Abstract:
[Problem] To provide a filler which is a porous body and which can reduce filling height to a practical level, and a distillation-separation method and distillation-separation apparatus using the filler. [Solution] At least a surface of a filler filled in a distillation column to which a treatment liquid is supplied is covered by a means for forming fine pores constituted from a porous substance that exhibits capillarity, and the means for forming fine pores is a sprayed metal layer or a metal sintered compact. The sprayed metal layer can be a sprayed aluminum layer. An example of a filler obtained using a sprayed aluminum layer is "Matsui Specification 250S sprayed aluminum".
