Evaluation of Sulfur Dioxide Emission Control Options

There is very little decrease in sulfur content as recovery drops from 80 to 60%. The operating cost of coal cleaning (for plants in the size range of 600 t/h raw coal feed) is about $1.90/ton feed coal. The capital investment cost for a 600 t/h plant (which operates 2 shifts/day for 220-260 days per year) is broken down as follows (2, p. 13).

Progress in Chemical-Looping Combustion and

In a first step, the fuel is oxidized to CO 2 and H 2 O by a metal oxide (Me x O y) that is reduced to a metal (Me) or a reduced form Me x O y-1.If the composition of the fuel gas is expressed as C n H 2m O p, the global reduction process is given by reaction .The gas produced in this first step contains primarily CO 2 and H 2 O. After water condensation and purification, a highly concentrated
