CatalogDescription:Introductiontochemicalcalculationsemphasizingunitequations,processstoichiometry,materialandenergybalances,statesofthematter,simulationofcontinuoussteady-stateandtransientprocesses,andcasestudies.Prerequisites:CHE102,CHEM202,Corequisite:MATH182.

Justification:Thiscourseisdesigntointroducechemicalengineeringsophomorestobasiccalculationsinchemicalengineering.Thematerialcoveredisoffundamentalimportanceforasuccessfulcareerinchemicalengineeringanditrepresentsthefoundationforsubsequentcoursesintheprogram(e.g.,thermodynamics,reactionengineering,fluidflow,processde-sign,heatandmasstransfer,etc).Thetypeofcalculationsthatyouaregoingtocarryoutisthemostfrequentinthechemicalengineeringprofessionandthereforespecialattentionhastobeputon.Additionally,thestudentwillreceivetraininginproblem-solvingmethodolo-giesincludingcomputationalapproachesandwillbeexposetorealisticchemicalengineeringapplications.

EducationalObjectives:Uponsuccessfulcompletionofthiscourse,thestudentshouldbeabletodothefollowing:

•Basicengineeringcalculations.Convertquantitiesfromonesetofunitstoanotherquicklyandaccurately;define,calculate,andestimatepropertiesofprocessmaterialsincludingfluiddensity,flowrate,chemicalcompositionvariables(massandmolefrac-tions,concentrations),fluidpressure,andtemperature.

•Materialandenergybalancecalculations.Drawandlabelprocessflowchartsfromverbalprocessdescriptions;carryoutdegree-of-freedomanalyses(processbook-keeping);writeandsolvematerialandenergybalanceequationsforsingle-unitandmultiple-unitprocesses,processeswithrecycleandbypass,andreactiveprocesses.•Appliedphysicalchemistry.Performpressure-volume-temperaturecalculationsforidealandnonidealgases.Performvapor-liquidequilibriumcalculationsforsys-temscontainingonecondensablecomponentandforidealmulticomponentsolutions.Calculateinternalenergyandenthalpychangesforprocessfluidsundergoingspecifiedchangesintemperature,pressure,phase,andchemicalcomposition.Incorporatetheresultsofthesecalculationsintoprocessmaterialandenergycalculations.

•Computation.Usespreadsheets(EXCEL)andanappliedmathematicalsoftwarepackages(e.g.,MathCAD,ChemCAD)tosolvematerialandenergybalanceproblems.Text:ElementaryPrinciplesofChemicalProcessesbyFelderandRousseau,JohnWiley&Sons,3thedition,NewYork,1999.
