The analysis of the water gas so far given enumerates the chief constituents, but in reality there are traces of other products, such as carbon bisulphide, carbonyl sulphide, and thiophene, derived from the sulphur in the uel, which, minute in quantity, may nevertheless in the certain chemical processes produce appreciable and un-iesirable results from the iron contained in the fuel, ninute amounts of iron carbonyl are formed, which in nost processes in which water gas is used is a matter jf no importance, but if the gas is to be used for ighting with incandescent mantles, its removal is de-.irable. 

The carbonyl sulphide is evolved at 20° C. together with hydrocyanic acid, formic acid and carbon disulphide. The gas is purified by passing through concentrated aqueous caustic potash to absorb the acid vapours, and the carbon disulphide is absorbed in a mixture of triethylphosphine, pyridine and nitrobenzene. After drying with sulphuric acid, the gas may be further purified by liquefaction or absorption in toluene.3... 

Byman (1977) detected volatile sulphur species in the headspace gas over sulphides oxidising in vitro. The major gases detected were, initially, carbonyl sulphide and carbon disulphide. As the experiments continued dimethyl sulphide, (CH,)2S was detected, presumably as the result of bacterial action.

Sulfinol process A regenerative process used to remove or reduce the level of hydrogen sulphide, carbon dioxide, carbonyl sulphide, and other organic sulphur compounds such as mercaptans from natural gas. It involves gas absorption with solvents in which the gas is contacted countercurrently in an absorption column with the solvent The scrubbing process uses di-isopropanolamine dissolved in a mixture of sulfolane (C H SO ) and water. Regenerated solvent is introduced at the top of the absorber The solvent in which...
