Biological treatment of waste gas containing H2S and CS2 combined with production of concentrated NaOH and H2SO4



Biological treatment of waste gas containing H2S and CS2 combined with production of concentrated NaOH and H2SO4



Mededelingen Faculteit Landbouwkundige en Toegepaste Biologische Wetenschappen Universiteit Gent 63(4B): 1841-1847



In this study the results of a pilot experiment lasting over 6 months are presented in which a waste gas stream originating from a viscose rayon manufacturer and containing H2S and CS2 is treated biologically using the PURSPRING-system. Using the PURSPRING-system, removal of CS2 in combination with H2S is very well possible by converting it into sulphate. During the experiment removal of circa 90% H2S and circa 70% CS2 was achieved The pressure drop over the system was very low and did not exceed 150 Pa during 6 months of operation. In combination with an electrodialysis process, the produced SO42- can be used as a feed for the production of caustic soda and sulphuric acid. The caustic soda can be re-used for pH-control of the PUIRSPRING-PROCESS and the sulphasturic acid can be re-used by the viscose rayon manufacturer.
