  • Selective catalytic reduction (SCR) reactor assembly to remove fine particles from poisoning or interfering with SCR catalyst activity in biomass fuel applications
    Patent number: 8603401
    Abstract: The present invention relates to a selective catalytic reduction (SCR) reactor assembly for removing fine particles that interfere with SCR catalyst activity in biomass fuel applications. The selective catalytic reduction (SCR) reactor assembly includes at least one turning vane disposed in a plenum chamber of the reactor, at least one rectifier layer disposed downstream of the at least one turning vane, and at least one active catalyst layer for removing particulate matter. The turning vane is adapted to impart a directional turn to the flue gas flowing through the reactor, and the at least one rectifier ensures even flow distribution.

  • In-line localized monitoring of catalyst activity in selective catalytic NOx reduction systems
    Publication number: 20050255605
    Abstract: Localized catalyst activity in an SCR unit for controlling emissions from a boiler, power plant, or any facility that generates NOx-containing flue gases is monitored by one or more modules that operate on-line without disrupting the normal operation of the facility. Each module is positioned over a designated lateral area of one of the catalyst beds in the SCR unit, and supplies ammonia, urea, or other suitable reductant to the catalyst in the designated area at a rate that produces an excess of the reductant over NOx on a molar basis through the designated area. Sampling probes upstream and downstream of the designated area draw samples of the gas stream for NOx analysis, and the catalyst activity is determined from the difference in NOx levels between the two probes.
