Presentation Transcript

  1. Chemical Engineering Second Semester

  2. Principle of chemical engineering Operation process Unit Operation

  3. chemical process ( fluid flow ) Crude material Reaction ( heat transfer) separation processes refinery products by products pure purification

  4. types of process: • Fluid dynamics: principle of momentum • Heat transfer: principle of energy • Mass transfer: principle of mass Obey conservation laws

  5. Fluid flow: Motion of particles in a fluid.Flow of fluids through granular beds and packed beds. Filtration and gravity separators Sedimentation: centrifugal separators Flow of fluids,flow in pipes and channels. Energy and momentum relationships. Pumping of fluids

  6. Heat transfer: Mechanism of heat transfer conduction By convection radiation Film coefficients and heat transfer coefficients. Shell and tube exchangers, the condensation of vapors and boiling liquids.

  7. Mass transferunit operation:separation • Distillation (l--v) • Absorption(吸收)（adsorption 吸附）(v--l) • Liquid—liquid extraction (l--l) • Drying (s—v) • Evaporation • Filtration • Gas cleaning • Sedimentation • crystallization
