  • Method and apparatus for wet desulfurization spray towers
    Patent number: 9468885
    Abstract: A method and apparatus or system is provided for cleaning a flue gas and/or cooling a flue gas with a dispersed finely divided absorption liquid. As such, the absorption liquid is dispersed in a wet scrubber through which flue gas flows for absorption liquid and flue gas intermingling and contact to produce a cleaned flue gas. The absorption liquid supplied to the wet scrubber is dispersed from upwardly spraying anti-clogging nozzles and downwardly spraying nozzles arranged to maximize absorption liquid and flue gas contact with minimal spray interference between nozzles.
    Type: Grant
    Filed: May 9, 2016
    Date of Patent: October 18, 2016
    Assignee: General Electric Technology GmbH
