Unformatted text preview: ChemE 3230 Fluid Mechanics Spring Semester, 2009 What is a Chemical Engineer ? a) An Engineer who manufactures chemicals. b) A Chemist who works in a factory. c) An Engineer who knows Chemistry. d) A highly-paid plumber. Why Study Fluid Mechanics? 1. Most chemical plants convert some fluid (liquid, gas) raw material into a more desired (usually more expensive) product. Fluid mechanics provides a framework for designing and sizing equipment for (a) transporting; (b) transforming; and (c ) storing the raw materials, intermediates, and final products. Example: Chemical Plant for Transforming ethylene and benzene into ethylbenzene -----> styrene --------> polystyrene + C C- MCM-22 / EBZ-500 + C-150 / EBM-9 + H 2 Alkylation Dehydrogenation C 2 H 5 C 2 H 5 C 2 H 3 x- BF 3 + H 2 O CH 2 CH 2 x Polymerization C 2 H 3 $0.30/lb $0.32/lb $0.42/lb $0.82/lb Chemical Plant for Producing Ethylbenzene (99 +%; 50,000 mton/yr) - ChemE `05 Fluid Flow in Piping: Q in Q out l P 1 P 2 Design Objectives Minimize pump (liquids, suspensions, slurries) and compressor (gases) cost. Minimize pipe acquisition and maintenance costs. ! P = P 2 " P 1 = f ( Q , l ) Fluid Flow in Heat Exchangers: z r ! q = g ( k f , ! T , u r ) Design Objectives Maximize heat transfer coefficient and heat transfer rate. Minimize heat loss from pipes and fittings. Example from ChemE 324 Flow in Packed-bed Reactor: Design Objectives Maximize interfacial contact and residence time of reactant(s) in catalyst bed . Minimize entrainment of particles in exiting streams. v ! X = h (v ! , K , " K ) Example from ChemE 390 Design Objectives Maximize contact between down-comer (liquid) and up-comer (vapor) streams. Minimize flooding. Flow in Distillation Columns: N T = ! ( Q g , Q L , T , P , K L , V ) Example from ChemE 332 ChemE 3230 Fluid Mechanics Course Description Fundamental principles and applications of fluid mechanics. This course teaches students how to apply mathematics and the physical sciences to analyze fluid flows in chemical process equipment (e.g. pipes, pumps, and packed columns), and to design fluids handling processes.
