Abstract:
The concentration of H
2S and CS
2 in the industrial waste gases of CS
2 is very high.The TF-C treatment technique consists of two steps:the absorption of H
2S in waste gases by TF dusulfurizerand the adsorption of CS
2 in waste gases by the activated-carbon. The technique has been applied inchemical factory and reached good results,e.g. ,the removal efficiency of H
2S and CS
2 in waste gasesare 99.9%and 79%,respectively.The treated waste gases can be safely emitted in accordance withthe standard GBJ4-73.The by-products of CS
2 and S during the process are also recovered.
