Raschig 双语例句1. According to the experimental results, there was no obvious strong relationship between packing specific surface area and mass transfer coefficient. As to materials, ceramic packings had superior mass transfer efficiency. And probably because the shape of Raschig rings and saddle type might hinder liquid distribution, the mass transfer efficiency of spherical packings was higher than those of Raschig rings and saddle type. Besides, the kLa values for hydrophilic packings were generally higher by about 11%~43% than those of hydrophobic packings. Moreover, the mass transfer of wire mesh was better than that of blades and steel rings.
