| abstract |
The invention concerns hollow fibre apparatus for the fractionation of fluids which comprises, n a mandrel towards the ends of which two sealing elements are situated which surround the said mandrel and by which the hollow fibres are held, the fibres extending from one sealing element to the other, at least one of these sealing elements being traversed by the hollow fibres so that open ends thereof are exposed at an outer side thereof and having an inner side opposite to the inner side of the other sealing element which is inclined at least in part with respect to the longitudinal axis of the mandrel, a casing which is arranged at least around the hollow fibres and the sealing elements and which defines, between its inner wall, the inner sides of the sealing elements and the mandrel, a chamber in which the hollow fibres are arranged, n first inlet and/or outlet means for introducing and/or withdrawing fluid which is circulated inside the hollow fibres, and second inlet and outlet means for introducing and withdrawing of fluid which is circulated outside the fibres inside the chamber. |
