Project Statement

A liquid stream containing $60\mathrm{.}0wt\%$ ethan and $40wt\%n-$butane is to be heated from $150K$ to $200K$ at a pressure of $\frac{5}{b}ar$ with a flow rate of $2k\frac{g}{s}.$

Construct the process flowchart using ASPEN HYSYS$.$

Note: Start your simulation with Peng Robinson as the base fluid package

What is the value of $Q?$ is heat added or removed to the system?

Get the enthalpies for ethane and n$-$butane at $T=150K$ and $200K$ at $5$ bar from Husw, simulation show your results in a table $($Hint: you need to simulate one stream for reach component and get the enthalpy$)$

IP a g e

Calculate the required heat input per $kg$ of the mixture from the data obtained from Husws, simulation.

Calculate the required heat input per $kg$ of the mixture by hand calculation, state all the assumption that you made and show detailed calculation steps.

Discuss and compare your results after calculating the error $\%.$
