Cleaning coal and sequestering its emissions significantly raises the perBT­U price of what would otherwise be an inexpensive fuel. While selling byproducts like gypsum or commercial CO2­ for sodas and dry ice can offset the price of clean coal technologies, a charge on carbon could make emissionreduction financially realistic.

Corex Process for Production of Iron – IspatGuru

+

Corex process distinguishes itself from the blast furnace route by (i) direct use of noncoking coal as reducing agent and energy source, (ii) Iron ore can be directly and feasibly charged to the process in form of lump ore, and pellets, and (iii) use of pure oxygen instead of nitrogen rich hot blast.
