PROCEDEU DE PURIFICARE A AERULUI POLUAT CU GAZE SULFUROASE |
摘要 |
<p>This invention relates to a method for purifying waste air from sulphuric gases, in particular from hydrogen sulphide, carbon disulphide and sulphur dioxide by adsorption and oxidation in a bath containing inorganic oxidizing compounds soluble in water, e.g. hypochlorites of alkali metals, preferably sodium hypochlorite in an amount equivalent to at least 0.1 g, preferably 3-5 g of available chlorine per 1 liter of bath and, if need be additions in the form of chemisorbents such as polyethylene glycol or aliphatic amines in an amount of at least 0.005 g/l of bath, and/or oxidation catalysts such as vanadium and/or palladium salts in an amount of at least 0.01 g/l of bath, and/or organic oxidizing compounds soluble in water such as hydroquinone in an amount of at least 0.1 g/l of bath, with a pH-value of 9-12, in a closed cycle of bath.</p> |
