Question

9. You are having second thoughts, and wonder if a CSTR in which a stream of sodium and methanol are co-fed might not be better for generation of 0.05 mol/s of methoxide (Mw 54) as a 30wt% solution in Methanol (density 800 kg/m³) required to drive the large 10 m³ scale triglyceride plant CSTRs. The CSTR would need to convert 99.9% of the sodium to be safe. Given the reaction rate of ($-R_{Na}$) = $k_1$ [Na] in mol/L.s and $k_1$ = 0.06 1/s you calculate the size of the single CSTR for the methoxide formation to be: 187 L 691 L 1870 L 17.7 L

you calculate the size of the single CSTR for the methoxide formation to be:
187 L
691 L
1870 L
