| titleOfInvention |
Cryogenic rectification system with dual heat pump |
| abstract |
A cryogenic air separation system wherein high pressure oxygen is transition-warmed against both transition-cooling feed air and transition-cooling nitrogen, supplying added reflux for the air separation and enabling column operation at higher pressures without degraded recovery. |
