# A 120. MW coal plant wants to add a SOx emissions control system to reduce its emissions. The emission control system has a capital cost of $815 per kW and reduces SOx emissions by 98% to 0.0918 kg/MWh. Assume the life of the emission control system is 20 years and the power plant produces 650 GWh/y. What is the cost per metric ton of SOx removed? (1 metric ton = 1,000 kg = 10^6 g) Question A 120.
