Image Number 13 for United States Patent #4214990.

A hollow-fiber permeability apparatus includes:a housing; a bundle of permeable-wall hollow fibers disposed in the housing; inlet means for supplying a first fluid into the spaces between the fibers; outlet means for withdrawing the first fluid from the housing, the first fluid being led through at least one of the inlet and outlet means in a lamelliform flow toward the bundle, whereby the first fluid can uniformly flow through the whole bundle; and means for flowing a second fluid inside the fibers such that materials selectively permeate through the walls of the fibers.
