ETIs Biogas to RNG Patended Solution Sli
SYSTEM BENEFITS

ETI's unique, patented biogas upgrading water wash system has the ability to provide superior gas treatment system benefits:

​Process achieves 98% methane content and with our CO2 polishing removal step achieve 99.7% methane content.


Modular low cost configurations providing up to 30%+ savings.


Minimize methane product process loss.


Gas contaminant removal of hydrogen sulfide (H2S), siloxanes, volatile organic compounds (VOCs) and Ammonia.


Produce "Renewable Natural Gas" (RNG) at lower cost than utility supplied natural gas. 


Carbon dioxide (CO2) by-product gas beneficial uses; pH adjustment,  phosphorous (struvite) control/removal, solids separation and others.


Water wash technology is well proven, has been the most common upgrading technology utilized world-wide.


Environmentally-friendly "Green" process.
