Description

Introduction:This course covers all the theory required to understand the basic principles behind Unit Operations that are based on Mass Transfer. Most of these Unit Operations (Equipments) are used in Process Separation Technologies in the Industry.Common examples are Distillation, Absorption and Scrubbing.This course is required for the following:Flash DistillationGas Absorption & StrippingSimple DistillationBatch DistillationBinary DistillationFractional DistillationScrubbersGas TreatingSprayers / Spray TowersBubble Columns / Sparged VesselsAgitation VesselsPacked TowersTray TowersWe will cover:Mass Transfer BasicsDiffusion, ConvectionFlux & Fick's LawThe Concept of Equilibrium & PhasesGibbs Phase RuleVapor PressureEquilibrium Vapor-Liquid Diagrams (T-xy, P-xy, XY)Equilibrium CurvesDew Point, Bubble PointVolatility (Absolute & Relative)K-ValuesIdeal Cases vs. Real CasesHenry's LawRaoult's LawDeviations of Ideal Cases (Positive and Negative)AzeotropesSolubility of Gases in LiquidsInterphase Mass Transfer and its TheoriesTwo Film TheoryMass Transfer Coefficients (Overall vs Local)Getting Vapor-Liquid and Solubility DataSolved-Problem Approach:All theory is backed with:ExercisesSolved problemsProposed problemsHomeworkCase StudiesIndividual StudyAt the end of the course:You will be able to understand the mass transfer concepts behind various Unit Operations involving Vapor - Liquid Interaction. You will be able to apply this theory in further Unit Operations related to Mass Transfer Vapor - Liquid, which is one of the most common interactions found in the industry.About your instructor:I majored in Chal Eeering with a minor in Industrial Eeering back in 2012.I worked as a Process Design/Operation Eeer in INEOS Koln, mostly on the petrochal area relating to naphtha treating. There I designed and modeled several processes relating separation of isopentane/pentane mixtures, catalytic reactors and separation processes such as distillation columns, flash separation devices and transportation of tank-trucks of product.
