Application:

NHD is a new type high-effective de-sulfurizing and de-carbonating solvent with high purity, excellent chemistry & heat stability to media of high acidity, alkality and temperature. It is suitable for purification of anthraco-synthetic gas. It can effectively de-sulfurize the vulcanized hydrogen out of mixture acid gas of natural gas, oil-field gas, coal gas in factories or cities and liquefied petroleum gas. In particular, it can de-sulfurize organic sulphur effectively.
