Spiral-wound adsorber module

A spiral-wound adsorber apparatus comprising:

• a) a layer of adsorbent having a thickness and extending along a longitudinal axis and wrapped in a spiral about said longitudinal axis:
• b) an inlet screen and an outlet screen on opposite sides of said layer of adsorbent for retaining said adsorbent in said spiral and for supplying and withdrawing a fluid from opposite sides of said adsorbent bed through said inlet screen and said outlet screen;
• c) at least one impermeable wall wrapped between said inlet and outlet screen defining an inlet channel between an impermeable wall and said inlet screen to distribute fluid to said inlet screen and defining an outlet channel between an impermeable wall and said outlet screen to collect fluid from said outlet screen;
• d) an inlet conduit in fluid communication with said inlet channel for supplying fluid to said inlet channel;
• e) an outlet conduit in fluid communication with said outlet channel for withdrawing fluid from said outlet channel;
• and,
• f) means at opposite transverse ends of said layer of adsorbent for retaining said adsorbent and structurally supporting said inlet and outlet screens.
