OTM Solid State Combined Reformer
Progress Update
GSTC 2017
Colorado Springs

1 | Praxair Business Confidential | 10/20/2017
Praxair’s OTM Combined Reformer
Why:
The most efficient process to produce syngas
for chemicals
What:
Oxygen-based syngas supply system without
the oxygen plant
SMR inputs ATR outputs
How:
Solid-state air separation combined with
reforming in a robust ceramic membrane within
a modular, scalable package

OTM Platform
Syngas platform
– Can be optimized for MeOH, H2, GTL, CO
– High NG conversion efficiency
Modular syngas offering for CO, Chemicals, GTL
– “Oxygen free” alternative to POx, ATR and Combined Reforming
– Opportunity to pursue small CO where O2 is not available and ASU is difficult to justify
– 10% – 15% more efficient than SMR for MeOH and GTL
– Advantages validated by third parties (technology licensors)
Paradigm shift for methanol and GTL economics

Technology Readiness
Achieved commercial ceramic performance targets
– Extraordinary progress on flux, strength, creep life, degradation
– Robust glass-ceramic seals
Proved unique combined reforming process
– Demonstrated at single and multi-panel levels
– Robust to system-start up, shut-down, trips, and transients
On-Track with Supply Chain and Cost Reduction
– Tube manufacturing capacity increased to 8 MM scfd syngas/yr
– Qualifying external parties for high volume substrate manufacturing
– Shops qualified to manufacture panel array modules
– Delivering on key capital cost reduction targets
Ready for industrial scale demonstration
