About the Solution:

The Guild Associates approach is to use the Molecular Gate advantage in a single step process. The process flow is simple: They compress the gas to 100 psig, remove the bulk of the moisture using a cooling process, reheating the resulting gas with waste heat from the compressor, remove moisture, CO2, siloxanes, H2S and VOCs in a Molecular Gate Pressure Swing Adsorption system and deliver the resulting product gas to the local grid at 90 psig.

This simple-to-operate technology has been installed at wastewater treatment plants and commercial digesters. The technology offers the benefits of:

  • Single step removal of impurities
  • All media is regenerated – no need for replacement
  • H2S completely removed from any level up to 11,000 PPM
  • Siloxanes removed to non-detect levels
  • Dehydration to CNG requirements without a separate dryer required
  • No chillers required
  • Dry system operation, with no waste product other than condensed water from compression
  • Operation and maintenance is much simpler with Automatic start-up and shutdown at a push of a button and automatic product purity control without operator attention

  • This is Biogas Upgrading Made Easy!
