High Efficient Heat Exchange ReformerPrinciple:

● Combines conventional SMR with heat exchangereforming in a single reactor and compact firebox.Helical heat exchange coils directly embedded inreformer tubes.

● ~20% reforming duty is provided by internal heatexchange which improves the energy utilizationand leads to reduced firing.

Main benefits:● Reduced firing leads to reduced CO2 emissions,

specific higher H2 yield and zero steam export.● Capex improvement due to bottom fired furnace

and smaller flue gas system.

SMR-X provides 4-5% lower TCO compared to conventional SMR with zero Export Steam
