Technical Feasibility
This technology combines existing process technologies—cryogenic and adsorption separation—making it relatively easy to integrate into existing natural gas processing facilities or biogas refinement plants. The patent claims specify connection methods for each facility and concrete gas recirculation configurations, suggesting potential for implementation through partial modifications utilizing existing piping and control systems. The ability to use general-purpose rubber as a CO2 adsorbent reduces risks associated with specialized material procurement, lowering adoption barriers.
Success Scenario
Implementing this technology could enable licensees' natural gas processing plants or biogas refinement facilities to consistently supply high-purity methane at significantly lower energy costs than current methods. This is estimated to enhance profitability from methane sales while strengthening compliance with environmental regulations through reduced CO2 emissions. In the future, this technology could become an industry standard for CO2 separation, allowing adopters to establish leadership in the clean energy market.
