals. These unavoidable signs of wear result in a reduction in performance and can possibly lead to failure of the reciprocating compressor. Dynamic seals must therefore be regularly replaced with a relatively large amount of effort.

Abstract

L'invention concerne un procédé pour comprimer une substance gazeuse, en particulier de l'hydrogène, au moyen d'un compresseur à piston dont le piston comprend une/des garniture(s) d'étanchéité dynamique(s). Selon l'invention, une substance contenant du graphite est introduite dans la/les chambre(s) de cylindre, pendant et/ou après le processus de compression, ladite substance étant conçue pour se déposer sur la/les garniture(s) d'étanchéité dynamique(s). Cette invention concerne en outre un compresseur à piston comprenant une ou plusieurs chambres de cylindre, le(s) piston(s) comprenant des garnitures d'étanchéité dynamiques. Selon l'invention, des moyens sont prévus pour introduire une substance contenant du graphite dans la ou les chambres de cylindre.
