Gas measurement of the converter to determine catalyst activity or predict if there a leaks in the equipment is a useful technique to optimise plant performance and reduce SO₂ emissions. This paper details gas measurement techniques to determine the current activity of each bed in the catalytic reactor, by which the optimum process conditions. NZ: Air handling quipment used in the transport or extraction of polluted air, corrosive gases or dust., US: These fans are used in a wide range of stationary air pollution control applications, including selective catalytic reduction, wet scrubbing, thermal oxidizers and in baghouses. Sulfur Dioxide (SO 2) is one of a group of gases called sulfur oxides (SO x).The other gases in the group are much less common in the atmosphere.   Pilot scale experiments have demonstrated a method of reducing the amounts of oxides of nitrogen (NOx) emitted by industrial boilers and powerplant combustors that involves (1) injection of H2O2 into flue gases and (2) treatment of the flue gases by caustic wet scrubbing like that commonly used to remove SO2 from combustion flue gases.

NGCC Pollutant Control Technology (lb/MWh-gross) SO2 Low sulfur content fuel NOx Dry low NOx burners and SCR PM (Filterable) N/A N/A Hg N/A N/A HCl N/A N/A The NGCC cases were designed to achieve approximately ppmvd NOx emissions (referenced to 15 percent O2) through the use of a dry low NOx (DLN) burner in the CTG – the DLN. The saturated steam generated in the waste heat boiler and in the process gas cooler The condensation of sulfuric acid is sensitive in respect to too low cooling air tem- is separated from the boiler water in steam drum and routed to the 2nd interbed cooler perature; hence a small part of the cooling air can be recycled to the inlet of the.
