Abstract
A process and apparatus are disclosed for effecting mass transfer between two fluid phases, one of which is a liquid. The process comprises charging the fluids to an element which has a large interfacial area and which is permeable to the fluids and rotating the element such that the fluids are subjected to an acceleration of at least 300 m sec.sup.- 1 as they flow through the element.

A process for effecting mass transfer between two fluid phases, the first of which is a liquid, which process comprises the steps of:
- (a) charging the said fluids to an element which has an interfacial area of more than 1500 m.sup.-1, is permeable to the fluids and has pores which present a tortuous path to the fluids,
- (b) rotating the said element about an axis such that the fluids flow through the said pores with the first fluid flowing radially outwards away from the said axis, and
- (c) collecting at least a proportion of one of the fluids discharged from the said element.
Apparatus in which mass transfer between two fluid phases may be effected comprising a plurality of permeable elements each mounted in series along a common axis, said elements in series fluid flow communication one to the other and rotatable about the said common axis, means to charge the fluids to the series of permeable elements and means to discharge the fluids from the said series, ech of the said elements being permeable to the fluids and having an interfacial area of more than 1500 m.sup.-1 and pores which present a tortuous path to the fluids.
Distillation apparatus comprising a plurality of permeable elements, each with a fluid collecting means, mounted in series along a common axis, said elements in series fluid flow communication one to the other and rotatable about the said common axis, vapourising means to varporise a liquid the vapour of which may be charged to the series of permeable elements and liquifying means to liquify a vapour discharged from the said series, each of the said elements being permeable to the fluids and having an interfacial area of more than 1500 m.sup.-1 and pores which present a tortuous path to the fluids.
