Abstract
1,175,687. Diffusion apparatus. E. I. DU PONT DE NEMOURS & CO. 13 Dec., 1966 [22 Dec., 1965], No. 55708/66. Headings B1L and B1X. Diffusion apparatus 100 comprises cylindrical housing 101 within which are tightly packed a large number of hollow filamentary membranes 111 sleeved in a plurality of flexible porous members 112, all bundles being enclosed in flexbile porous sleeve 113. At each end, the filaments pass through cast wall member 950, which provides a fluid-tight end wall to the volume lying within housing 101 but external to the filaments. The internal face SF of the wall member is cylindrically concave. The filaments consist of a suitable polymeric material, polyethylene, terephthalate being preferred, and have a diameter of 10-500Á, with a uniform wall thickness of 1-100Á. Feed is passed to inlet 104, and effluent leaves through the corresponding outlet 104 at the far end of the housing. Permeate which passes through the filamentary walls is swept from the housing through outlet 108 by sweep fluid entering through inlet 109. Fig. 6 (not shown) illustrates a two-stage diffusion system suitable for use in obtaining oxygen-enriched air, or for separating hydrogen or methane from mixtures thereof with other gases, in the first stage of which a fraction of the feed is used for the sweep medium carrying the first stage permeate to the feed input of the second stage. The system embodies automatic control for keeping the overall composition of permeate and effluent constant.
