Described herein is a column packing for a distillation apparatus, the column packing having an upper end opposite a lower end, the column packing comprising: a body extending along a central axis, the body comprising: a central channel extending parallel to the central axis, the central channel comprising a first open end opposite a second open end; and a plurality of perimeter channels circumscribing the central channel, each of the perimeter channels comprising a first open end opposite a second open end wherein the multi-channel body is formed of fluoropolymer.

Methods, systems, and techniques for desalinating a saltwater using a humidifier unit. The humidifier unit has a housing, which has a carrier gas inlet and a saltwater inlet. The humidifier unit also includes a packing, within the housing, having a surface with a critical surface tension of less than 25 mN/m according to the Zisman method. The packing is arranged to facilitate a saltwater that enters the housing through the saltwater inlet and a carrier gas that enters the housing through the carrier gas inlet to contact each other. The contact facilitates evaporation of the saltwater, which produces salt solids on at least a surface of the packing, a humidified gas and a concentrated brine.

A device and method for scrubbing an absorbate from a gas is described. The rotational absorber device comprises a housing having a gas inlet, a gas outlet, an absorbent liquid inlet and an absorbent liquid outlet; a rotor mounted for rotation in said housing and connecting to the inlets and outlets, the rotor comprising a plurality of scrubbing channels extending axially and parallel to a common rotation axis; and means for rotating the rotor. The device and method provide a scrubbing of the gas with improved selectivity and efficiency.
