Problem $3[30]$ Using data from Table $3\mathrm{.}14,$ determine the energy required to heat a $20$

wt $\%$ MEA solution loaded with $0\mathrm{.}4$molC$\frac{O_2}{m}ol$ solvent from $40C($the absorber column

temperature$)$ to $120C($the stripper column temperature$).$ What percentage of this energy

is used to heat up the water in the solution? Repeat for a $30wt\%$ MDEA solution.

Table $3\mathrm{.}14$ Selected heat capacities $($J$/$g K$)$ for amine$-$based CO$2$ capture $[76]$
