Question

Q4/ Toluene gas (CH3) enters a continuous adiabatic heat exchanger at (35°C) and (300 KPa) and exits at (260°C). Superheated steam at (400°C) and (5 bar) enters to exchanger flowing counter currently to a Toluene and exits as a saturated liquid at the same pressure. 1- If (150 mol) of Toluene is fed, draw and label a process flow chart. 2- Calculate the values of inlet-outlet enthalpies. 3- Calculate the volumetric feed ratio of the two streams (m' steam fed/mºtoluene fed). Assume ideal gas behavior for the toluene but not the steam and recall. (20 Marks) Q5/ n-Butane is converted to isobutene in a continuous isomerization reactor that operates isothermally at (140°C). The feed to the reactor contains (91%) of n-butane, (6%) of isobutene, and (3%) HCL at (140°C) and (45%) conversion of n-butane is achieved. 1- Taking a basis of (100 mol) of feed gas, calculate the moles of each component of the feed and product mixtures and the extent of reaction 3 (mol). 2- Calculate the standard heat of the isomerization reaction ( KJ/mol). Then, taking the feed and product species at (25°C) as reference prepare an inlet- outlet enthalpy table and calculate and fill in the component amounts (mol) and species enthalpies (KJ/mol). 3- Calculate the required rate of heat transfer (KJ) to or from reactor (state which it is). Then determine the required heat transfer rate (KW) for the reactor feed of (375 mol/h). 4- Use your calculated results to determine the heat of isomerization reaction at (140°C) AA (140°C )KJ/mol.
