  • Patent number: 9034078
    Abstract: A method and apparatus are described for swing adsorption processes. The method includes obtaining different plates, wherein the plates have gaseous openings and a utility fluid opening. Then, the gaseous openings are substantially oriented along a common axis for gaseous openings and the plates are diffusion bonded. Once diffusion bonded, the gaseous openings within the module are wash coated with an adsorbent material.
    Type: Grant
