Meterial for equipment treating exhaust gas containing SO2.

Low Cost Coal-based Carbons for Combined So2 and No Removal from Exhaust Gas

Treating Ventilation Exhaust Air for Odor Control

and Implications Odor control for swine facilities has focussed on storage and the land application phases of manure handling. A third component, ventilation exhaust air, has received little attention. This research was targeted at reducing odor emitted from ventilation exhaust air by filtering odor carrying dust particles. The ultimate objective is to develop a system that could be implemented...

Zeolite screening for the separation of gas mixtures containing SO2, CO2 and CO.

We used a combination of experiments and molecular simulations to investigate at the molecular level the effects of zeolite structure on the adsorption and diffusion of sulfur dioxide, carbon dioxide and carbon monoxide as well as separation processes of their mixtures. Our study involved different zeolite topologies and revealed numerous structure-property trends depending on the temperature a...

Quantum cascade laser sensor for SO2 and SO3 for application to combustor exhaust streams.

We have demonstrated a high-sensitivity, room-temperature quantum-cascade (QC) laser sensor for detection of SO2 and SO3 under conditions relevant to aircraft test combustor exhaust. Two QC lasers probe infrared absorption features at 7.50 and 7.16 microm for SO2 and SO3, respectively, with a common dual-beam detection system. We inferred a noise-equivalent absorbance of approximately 1 x 10(-4...

Fluorescent probe for biological gas SO2 derivatives bisulfite and sulfite.

A coumarin-hemicyanine dye was reported for ratiometric fluorescent detection of SO2 derivatives HSO3(-) and SO3(2-) based on a novel addition-rearrangement cascade reaction.
