A hollow fiber membrane gas separation apparatus of a compact design suitable for separation and purification of gases is disclosed. The apparatus comprises an outer housing that consists of a detachable bowl and a head closure, and a removable hollow fiber membrane cartridge positioned therein. The cartridge contains a concentric tubular inner core member and is surrounded by a shell and at least one end closure. The cartridge is attached by its first axial end in a sealed and removable manner to a gas flow conduit positioned coaxially in the housing closure wherein the conduit is in fluid communication with a gas inlet or product gas outlet port formed in the housing head closure and by its second axial end to a waste gas exit port in the bowl. The feed gas inlet port and the product gas outlet port in the head closure are spaced in a straight line for a short overall distance providing for a linear connection with other components of a gas separation system, which is a preferred system component packaging.

Hollow fiber membrane gas separation cartridge and gas purification assembly

An integral hollow fiber membrane gas purification apparatus is disclosed. The apparatus comprises one or more filtration elements and a hollow fiber membrane cartridge placed coaxially in a common housing. In some embodiments, the filtration elements are omitted and the hollow fiber membrane cartridge is employed as a combined gas separation/filtration device. The apparatus of this invention is particularly useful for conditioning compressed air that includes the removal of both suspended matter and water vapor.

Integral hollow fiber membrane gas dryer and filtration device

A hollow fiber membrane gas separation apparatus of a compact design suitable for separation and purification of gases is disclosed. The apparatus comprises an outer housing that consists of a detachable bowl and a head closure, and a removable hollow fiber membrane cartridge positioned therein. The cartridge contains several concentric separation zones and provides for efficient countercurrent flow configuration between the feed gas on the shell side and the permeate sweep gas on the lumen side of the hollow fiber membranes.
