Definitions

  • compact motor-compressors may often attempt to achieve the higher compression ratios by increasing the number of compression stages within the single, hermetically sealed housing. Increasing the number of compression stages, however, increases the overall number of components (e.g., impellers and/or other intricate parts) required to achieve the desired compressor throughput (e.g., mass flow) and pressure rise to achieve the higher compression ratios. Increasing the number of components required in these compact motor-compressors may often increase length requirements for the rotary shaft and/or increase distance requirements between rotary shaft bearings. The imposition of these requirements often results in larger, less compact motor-compressor arrangements as compared to previous compact motor-compressors utilizing fewer compression stages.

    la compression du fluide de traitement via le premier compresseur à un étage (140) et le deuxième compresseur à un étage (150) pour fournir un fluide de traitement comprimé contenant de la chaleur à partir de la compression de celui-ci et ayant un rapport de pression d'environ 10:1 ou plus ;
    la direction du fluide de traitement comprimé vers un système de récupération de chaleur (160) ;
    l'absorption d'au moins une partie de la chaleur contenue dans le fluide de traitement comprimé dans le système de récupération de chaleur (160) ; et la compression du fluide de traitement via le premier compresseur à un étage (140) pour fournir un premier fluide de traitement comprimé ayant un rapport de pression d'au moins environ 3,8:1.
  9. Le procédé selon la revendication 8, comprenant en outre l'alimentation du premier compresseur à un étage (140) en fluide de traitement à partir d'une source externe.
  10. Le procédé selon la revendication 8, comprenant en outre :
    la direction du premier fluide de traitement comprimé à partir du premier compresseur à un étage (140) vers le deuxième compresseur à un étage (150) via de la tuyauterie (130) ; et
    la compression du premier fluide de traitement comprimé via le deuxième compresseur à un étage (150) pour fournir le fluide de traitement comprimé ayant un rapport de pression d'environ 10:1 ou plus.
  11. Le procédé selon la revendication 8, dans lequel le premier compresseur à un étage (140) et le deuxième compresseur à un étage (150) sont suspendus au-dessus au niveau des extrémités opposées de l'arbre d'entraînement (108) dans une configuration à double extrémité.
  12. Le procédé selon la revendication 8, dans lequel le premier compresseur à un étage (140) et le deuxième compresseur à un étage (150) sont des compresseurs centrifuges à entrée axiale.
  13. Le procédé selon la revendication 8, dans lequel chacun des premier compresseur à un étage (140) et deuxième compresseur à un étage (150) comprend :
    une entrée axiale (142, 152) configurée pour recevoir le fluide de traitement ;
    un arbre rotatif (114, 116) couplé ou intégré à l'arbre d'entraînement (108) ;
    un impulseur couplé à l'arbre rotatif (114, 116) et positionné en aval de l'entrée axiale (142, 152) ;
    une aube d'entrée couplée de manière mobile à l'entrée axiale (142, 152) et configurée pour guider le fluide de traitement vers l'impulseur ;
    un diffuseur positionné en aval de l'impulseur et configuré pour recevoir le fluide de traitement à partir de l'impulseur ; et
    une volute de décharge positionnée en aval du diffuseur et configurée pour collecter le fluide de traitement à partir du diffuseur et décharger le fluide de traitement via une sortie (144, 154).
