This latest research paper finds that:
- Nitrogen rejection from natural gas by DR PSA was numerically studied.
- The separation performance of two different adsorbents were compared and optimized.
- An 85% CH4 + 15% N2 feed was upgraded to 93% CH4 with 99% CH4 recovery.
- The energy requirements were estimated using a polytropic compression model.
