The DryOxo integrated deoxo and temperature swing adsorption (TSA) dryer package is an efficient and scalable solution for getting you one step closer to capturing the RNG opportunity.
DryOxo (integrated deoxo dryer)
Your single source solution with guaranteed component compatibility
Purifying biogas from oxygen is a critical step in upgrading raw biogas to Renewable Natural Gas (RNG). The DryOxo integrated package consists of our leading ZerO2TM oxygen removal (deoxo) technology combined with a TSA dryer to remove excess water vapor typically before Nitrogen removal and/or compression to sales.
The DryOxo skid provides RNG project operators with an effective and environmentally safe solution for eliminating both oxygen and moisture from biogas streams, including dairy, swine as well as Landfill Gas (LFG) operations.
