Table $1$ provides a list of process streams that should be heat integrated. The utility system is represented by steam $($ST$)$ and cooling water $($CW$)$ that are available in sufficient amounts on the production site $("$var$"$ is short for variable, which means that the amounts of utilities required are unknown and should be determined$).$ It is assumed that $T_{\text{m}\text{i}\text{n}}=10C$ gives a reasonable economic trade$-$off between operating cost $($energy$)$ and investment cost $($heat exchangers$).$
