Packings Sulzer metal gauze packing

Efficiency and pressure drop data for Sulzer BX metal gauze structured packing and for three test mixtures are shown in Fig. 14-75. For the ethyl benzene/styrene test mixture, the effect of operating pressure is shown. The liigh viscosity mixture, propylene glycoFetnylene... 

The hydraulic operation of structured packings with countercurrent gas and liquid flows is somewhat different than that of random dumped packings. The wire-gauze type is wetted by capillary action, so that the entire geometric surface area becomes available for mass transfer at low liquid flow rates. Thus, Sulzer BX packing was found to have 2 A times the static liquid holdup of Flexipac 2 or Gempak 2A sheet metal types of structured packings [14]. However, once the surface is completely wetted, capillary action has only a small effect as the liquid rate increases. 

Hiflow rings, structured Sulzer gauze packings (type BX), as well as type X sheet metal packings and Montz packings X with flow channels of a = 30° resulted in a higher flooding point constant Cfi,o. compared to Eq. (2-64), namely ...
