The invention relates to a device for purifying fluids, comprising a mass transfer apparatus that contains a more volatile fluid and a less volatile fluid. The mass transfer apparatus contains a structured packing having a first packing unit (10) and a second packing unit (100). The first packing unit (10) and the second packing unit (100) have a wave-like profile, wherein open channels (12, 14, 16, 112, 114, 116) are formed by the wave-like profile. The channels (12, 14, 16) of the first packing unit (10) intersect with the channels (112, 114, 116) of the second packing unit, wherein the channels (12, 14, 16, 112, 114, 116) can be traversed by the less volatile fluid so that the channel can be wetted by the less volatile fluid, whereby a film of the less volatile fluid forms on the surface of the channel so that either the more volatile fluid or the less volatile fluid can be purified by means of a mass transfer between the more volatile fluid and the less volatile fluid. The first packing unit (10) is in physical contact with the second packing unit (100) via spacer elements (24, 34, 44, 134, 144). |
