Flue Gas Analysis in Industry
Hydrogen sulfide (H2S) Hydrogen sulfide is a toxic and, even at very low concentrations (appr. 2,5 µg/m3), very odorous gas. Calibration gas, test gas Calibration gas is a gas of known concentration which is used to establish the response curve of an analyzer.

Removal of hydrogen sulfide
Hydrogen sulfide should be removed from the product gas while it is still hot so that the gas can be used directly without losing its heat. Sulfided solids were purged in nitrogen for about 30 min and then regenerated with a 6 % O2 and balance Calibration of gas chromatograph with h.

Determination of Hydrogen Sulfide Content
Hydrogen sulfide (H2S) is collected from a source in a series of midget impingers and absorbed in pH 3.0 cadmium sulfate (CdSO4) solution to form cadmium sulfide (CdS). Calculate the calibration factor, Y (wet test meter calibration volume divided by the dry gas meter volume, both volumes...
