Syllabus

Part I- Modeling of Chemical Processes

o Modeling procedure

o Some needed definitions

- SI and US units

- Concentration definitions in gas and liquid mixtures

o Total mass balance

- Example 1: Modeling of two isothermal interacting tanks

o Component mass balance without chemical reaction

- Example 2: Modeling of an isothermal mixing tank

o Introduction to chemical reactions

- Kinetic modeling of chemical reactions: Power law model

- Concept of chemical equilibrium and chemical equilibrium constant

- Example 3: Calculating the output of an equilibrium reactor (Steam-Methane reforming)

o Component mass balance in presence of chemical reaction

- Example 4: Modeling of a continuous stirred-tank-reactor at isothermal condition (CSTR)

o Energy balance

- Definition of enthalpy in gas and liquid mixtures

- Introduction to fluid mechanics: Laminar and turbulent flow

- Introduction to heat transfer: Conduction and convection

- Definition of heat transfer coefficient

- Definition of dimensionless numbers: Reynolds, Prandtl and Nusselt numbers

- Example 5: Modeling of a non-isothermal mixing tank

- Example 6: Modeling of a double-pipe heat exchanger

- Example 7: Modeling of a shell and tube heat exchanger

o Introduction to mass transfer

- Molecular diffusion (Fick’s first law)

- Definitions of component mass flux

- Definitions of mass transfer coefficient and dimensionless numbers (Schmidt and Sherwood)

- Example 8: Modeling of a tubular reactor

Part II- Review of Feedback Control Loop Elements

o Control valve (types, sizing and modeling)

o PID controllers (types and modifications)

o Tuning of PID Controllers (offline and online methods)

Example 9: Temperature control of a CSTR
