Abstract
Tube units useful for a variety of application are provided. Preferably, individual laminated tubes are joined to each other by intermediate pieces to produce a wide ribbon of parallel tubes. The tubes are porous to certain substances, allowing them to serve as an apparatus to exchange material between two or more fluid streams. The tubes are particularly useful as membrane modules for exchange of material between two fluids. Continuous and discontinuous methods for constructing such tube units are also taught.
