摘要:
2.1. Stoffaustauschpackung mit erhöhter Querverteilung und Quervermischung der Stoffströme bei gleichzeitiger Unterdrückung der Randgängigkeit. 2.2. Die Stoffaustauschpackung besteht aus einer Vielzahl von getrennten Strömungskanälen, die wechselweise gegen die Vertikale geneigt sind. Am seitlichen Rand der Packung sind die Kanäle geschlossen (4) und besitzen gleichzeitig Öffnungen (3), durch welche die Stoffströme in parallele Kanäle mit gegenläufiger Orientierung gelangen. 2.3. Die neuartige Packung wird über die Höhe verteilt mehrfach in konventionelle Stoffoder Wärmeaustauschkolonnen eingebaut.
摘要:
A system particularly useful for the cryogenic rectification of air to produce product, particularly high purity argon, comprising a structured packing arrangement having a defined moderate area density, a defined sharp corrugation angle and at least one of a defined short brick height and a defined packing structure modification.
摘要:
A structured packing is formed of packing elements. Each structured packing element comprises corrugated sheets and planar members alternating with and located between the corrugated sheets. Each pair of corrugated sheets 706 and 708 have corrugations 710 which are relatively steeply inclined at their ends. Thus, the angle of inclination of each corrugation 710 to the horizontal in middle portion 14 is less than in upper portion 712 and lower portion 716. Planar member 702 and 704 are positioned between sheets 706 and 708. The bottom horizontal edge 736 of member 704 is proximal the bottom horizontal edges of the sheets 706 and 708. The top horizontal edge 720 of member 702 is proximal the top horizontal edges of sheets 706 and 708.
摘要:
Improved capacity structured packing arranged in a section or brick wherein the packing section has a flat top and the packing in the base region of the section has a configuration making resistance to gas flow between the packing sheets in the base region less than resistance to gas flow between the sheets in the bulk region to increase capacity while retaining high mass transfer efficiency.
摘要:
Improved capacity structured packing arranged in a section or brick wherein the packing in the base region (L) of the section is configured differently from the structured packing in the bulk region (U) making resistance to gas flow between the packing sheets in the base region (L) less than resistance to gas flow between the sheets in the bulk region (U).

Cette colonne (2), du type à garnissage ondulé-croisé, comporte des moyens de renvoi de liquide au voisinage des bords du garnissage et des moyens (29A) de distribution du liquide et du gaz, qui contribuent à diminuer substantiellement la hauteur de la colonne. Application aux installations de séparation des gaz de l'air.
