Abstract
AN IMPROVED METHOD AND APPARATUS FOR FORMING METALLIZED IRON BY DIRECT REDUCTION OF PARTICULATE IRON OXIDE IS DISCLOSED. IN THE IMPROVED METHOD AND APPARATUS, THE SPENT REDUCTION GAS IS RECYCLED FROM THE REDUCTION FURNACE THROUGH A COLLER-SCRUBBER AND A CATALYTIC-CONTAINING STOICHIOMETRIC GAS REFORMER. IN THE COOLER SCRUBBER, THE SPENT REDUCING GAS INTERACTS WITH SCRUB WATER. DUST HAVING AN AFFINITY FOR SULFUR IS RECOVERED FROM THE PROCESS AND ADDED TO THE SCRUB WATER CAUSING SULFUR IN THE SPENT REDUCING GAS TO FORM SOLIDS WHICH PRECIPITATE OUT AND ARE REMOVED AS SOLID WASTE. LOWERING THE SULFUR CONTENT OF THE SPENT REDUCING GAS REDUCES THE SULFUR CONTAMINATION OF THE CATALYST AND IMPROVES THE EFFICIENCY OF THE PROCESS.(FIG. 1)
