Abstract

This dissertation analyzed the technical viability of blast furnace slurry gasification with the objective of using the obtained gas at ArcelorMittal Tubarão. The process was simulated using an equilibrium program, the TCW - Termochemical Information and Equilibrium Calculation. Three mixtures were considered for gasification: a) 100% high volatile metallurgical coal (the base of the mixtures), b) 15% slurry and 85% coal, and c) 25% slurry and 25% coal. The two main parameters that defined the technical viability of the blast furnace slurry were the mixture Low Heat Value (LHV) and the temperature ranges for work in the gasification reactor. The LHV was calculated from the molar fractions of H2 and CO in the gas obtained in the simulation
