SP3 Advanced oxygen separation technologies

SP-leader: Air Liquide

In SP3 - Advanced oxygen separation technologies the target is to develop more affordable oxygen production technologies. State of the art in cryogenic processes for oxygen supply to IGCC plants reveals minimum specific energy consumption of 175 kWh/ton O2 (see Table B‑2 ). Near term expectations for advanced cryogenic processes suggest 140 kWh/ton O2 as possible. Even higher expectations can be foreseen for OTM and CAR type processes (90 kWh/ton O2). However, the overall feasibility, capacity and cost of these processes are still under investigation and not validated in larger applications. The three routes for more efficient oxygen production pursued in DECARBit are:

  • Advanced non-cryogenic oxygen production techniques based on oxygen transfer membranes.

  • Materials suited for the Ceramic Auto thermal Recovery (CAR) type of process.

  • Novel and large-scale cryogenic oxygen techniques.
