Abstract
Apparatus for separating fluid mixtures includes plural tubular membranes parallel to each other. Each of the membranes has an inner lumen and the flow direction is from the exterior of the membrane to the inner lumen. Each tube is surrounded by a larger diameter feed tube and a gap is formed between the outside service of the tubular membrane and the inside service of the feed tube. This annulus provides a feed flow channel for the fluid mixture along the outer surface of the tubular membrane. The annulus has first and second ends connected to entrance and discharge ports respectively of the feed flow. The inner lumen of the tubular membranes are sealed from the annular gap and provided with a connection for the discharge of the permeate flow.
