The stack gas flowrate of a power plant is $30,000$ m$3/$hr$.$ Uncontrolled emissions of SO$2,$ HCl$,$ and HF in the stack are $750,150,$ and $15$ mg$/$m$3,$ respectively. The regulation states that stack gas emissions of SO$2,$ HCl$,$ and HF must be under $50,10,$ and $1$ mg$/$m$3,$ respectively. Calculate the required total limestone $($CaCO$3)$ dosage $($in ton$/$day$)$ for the design of a wet$-$scrubber system to reduce SO$2,$ HCl$,$ and HF to the limits $($MW of CaCO$3$: $100,$ SO$2$: $64,$ HCl: $36\mathrm{.}5,$ and HF: $20$ kg$/$kmol$,$ the stoichiometric ratio for CaCO$3$: $1\mathrm{.}2).$
