3. Previous Questions What type of catalyst will we be using in the primary reformer? What is the lowest purity of oxygen the oxygen fuel booster can operate with? Impurity concerns iron ore feed.

4. Design Basis 0.126 mmlbmols/day of natural gas feedstock will be supplied for process from Gas Treatment Plant; natural gas is the main source for Carbon for the reformer Supply the back-end CO 2 to Industrial Gases Plant, 0.0518 mmlbmols/day Air Separations and Syngas Plant will supply 0.004 mmlbmols/day of O 2 for the Oxy Booster in ration (0.9 O 2 : 0.1 N 2 )
