Question

Assuming compliance with NAAQs, predict the daily rates of emissions of particulates, NO_s, SO_s, and Hg from a coal-fired power plant producing 1000 MW of electrical power at an overall thermal efficiency of 40%. Assume coal contains 1.6% sulphur and has a heating value of 10, 500 Btu/lb. Estimate the daily emissions of particulates from a solid-waste incinerator emitting oat 0.18 g/dsem. The incinerator burns 50 tons per day and exhausts gases in a ratio of 20 kg of gases per kg of feed. Assume the gases exit at 200C and 1 atm. Also assume that the gases have an overage molecular weight of 31, and contain 12% CO_2 and 8% H_2O as emitted. An exhaust stream from a reactor consists of 85% air and 15% NH_3(by volume). The exhaust is treated in a packed scrubber as in the figure. Calculate the rate of NH_3 leaving the vent stack, in pounds per day.
