Project description
• Created a model for biodiesel production by plug flow reactor
• Validation of model• Learn Simulink• Renewable energy sources

Flow scheme

Simulink model
• Ten CSTRs in series for plug flow reactor• Settling tank for buffer effect and separation• Distillation between biodiesel and methanol• Flash of methanol from glycerol

Operating condition
• Soyabean oil, assumed one component for simplicity
• 600C • 100% excess methanol• NaOH catalyst

Model validation
• Single units and system• Change in flowrate• Disturbance in feed composition and methanol
excess• New product requirements in purity

Reaction Chemistry

Reactor validation• Removal of
methanol in feed
• No conversion• Change
through reactors
![Page 10: 1 Modelling of Biodiesel Production Marianne Øien Supervisors: Sigurd Skogestad and Chriss Grimholt.](https://reader036.fdocuments.net/reader036/viewer/2022062905/5a4d1b077f8b9ab059988e0d/html5/thumbnails/10.jpg)

Settling tank response• Increased
biodiesel fraction upstream
• Smooth out disturbance downstream
• Total flow conserved

System disturbance• Application of 10%
flow disturbance• Smooth output
disturbance• Excess methanol
reflected in vapour and liquid flow

Further work
• Include industrial size, amounts and data– Optimal flows for nominal operation– Tuning and control – Industrial expected disturbances
• Reducing computation time• More complex validation cases
