4. Bioreaction Engineering Wash Out: 1.) Neglect Death Rate and Cell Maintenance 2.) Steady State

5. Wash Out: Maximum Production Rate = Dividing by V How does this figure relate to drinking a lot of fluids when you have an infection or cold?

23. Intro to heat effects Rate of energy in by flow Rate of energy out by flow Heat added to the system Work done by the system Rate of energy accumulation --+= Assumptions: =0

24. - Assuming no phase change during reaction - Assuming constant heat capacity Enthalpy of formation at temperature T R Heat of reaction at temperature T

25. Example – Adiabatic and no work F A0 cancels from remaining terms Usually ΔC P is small compared to other terms XX TT exothermic endothermic Example – PFR A ↔ B 1)Mole balance 2)Rate Laws 3)Stoichiometry 4)Energy Balance T XCXC Adiabatic equilibrium conversion
