Aplikasyon pou pwodwi

NHD se yon nouvo kalite segondè-efikas de-sulfurizing ak de-carbonatation sòlvan ak pite segondè, ekselan chimi & estabilite chalè nan medya ki gen asidite segondè, alkalite ak tanperati. Li apwopriye pou pirifye gaz anthraco-sentetik. Li ka efektivman de-sulfurize idwojèn vulkanize a soti nan melanj gaz asid gaz natirèl, gaz lwil oliv, gaz chabon nan faktori oswa vil ak gaz likid petwòl. An patikilye, li ka de-sulfurize souf òganik efektivman.
