| Abstract: | Stainless steel packings were treated by liquid chemical method and the performances of corrosion resistance and wettability as well as mass transfer efficiency of metal structured and dumped packings were further tested before and after treatment. It was shown that the treatment was quite effective to improve the ability of anti-corrosion and mass transfer efficiency of stainless steel packings. After surface treatment, the HETP of tested packings decreased about 20% and 30% in average for common organic system and high surface tension system such as aqueous solution respectively. |
