Summary of (1)
-applied rigorous models and simulations.
-developed ‘sinter’ for cross software communication to allow excel and Aspen plus models to compute
Flue gas desulfurization (FGD)
-steam flow is 3,670,000 lb/h at 1050 deg F and 2415 psia in a 550MW pulverized coal power plant
-0.492% mechanical loss on GE turbine
88%-90% efficiency on everything is assumed
Limestone slurry-> flue gas-> gypsum …to reduce SO2 in flue gas to about 54ppm.
-cooling tower (primarily by evaporation, partially by heat transfer to air.)
-US Department of energy (DOE) requires reduce in fresh water withdrawal and consumption by 70% by
2020 and at 50% less that dry cooling costs.
-DOE goal to capture 90% CO2 with less than 30% increase in cost of electricity
