Patent number: 7824628Abstract: A method and apparatus for the decontamination of fluid ammonia are described. Liquid or gaseous ammonia is purified of contaminants by passage through an adsorbent bed, the contaminants accumulating in the bed. A portion of the purified ammonia discharged from the bed is decomposed to hydrogen and nitrogen. The hydrogen is used to regenerate an adsorbent bed which has accumulated sufficient contaminants to reduce its ability to further decontaminate incoming ammonia satisfactorily. Preferably there are a plurality of interconnected adsorbent beds, with some being operated for ammonia decontamination while others are being regenerated, with their operations being reversed as needed to maintain a continual production of decontaminated ammonia from the plurality of beds. Computers or other controllers can be used to control such bed operations and interchanges. Internal production of hydrogen makes the system self-contained and no addition of hydrogen is needed.Type: GrantFiled: May 7, 2002Date of Patent: November 2, 2010Assignee: Entegris, Inc.Inventors: Daniel Alvarez, Jr., Jeffrey J.
