Process description of MILENA

MILENA an indirect gasifier

Both reactors in one refractory lined reactor vessel

100% carbon to gas ratio

o Resulting in carbon free ash, less waste,

cleaner waste & safer waste

o Resulting in a higher cold gas efficiency

(5 to 15% higher on LHV basis)

Separate flue gas exhaust, no or minimized nitrogen

dilution of the product gas

o Compared to air blown gasification a 3 to 4

times higher heating value.

o Compared to oxygen/steam blown gasification a

much higher efficiency (no ASU parasitic), while

still having 60% more heating value

o Very suitable for gas turbines
