Q$3$: $(25$ pt$)$ A facility is considering switching from Northern Appalachia coal to

WTI oil. Assume this facility generate $100$ MW per day, and the chemical energy to

electricity energy conversion efficiency is $50\%.$

$($a$)$ How much coal and oil are needed, respectively?

$($b$)$ How much uncontrolled sulfur $($S$)$ are going to be released by each fuel?

Note $1bbl=0\mathrm{.}159m^3.$ Density of oil $=1808l\frac{b}{m^3}\mathrm{.}1$ton$=2000lb.$

$($c$)$ Is there a cost advantage in switching from Northern Appalachia coal to WTI

oil? Use the costs described in Table $8-7.$ Assume the cost of sulfur removal

is $$\frac{250}{?}$ ton and that the sources must meet NSPS emission limits for a new

electric utility steam generation unit. The NSPS $S{O}_2$ requires $97\%$ reduction

when sulfur emission is great than $1\mathrm{.}44$ tons$/100$ MW day energy output.

Data from table $8-7$:
