Capital Cost Calculations

Capital cost is the sum of the unit reactor cost and lamp cost:

\[C_{cap,tot} = C_{cap,reactor}+C_{cap,lamp}\]
\[C_{cap,reactor} = C_F * F_{in} C_{cap,lamp} = C_l * E\]

Operating Cost Calculations

Fixed operating cost depends on the electricity demand of lamps, \(E\), as shown in the equation below:

\[C_{op,tot} = f * C_l * E\]
