The Molecular Gate® Technology for CO2 Removal and Nitrogen Rejection

Molecular Gate™ Technology

Molecular Gate System to Remove CO2 and Reject Nitrogen
  • Based on proprietary adsorbents developed for size selective and other difficult separations
  • PSA process cycles are designed to maximize the yield of the product methane
  • Focused on Nitrogen and/or CO2 Removal from natural gas, from Coal beds/Coal Mines, Biogas, landfill gas, etc…
  • Offered as packaged systems by Guild Associates through an exclusive licensing of the technology by Engelhard Corporation
  • Two Dozen projects underway
