- Hydrodynamics and mass transfer of textile vibrating-valve trays
- Published at:Chemical Engineering Research and Design. Vol. 77, no. A7, pp. 627-32. Oct. 1999
New types of vibrating valve 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 column efficiency, volumetric mass transfer coefficient and pressure drop per theoretical tray were measured and compared. The high mass transfer rate, low investment and operating costs, corrosion and heat resistance make the vibrating valve trays attractive for gas absorption and air cleaning in environmental protection.
