Porogaramu y'ibicuruzwa

NHDni ubwoko bushya bw'umusemburo ukuraho sulfuri kandi ukuraho karubone, ufite ubuziranenge bwinshi, ubutabire bwiza n'ubushyuhe buhamye ku gice cy'ubushyuhe bwinshi, alkalite n'ubushyuhe. Ni byiza mu gutunganya gaze ikoze muri anthraco. Ishobora gukura sulfuri neza muri gaze ivanze ya aside ya gaze, gaze yo mu bishanga bya peteroli, gaze y'amakara mu nganda cyangwa mu mijyi ndetse na gaze ya peteroli ikoze mu mazi. By'umwihariko, ishobora gukura sulfuri neza.
