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 condensed or vaporized material is returned to the permeable element.
