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
