【Abstract】 The experimental study of simultaneous heat and mass transfer perform-ance of hydrophilised polyprophlene packings has been made in a column of 105 mmdiameter with the air-hot water system.After the polypropylene packings was hydro-philised by chemical treatment in liquid phase,the results show that the mass trans-fer coefficients k_H·a of that packings can be increased about 25%.更多还原
