Isicelo seMveliso

I-NHDsisinyibilikisi esitsha esisebenza kakuhle kakhulu sokususa i-sulfurizing kunye ne-de-carbonating esinobunyulu obuphezulu, ikhemistri egqwesileyo kunye nozinzo lobushushu kwiindawo ezine-asidi ephezulu, i-alkality kunye nobushushu. Sifanelekile ukucocwa kwegesi eyenziwe nge-anthraco. Singayisusa ngempumelelo i-hydrogen evulcanized kwi-mixed acid gas yegesi yendalo, igesi ye-oyile, igesi yamalahle kwimizi-mveliso okanye kwizixeko kunye negesi ye-petroleum enyibilikisiweyo. Ngokukodwa, singasusa i-organic sulphur ngempumelelo.
