Abstract Experim ents w ere perform ed on the hydraulic and liquid side m ass transferperform ance ofpackings in a Pyrex glass colum n of500m m internaldiam eter w ith apacking height of1.00m forallpacking types. The colum n w as operated in counter current w ith w ater air oxygen system . The liquid side m ass transfer characteristicsw as tested by stripping oxygen from a saturated w ater into air by m eans of the N T U H T U m ethod. The packing tested w as a type 250 Y. The experim entalresultsshow thatthe separative efficiency ofcom plexed m eshed sheetstructured packing isobviously higher than other structured packings in the sm allratio of liquid to gas. In com parison w ith the w ide use Mellapac packing the efficiency of the com plexedm eshed sheetstructured packing is high than 30% .
