While many sites use sodium sorbents for removal of HCl, and many others for removing SO2 or other acid gases, there is a paucity of publicly available data on the removal of HCl in the presence of SO2, especially in the case of coal-fired power generation. SOLVAir Solutions conducted controlled pilot tests using CAPP coal which demonstrates the selectivity of sodium sorbents to remove HCl in a medium to high sulfur environment.
LGR's N2O/CO Analyzer (Nitrous Oxide and Carbon Monoxide Analyzer) is the first instrument capable of continuously measuring ambient levels of nitrous oxide and carbon monoxide (with precision better than 0.1 ppb in 1 second) in real time (data rates to 10 Hz with optional external pump). Users can set up the instrument in minutes. Since CO is an excellent tracer of anthropogenic emissions, simultaneous measurements of CO and N2O can allow scientists to correlate the sources of N2O emissions.
