- HYDRODYNAMICS AND MASS TRANSFER OF TEXTILE VIBRATING-VALVE TRAYS
- Published at:Trans IChemE, Vol 77, Part A, October 1999
New types of vibrating-va lve trays with textile valves were investigated to determine their optimal construction. Hydrodynamic and mass transfer measurements were carried out in a pilot plant with different vibrating-valve and conventional valve trays under identical experimental conditions. The total tray pressure drop (Dp), column ef ciency (g), volumetric mass transfer coef cient (KGa) and pressure drop per theoretical tray (Dp/Nth) were measured and compared.
The high mass transfer rate, the low investment and operating costs, the corrosion and heat
resistance make the vibrating-va lve trays attractive for gas absorption and air cleaning in
