Abstract: L'invention concerne une colonne de réaction du type destiné à faire passer un composant liquide, dit solution, à traiter au contact d'un composant statique solide et divisé en grains tel que catalyseur, résine échangeuse d'ions, tamis moléculaire, ou autre. La colonne qui est essentiellement constituée d'une enceinte verticale comportant au moins deux orifices de passage de la solution, l'un à sa partie supérieure, l'autre à sa partie inférieure, est caractérisée principalement en ce que la pression régnant à la partie inférieure de la colonne est sensiblement égale à la hauteur de charge de la solution dans cette dernière de telle sorte que l'écoulement de la solution a travers le composant statique résulte principalement de sa gravité. En outre la partie inférieure de l'enceinte est d'une forme générale sensiblement conique, et le volume intérieur de cette partie conique est partiellement garni d'une masse de matériaux divisés inertes à l'égard de solution, ces matériaux étant disposés en couches horizontales constitués de particules de taille croissante de façon au moins discontinue depuis leur couche supérieure jusqu'à leur couche inférieure, tandis que les densités des particules sont au moins égales à celles du composant statique ou de la solution, la densité des particules des couches inférieures étant au moins égale à celle des couches supérieures. La forme et les proportions de cette colonne de même que les caractéristiques densimétriques et granulométriques de ses composants solides, autorisent une percolation régulière de la solution et un reclassement naturel des composants solides en situation de passage inversé.

Title: Air separation
Inventor: GLADMAN DAVID C F
IPC: F25J3/04
Filed: 1987-09-11
Granted: 1992-03-10
Abstract: ABSTRACT                    AIR SEPARATION   Air is fractionated in a double distillation column comprising lower pressure and higher pressure columns.  A condenser/reboiler provides reboiled oxygen to the bottom of the column.  Liquid nitrogen reflux is introduced into the  top of  the column.   Oxygen,  nitrogen and argon-en-riched streams are withdrawn from the column.  The argon-enriched  stream  is  separated  in  a  further distillation column and a product argon stream is withdrawn therefrom. A liquid stream comprising oxygen and nitrogen is with-drawn  from an  intermediate  level  of  the column,  is  at least  partially  reboiled  in  a  heat  exchanger,  and  is returned to the column at a level where the composition of the vapor  corresponds  approximately to  that  of the re-boiled liquid.  Heating for the heat exchanger is provided by a fluid stream withdrawn from the second distillation column. The fluid stream is returned to the second col-umn.   The  reboiling of the stream from the intermediate level  of  the  first  distillation  column  enhances  the efficiency of the air separation.

Granted: 1991-12-10
Abstract: Abstract A stair-like revetment structure is formed by using sloping blocks.   At the rear end of the block main body having an approximately rectangular and rearward sloping flat step are provided rear engagement pods opening like a wedge at the rear of  the  main  body  and  front  engagement  pods  having  an approximately same shape as the rear engagement pods via a concave portion at the center bottom of the front of the main body, the concave portion being provided between the front and the rear engagement pods, to thereby decrease cost by simplified structure.  Thus structured sloping blocks are arranged next to each other on a sloping foundation, and the front engagement pods of  the  sloping blocks  of  one  layer  is  inserted  into  the engagement concave portion between the rear engagement pods of the adjacent block to successively cover the sloping foundation in a zig-zag and step-wise fashion, to thereby form a water passage with the concave portion of the upper layer sloping blocks and the engagement concave portion formed between the rear engagement portion of the sloping blocks of one layer below.  The revetment structure can secure the safety of users since there are not exposed projections,  holes,  etc.  on the stair-like steps.
