NHD ni ubwoko bushya bwo gukora cyane-de-sulfurizasi na de-karubone yumuti hamwe nubuziranenge bwinshi, chimie nziza & ubushyuhe butajegajega kubitangazamakuru bya acide nyinshi, alkalite nubushyuhe. Irakwiriye kwezwa gaze ya anthraco-synthique. Irashobora gukuraho neza hydrogène y’ibirunga ivuye muri gaze ya aside ivanze ya gaze gasanzwe, gaze yo mu mavuta, gaze yamakara mu nganda cyangwa mumijyi na gaze ya peteroli. By'umwihariko, irashobora de-sulfurize sulfuru kama neza.
