  • Method and system for detecting moisture in a process gas involving cross interference
    Patent number: 9194797
    Abstract: A system includes a moisture analyzer configured to detect moisture in a process gas. The moisture analyzer includes an absorption cell that encloses and conducts the process gas. The moisture analyzer also includes a pressure control device that may reduce a pressure of the process gas inside the absorption cell. The moisture analyzer includes a light emitting device that may transmit light through the process gas inside the absorption cell, as well as a photodetector that may detect an intensity of the light transmitted through the process gas and exiting the absorption cell.
    Type: Grant
    Filed: December 20, 2013
    Date of Patent: November 24, 2015
    Assignee: General Electric Company
    Inventors: Xiaoyong Frank Liu, Yufeng Huang, Gary S. Parece, Anthony Kowal, Chong Tao

  • Method and system for detecting moisture in natural gas
    Patent number: 8547554
    Abstract: A system includes a moisture analyzer configured to detect moisture in natural gas. The moisture analyzer includes an absorption cell that encloses and conducts the natural gas. The moisture analyzer also includes a pressure control device that may reduce a pressure of the natural gas inside the absorption cell. The moisture analyzer includes a light emitting device that may transmit light through the natural gas inside the absorption cell, as well as a photodetector that may detect an intensity of the light transmitted through the natural gas and exiting the absorption cell.
