Hydrodynamic and Mass Transfer Performance of Bilayer Fixed Valve Tray

Abstract:

Fixed valve trays have the advantages of low pressure drop, high efficiency, anti-fouling, simple structure, low manufacture cost and long runtime and therefore have been widely used abroad. This paper presents a new bilayer fixed valve (BFV) tray which has some improvements on traditional fixed valve trays. The hydrodynamic and mass transfer performance of BFV tray, sieve tray and F1 valve tray was experimentally studied with air-water-oxygen system in a 1.2m column. The results showed that the BFV tray possesses low pressure drop, high capacity, wide operating range and high efficiency.
