Question $2$

Figure Q$2$: Process Flow Sheet $($PFS$)$ for question

For the process shown in Figure Q$2,$

$(2$a$)$ Set the utility targets and establish the pinch temperatures for a minimum approach temperature of $293$ Kelvin

$(2$b$)$ Design a Maximum Energy Recovery Heat Exchanger Network $($HEN$)$that meets the utility targets that were set in $(2$a$)$ above.

$(2$c$)$ Give a grid diagram representation of the HEN in $2b$

$(2$d$)$ Establish the temperature profile for stream $1,$ stream$2,$ stream$3$ and stream $4$

$(2$e$)$ Calculate the log$-$mean temperature difference for each stream match in the HEN of $2e.$

$(2$f$)$ Calculate the heat transfer area for the HEN in $2c$

$(2$g$)$ Estimate the heat exchanger cost for the HEN in $2c$

Assume constant Overall heat transfer coefficient of $(RegN\frac{o}{100})k\frac{w}{}C{m}^2$

Where RegNo is the last two digits of your registration number

Exchanger cost $(NGN)=53970A^{0\mathrm{.}65}$ where $A$ is total area in $m^2$
