LiquidLiquid Extraction of Glycerol from Biodiesel

1
Liquid-Liquid Extraction of Glycerol from
Biodiesel

• Project Proposal

2
Background Summary

• The Overall Reaction

3
Mission

• Determine the highest volumetric flow rate and
  best separation of glycerol from biodiesel with
  three different continuous flow extraction
  systems
• Find an optimal testing method for quantitative
  determination of glycerol in biodiesel and/or
  water
• Develop a ternary phase diagram for glycerol,
  water, and biodiesel

4
The Team

• Becky Solano - Box type mixer settler
• Gabe Montero - Packed column extractor
• Trevor Binney - Podbielniak extractor

5
The Equipment

• Box Type Mixer Settler Unit
• Currently set to run cross current extraction

6

• Packed Column Unit
• Parameters to be determined

7

• Podbielniak Extractor
• - Centrifugal

8
Design of Experiments

• Box Mixer Settler - Simplex
• See if actual and expected results are equivalent
• Column Extractor - 2K factorial design
• Vary volumetric flow rate
• Vary relative ratios of biodiesel and water
• Podbielniak Extractor - 2K factorial design
• Vary relative ratios of biodiesel and water
• Vary rotational speed of extraction unit

Data Analysis Plan

• Use ternary phase diagram to model box type
  behavior.
• Use mass transfer equations to model column
  behavior.
