Enhanced NRU for High N2 Rejection - Field Proven

 Provides a system and method that applies novel algorithms and compositions for efficiently adjusting compression, unit turn down, pressure and flows of a pressure swing adsorption unit. The present design also reduces overall horsepower, increases unit's product gas recovery, maximizes product gas quality and allows for non-disturbance of upstream and downstream equipment in regard to pressure and flow oscillations. Raw gas streams addressed include methane (CH4), nitrogen (N2), oxygen (O2), carbon dioxide (CO2), water (H2O), Hydrogen Sulfide (H2S) and non-methane organic compounds (NMOC) gases/vapors. The design incorporates a CO2 and H2O trim units and provides a VPSA N2 and O2 rejection section.
