Product Overview<\/b><\/strong><\/h3>\n

NHD Desulfurization and Decarbonization Technology, internationally known as Seleoxl technology<\/strong>, is a high-efficiency gas purification process that uses polyethylene glycol dimethyl ether<\/strong>\u00a0as the absorption liquid. The process employs a physical absorption principle<\/strong>\u00a0for CO\u2082 removal and regenerates the solvent using air or nitrogen\u2014without consuming steam\u2014making it energy-efficient and environmentally friendly.<\/p>\n

This technology is included in the national key industry clean production technology catalog and is widely applied in petrochemical, coal chemical, and natural gas processing<\/strong>\u00a0industries. It effectively removes hydrogen sulfide (H\u2082S) and sulfur dioxide (SO\u2082) from gas streams, ensuring production safety and high gas purity.<\/p>\n

Working Principle<\/b><\/strong><\/h3>\n

The NHD process relies on physical absorption<\/strong>, where the sulfur-containing gas is introduced into a polyethylene glycol dimethyl ether absorption solution. The solvent selectively captures H\u2082S and COS<\/strong>\u00a0while allowing purified gas to exit at high purity.<\/p>\n

    \n
  • Solvent Regeneration<\/strong>: Achieved via air or nitrogen stripping, eliminating the need for steam and reducing energy consumption and operational costs.<\/li>\n
  • Safety & Compatibility<\/strong>: The solvent is low-volatility, non-corrosive, and environmentally benign, allowing the use of carbon steel equipment and simplifying system design.<\/li>\n<\/ul>\n

    Key Features<\/b><\/strong><\/h3>\n
      \n
