Abstract
Abstract In a centrifugal mass transfer device comprising a rotary, annular permeable element, annular plates are mounted adjacent the radially inner or outer face of the permeable element and gaseous or liquid material flowing from the permeable element across one surface of the annular plates is cooled or heated by a heat exchange fluid on the opposite surface of the plates. In this way condenser or vaporised material is returned to the permeable element.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
A centrifugal mass transfer device comprising a rotary permeable element formed as an annulus about its axis of rotation, characterised by having an annular plate which is thin in the direction of said axis, is made of a heat conductive material and is mounted adjacent the radially inner or radially outer face of said permeable element with one surface of said plate in communication with said adjacent face of said permeable element, and means to supply a heat transfer fluid to the other surface of said plate.
Claim 2
Dependent Claim
87 words
A centrifugal mass transfer device comprising a rotary permeable element formed as an annulus about its axis of rotation, characterised by having an annular plate which is thin in the direction of said axis, is made of a heat conductive material and is mounted adjacent the radially inner or radially outer face of said permeable element with one surface of said plate in communication with said adjacent face of said permeable element, and means to supply a heat transfer fluid to the other surface of said plate.
Claim 3
Dependent Claim
57 words
A device according to claim 1, characterised in that the annular plate is one of a plurality of plates, spaced apart in an axial direction, one surface of each plate being in communication with said adjacent face of said permeable element and having means to supply said heat transfer fluid to the other surface of each plate.
Claim 4
Dependent Claim
48 words
A device according to claim 2, characterised by having at least three plates, the space between a first and second plate being in communication with said permeable element and the space between said second and a third plate being in communication with said heat transfer fluid supply means.
Claim 5
Dependent Claim
40 words
A device according to claim 2 or claim 3, characterised in that said annular plates are substantially transverse to said axis of rotation, substantially parallel to each other and spaced apart by a distance between 0.25 mm and 5 mms.
Claim 6
Independent Claim
19 words
A device according to any preceding claims, characterised in that each plate is less than about 5 mms thick.
Claim 7
Independent Claim
14 words
A device according to any preceding claim, characterised in that each plate is contoured.
Claim 8
Dependent Claim
46 words
A distillation device characterised in that it comprises a mass transfer device as claimed in any preceding claim, means to supply a fluid material to said permeable element and means to remove a lighter product fraction and a heavier product fraction respectively from said permeable element.
