A preliminary-level economic evaluation is made using Tennessee Valley Authority (TVA) design premises with each of TVA and the Electric Power Research Institute (EPRI) economic premises to compare seven flue gas treatment (FGT) processes for removal of nitrogen oxides (NO/sub x/) from power plant flue gas. The case examined is a new, 500-MW unit burning 3.5% sulfur coal and emitting 600 ppM NO/sub x/ in the flue gas. A minimum removal efficiency of 90% for sulfur oxides (SO/sub x/) and NO/sub x/ and 99.5% for particulates is assumed. To permit comparisons of the dry NO/sub x/ FGT systems with the wet SO/sub x/-NO/sub x/ systems, which also remove particulates, the costs of both a limestone slurry flue gas desulfurization (FGD) unit and an electrostatic precipitator (ESP) are added to the cost of the dry NO/sub x/-only processes and the cost of an ESP is added to the cost of the dry SO/sub x/-NO/sub x/ process. With TVA economic premises, the wet SO/sub x/-NO/sub x/ system and dry NO/sub x/ systems (either SO/sub x/-NO/sub x/ or NO/sub x/-only processes) have capital cost ranges of 205 $/kW to 482 $/kW, and 165 $/kW to 175 $/kW, respectively. The revenue requirements range from 12 mills/kWh to 20 mills/kWh for the wet systems and 7 mills/kWh to 9 mills/kWh for the dry systems. With EPRI economic premises, the capital cost ranges of the wet and dry systems are 212 $/kW to 506 $/kW, and 167 $/kW to 173 $/kW, respectively. The levelized cost ranges are 22 mills/kWh to 35 mills/kWh for the wet systems and 13 mills/kWh to 16 mills/kWh for the dry systems. The results from each set of economic premises indicate that the wet SO/sub x/-NO/sub x/ processes are not economically competitive with either the dry NO/sub x/-only or the dry SO/sub x/-NO/sub x/ processes.
