Abstract:The hydrodynamic and mass transfer performances of Super Mini Ring (SMR) are studied in the TDBY 300 packing tower with air NH 3 H 2O system. The geometric characteristics and the curve of △P/Z,H 0 to F V, H OG ,K Ga and HETP to G are obtained.The result shows that the packing has the advantage of great flux,moderate pressure drop,uniform gas liquid distribution and excellent mass transfer performances.The results are of value in the engineering design
Key words:SMR packing; hydrodynamic; mass transfer; performance
