Description:
Summary/Accomplishments (Outputs/Outcomes):
- PolarisTM membranes, which selectively remove CO2, H2S and siloxanes from CH4.
- PegasusTM membranes, which selectively remove CO2, N2 and O2 from CH4.
Conclusions:
MTR has been developing two membranes (PolarisTM and PegasusTM) that selectively permeate carbon dioxide and retain methane. In this project, commercial-scale membranes and modules were produced, which showed separation properties meeting the project target performance, with good stability over the time period tested. The project demonstrated the technical and economic feasibility of using these two membranes for various applications in landfill gas and biogas purification. Both PolarisTM and PegasusTM membranes are at early commercialization stages, and the MTR sales group has begun marketing the membrane products and processes for various applications involving dilute methane recovery.
