Polyethyleneglycol dimethyl ether has stable chemical properties, good thermal stability, small volatilization loss, high boiling point, low freezing point, low vapor pressure and many other advantages. It is an excellent organic solvent with excellent selective absorption and removal function for CO2 and H2S. It is suitable for the purification of coal-based synthesis gas and the removal of acidic gases in natural gas, oilfield gas, refinery gas and city gas. In recent years, it has been widely used in gas purification processes.
