1. Aspen: Reactors
Team 5:
Benjamin Morales, Joseph Cornelius, Tyler Cline, Michael Kelleher, & Connor Mules

2. Reactor Basics

3. RSTOIC and RYIELD RSTOIC:
The most basic reactor types in aspen
Useful for when extent of reaction is known
Cannot be used for kinetics calculations
RSTOIC:
For use when stoichiometry and conversion is known
RYIELD:
For use when neither kinetics or stoichiometry are known

4. REQUIL vs. RGIBBS REQUIL RGIBBS
Calculations made based on thermodynamic calculations
REQUIL required inputs:
Outlet stream & reaction
REQUIL output:
Keq at outlet stream conditions
Extent of reaction can be used as an input as well
RGIBBS
Calculations based on minimizing Gibbs energy in the system
RGIBBS required inputs:
1 or more inlet and outlet streams
RGIBBS output:
Phase and/or chemical equilibrium
Can constrain equilibrium values or heat duty or temperature approach

5. RBATCH Maximum of one feed stream Inputs
Must use a mixer before entering the reactor
Inputs
Specifications
Kinetics
Stop Criteria (Pictured Right)
Operation Times

6. RCSTR Normal Reactor Feed Inputs CSTR Specifications CSTR Reactions
Temperature, Pressure, Mole Flow Rate, Mole Fractions
CSTR Specifications
Reactor Volume, Temperature, Pressure
CSTR Reactions
Specify Reaction Kinetics, Reactants, and Products

7. RPLUG Only takes one feed stream, mixer required.
Allows for cross stream of thermal fluid
Dimension input
Catalyst loading input, RCSTR is the only other reactor that offers

8. Our recommendation: RSTOIC!
Ideal for use when yield and kinetics calculations have been done by hand or using software other than Aspen Plus
Most students already have experience using these in CHBE444
