A 120. MW coal plant wants to add a SOXemissions control system to reduce its emissions. The emission control system has a capitalcost of $815 per kW and reduces SOX emissions by 98% to 0.0918 kg/MWh. Assume thelifetime of the emission control system is 20 years and the power plant produces 650GWh/y. a)What is the annualized cost of this system in dollars per year if the discount rate (interestrate) is 7.0 percent/year? What if the discount rate is 4.0 percent/year? b)What is the cost per 1.0399 x 104 kWh of electricity usage (the average annual U.S.residential electricity consumption in 2017 according to the EIA) at each of the discountrates specified in part a? c)What is the cost per metric ton of SOx removed at each of the discount rates specified inpart a?

Cereal is being dried in a vertical drier by air flowing countercurrent to the cereal. To prevent breakage of the cereal flakes, some of the exit air from the drier is recycled back to mix with the the moist fresh air. For each 1000 kg/hr of wet cereal fed to the drier, calculate the input of moist fresh air in kg/hr and recycle rate in kg/hr. The available data on stream compositions is (fractions): For water: Fresh air: 0.0132 Wet cereal: 0.200 Exit air: 0.263 Dried Cereal: 0.050 Air entering Dryer: 0.066
When concentrated nitric is sold, the label contains no mention of the molarity of the acid. Instead, the label normally lists the concentration of nitric acid as a wt/wt percent and gives the specific gravity of the solution. If the solution is 68.0 (wt/wt %) and nitric acid and has a specific gravity of 1.41 kg/L, calculate the molarity of 68.0 % concentrated nitric acid. FW HNO3=63.01g/mol
