PLEASE ANSWER EACH QUESTION IN THE SPACE PROVIDED. SHOW ALL WORK IN THE SPACE PROVIDED AND PUT YOU ANSWER ON THE LINES PROVIDED. NO PARTIAL CREDIT WILL BE PROVIDED. NO CREDIT WILL BE GIVEN IF THE ANSWER IS CORRECT BUT THE WORK USED TO GET THE ANSWER IS NOT GIVEN OR INCORRECT. n-Butane is converted to isobutene in a continuous isomerization reactor that operates isothermally at 150°C. The gaseous feed to the reactor contains 75 mole% n-butane; 10 mole% isobutene, and 15 mol% hydrogen chloride at 150°C. A 50% conversion of n-butane is achieved in this reaction Calculate the extent of this reaction using one mole of feed as the basis of calculation. Calculate the standard heat of this isomerization reaction. A gas stream (Stream 1) consisting of n-hexane in methane at 60°C and 1.2 at m is fed to a condenser. The dew point of the gas stream is 5°C considering hexane as the only condensable component. The gas is cooled to 55°C in the condenser, recovering pure hexane as a liquid (Stream 2). The effluent gas leaves the condenser saturated with hexane at 5°C and 1 atm. Given this information, provide answers to parts a and b. Calculate the vapor pressure of n-hexane in mmHg at 5°C and 55°C using Antoine's equation. Based upon the description of the process, fill in all missing information in the table below. Show all mass balances and any other necessary calculations clearly. Two thousand kilograms per hour of steam drives a turbine that delivers 75. kW of shaft work. Superheated steam at 5 bar enters the turbine at 200°C and the effluent stream is saturated steam at 1 atm. Assuming that potential and kinetic energy contributions to the overall energy balance are negligible, calculate the heat loss from the turbine in kW. A silicon wafer facility uses a mixture of water and sulfur hexafluoride as an etchant in their process Water at 10°C (10. mol/min) is injected into a flow of liquid SF6 at 3odegreec and the combined stream, which contains 90. mol% water, is pre-heated to 90°C at 1 atm. Note that this process requires heating two streams to produce a combined stream at a higher temperature, Calculate enthalpies and completely fill in the missing information in the table given below. The specific heat of liquid SF6 is estimated to be 205 J/mol*C Calculate the rate of heart transfer required in kw.Explanation / Answer
1 a. Taking a basis of 1 mol of feed gas, calculate the moles of each component in the
feed and product mixtures and the extent of reaction
Isomerization reaction : n-C4H10 (g) -> i-C4H10 (g)
Feed components : 0.75 mol n-C4H10, 0.10 mol i-C4H8 , 0.15 mol HCl
Product components :
n-butane balance :
0.75 mol n-C4H10 − 0.75mol n-C4H10*0.5 mole n-CH4H10 reacted/mol n-C4H10 fed = 0.375 mol n-C4H10
i-butane Balance : 0.10 mol i-C4H8 + 0.75mol n-C4H10*0.5 mole n-CH4H10 reacted/mol n-C4H10 fed = 0.475 mol i-C4H8
HCl balance = 0.15 mol HCl
Extent of reaction = |(n-butane)in-(n-butane)out|/|Vn-butane|=|0.375-0.75|/|-1|=0.375 mol
b. del Hreaction = del H formation (i-C4H8) - del H formation (n-C4H10)
= -16.9 - (-124.7) = 107.8 KJ/mol
Using Heat of formation values from the net as they are not given in the question.
