  • Corrosion inhibiting solutions and processes for refrigeration systems comprising halides of a group va metallic element
    Patent number: 6267908
    Abstract: Anticorrosion solutions useful for refrigeration processes are disclosed. Halides of Group Va metallic elements can be added to alkali metal halide absorption refrigeration solutions to minimize corrosion of the refrigeration system.
    Type: Grant
    Filed: January 5, 2000
    Date of Patent: July 31, 2001
    Assignee: FMC Corporation
    Inventors: Shyam Kumar Verma, Manuel Sarkis Mekhjian, George Robert Sandor, Philip John Boon
  • Corrosion inhibiting processes for refrigeration systems
    Patent number: 6083416
    Abstract: Organic compounds useful as anticorrosion agents in refrigeration systems. The organic compounds can be added directly into the refrigeration systems. Alternatively the organic compound can be added to an alkali metal halide absorption refrigeration solutions. The organic compounds can minimize corrosion of the refrigeration system.
