A 1,000-MW electric power generating plant burns coal that has a heating value of 23,500 kJ/kg coal, sulfur content of 2.5% (by mass), ash content of 8% (by mass), and mercury content of 0.01% (by mass). The plant operates continuously 8,760 hr/yr. It has a thermal efficiency of 36%. What is the required removal efficiency for SO 2 to meet the NSPS emission standard (i.e., 1.4 lb SO2 per MWh of gross energy output). 90% 93% 97% 99.5% Consider a flue gas with the following composition: N2=71%, CO2=11%, H2O=10%, O2=8%. The temperature and pressure of the flue gas are 150C and 1 atm, respectively. The concentrations at the flue gas conditions are 20 ppm for HCI (MW=36.5). What is the actual mass concentration of HCl in the flue gas, in mg/m3. 610 mg/m3 10 mg/m3 21 mg/m3 56.5 mg/m3 Consider a flue gas with the following composition: N2=71%, CO2=11%, H20-10%, O2=8%. The temperature and pressure of the flue gas are 150C and 1 atm, respectively. The flue gas flows out of a 2.0-m diameter stack at an average gas velocity of 18 m/s (at stack temperature and pressure). If the particulate concentration just meets the standard of 20 mg/dscm, corrected to 7% O2, what is the emission rate of particulate matter (mg/s)? 17 mg/s 610 mg/s 49 mg/s 320 mg/s
