Fluid separation apparatus

摘要: A hollow fiber membrane-type fluid separation apparatus useful for selective of fluids in various techniques such as gas permeation, liquid dialysis, ultrafiltration, reverse osmosis, etc., which comprises at least one pair unit structures are arranged uniaxially series within a cylindrical pressure vessel, said comprising assemblies having permeability, means collecting permeated fluid, is held between side tube sheets provided each terminal the and capable passes through sheet, permeation pipe taking out penetrates perpendicularly center, fitting with passageway passing concentrated being not permeated, around central region so to surround pipe.
