Abstract:
A method for effecting mass transfer between at least two flowing media using a device having a plurality of discs which are vertically spaced relative to one another so as to form fluid passageways therebetween and wherein the discs have generally planar upper surfaces and are rotatable about a center vertical axis of a housing of the device and wherein a medium distribution means is mounted so as to convey a first medium toward the fluid passageways between the spaced discs, the method comprising the steps of:introducing the first medium through the distribution means as the plurality of discs are rotated so as to convey the first medium onto the upper surfaces of the rotating discs to thereby create a plurality of parallel boundary layer flows, introducing a second medium in the form of a gas into said housing so as to flow outwardly relative to the central axis of the housing past the distribution means and into said fluid passageways defined between the plurality of discs to thereby effect a mass transfer between the first and second mediums moving through the fluid passageways defined between the spaced discs, and collecting the first medium as the first medium is discharged from the upper surfaces of the rotating discs.
