Abstract
A new method was used to modify the film forming of plastic structure packing and the comprehensive performance with commercial packing was compared in the same conditions .In order to evaluate the hydrodynamics and mass transfer performance of the commercial and modified structured packing with textured surface , the experiment of oxygen desorption from water was carried out in a packed column of φ190 mm under the condition of liquid spray density 10-36 m3/(m2· h) and F factor 0.2-3(m/s)· (kg/m3)0.5.The result shows that with liquid spray density of 10, 24, 36 m3/(m2 · h), the height of liquid transfer unit HoL of surface modified structured packing is decreased by 29.50%,23.00% and 23.95% respectively in comparison with those of a commercial packing, while the pressure drop is lower by 85.37%, 89.71% and 88.35% than commercial packing respectively , which demonstrates a significant improvement in mass transfer performance for the surface modified packing.In addition, the correlations of HoL and pressure drop were obtained , flooding phenomenon was discussed by narrow channel theory and the foundation of industrial design was built .关键词
