摘要： A reaction chamber enables a reaction between received elemental mercury gas and an oxidizing agent gas. The reaction chamber includes a porous (or permeable) medium through which to pass the elemental mercury gas and the oxidizing agent gas. Passing of the elemental mercury gas and the oxidizing agent gas through the porous medium supports a number of useful functions. For example, the porous medium enhances mixing of the elemental mercury gas with the oxidizing agent gas to enhance a reaction. Also, the porous medium increases an amount of surface area in a reaction chamber on which reactions (e.g., heterogeneous surface reactions) can take place between the elemental mercury gas and the oxidizing agent gas to form oxidized mercury gas. Accordingly, the reaction chamber configured to include a porous medium enhances a conversion of elemental mercury gas into oxidized mercury gas.

摘要： A calibration assembly generates elemental mercury and oxidized mercury for calibrating components of a mercury monitoring system, including making necessary adjustments to efficiencies of a mercury compound converter and an elemental mercury detector. The calibrator generates an elemental mercury sample having a known elemental mercury concentration, [Hg0]1 and combines an oxidizing component with the elemental mercury sample, thereby producing a reduced concentration of elemental mercury [Hg0]2 within the sample. The calibrator measures the concentration of elemental mercury [Hg0]2 within the sample and calculates a difference between the known elemental mercury concentration, [Hg0]1 and the reduced concentration [Hg0]2. The difference between [Hg0]1 and [Hg0]2 is substantially equal to the concentration of oxidized mercury produced by the calibrator. The concentration of oxidized mercury can also be calculated as the difference between elemental mercury detected after passing a sample stream containing oxidized mercury through a channel which includes the converter and the reduced concentration [Hg0]2 detected after passing the sample stream through a channel which bypasses the converter. By providing oxidized mercury at calculated concentrations, the calibrator allows a user to calibrate continuous emission monitoring systems for accurate response to both elemental mercury and oxidized mercury.

摘要： An oxidized mercury converter utilizes a combination of heat, reduced pressure, and dilution when converting oxidized mercury in a gas sample into elemental mercury. The converter applies heat to a gas sample to thermally convert oxidized mercury within a gas sample into elemental mercury and an oxidizing component, and thereafter reduces the pressure of the gas sample to minimize combination of the elemental mercury with other oxidizing compounds present in the gas sample and/or with byproducts of the thermal conversion (e.g., the oxidizing components). The converter thus allows an accurate analysis of the total amount of mercury, both oxidized and elemental forms, present within a gas sample without the need to use consumable reagents in the mercury conversion process.

摘要： An improved elemental mercury analyzer utilizes a fluorescence assembly in combination with a fluorescence quenching reduction mechanism to detect the concentration of elemental mercury within an emission gas sample, via fluorescence of the mercury within the gas sample, while minimizing fluorescence quenching of the gas sample. In one arrangement, the analyzer contains the emission gas sample under a vacuum or negative pressure while detecting fluorescence of the elemental mercury within the emission gas sample. By performing fluorescence detection of the emission gas sample at reduced pressure relative to the pressure of the as-sampled emission gas, the analyzer reduces the number of particle collisions within the emission gas sample over a certain period of time. Such collisional deactivation, and/or the addition of oxygen depleted gas such as nitrogen to the gas sample, reduces fluorescence quenching of the emission gas sample, improving accuracy of detection of mercury.
