NHDNdi mtundu watsopano woyeretsera wothandiza kwambiri wochotsa sulfuri ndi de-carbonated solvent wokhala ndi chiyero chapamwamba, chemistry yabwino kwambiri komanso kukhazikika kwa kutentha kwa mpweya wokhala ndi asidi wambiri, alkality ndi kutentha. Ndi woyenera kuyeretsa mpweya wopangidwa ndi anthraco. Imatha kuchotsa sulfuri bwino mu mpweya wosakaniza wa asidi wa gasi wachilengedwe, gasi wamafuta, gasi wamalasha m'mafakitale kapena m'mizinda komanso gasi wamafuta osungunuka. Makamaka, imatha kuchotsa sulfuri wachilengedwe bwino.
