Polyethylene glycol dimethyl ether Use and Manufacturing
NHD (polyethylene glycol dimethyl ether) solvent is a new type of high-efficiency desulfurization and decarbonization solvent. The product has high purity and good chemical stability and thermal stability to high acidity, alkalinity media and high temperature. It is suitable for the purification of coal-made chemicalbook gas. It can effectively remove mixed acid gases such as natural gas, oil field gas, refinery gas and city gas, and hydrogen sulfide gas in liquefied gas. In particular, it can effectively remove organic sulfur.
