<p>Apparatus for effecting mass transfer between two fluid phases the first of which is a liquid, which apparatus comprises (a) an element (9) which is permeable to the fluids, which has pores which present a tortuous path to the fluids, and which is rotatable about an axis such that the fluids, are subjected to a mean acceleration of at least 300 m sec<-><2> as they flow through the pores with the first fluid flowing radially outwards away from the said axis, (b) means for charging the fluids to the permeable element and (c) at least means for discharging one of the fluids or a derivative thereof from the permeable element, characterised in that the permeable element comprises strands, fibres, fibrils or filaments or mixtures thereof. The apparatus may be used in absorption, distillation or extraction processes.</p> |
