Project Background
What is an Essential Oil Distiller?
Device that extracts oils from plant matter:
1)
Water is boiled to create steam
2)
Steam is passed over plant matter
3)
Oils from plant matter are extracted with steam
4)
Steam & oil rise up and travel to condenser
5)
Mixture is exposed to cool water and condenses
6)
Oil is separated from water

We want to sell the produced oils to local “Fair Trade” stores in the Rochester area

Project Background
Fuels
Most ‘traditional fuels’ in Haiti are:
•
Costly
•
Non-renewable
•
Non-sustainable
Therefore, there is a need for a renewable and sustainable fuel source to
help power our essential oil distiller
•
Solar Energy – abundant sun in Haiti
•
Photovoltaic
•
Thermal
•
Methane – from biodigesters
P15484 • Solar Assisted Essential Oil Distiller • Week 3 Project Definition Review
Current State
Right now, farmers in Borgne, Haiti:
•
Have little to no source of income
•
Plant crops purely for consumption
•
Are faced with deforestation and errosion problems
•
Move to larger cities in hopes of finding work

Desired State
We aim to:
• Create a feasable source of income from distilled oils
• Provide an environmentally friendly solution that does not deplete
existing fuel sources or require reccuring fuel purchases
• Form a basis for future MSD projects to build upon, improve, and
scale-up
P15484 • Solar Assisted Essential Oil Distiller • Week 3 Project Definition Review
Deliverables
● Working prototype
● Maximize use of sustainable energy resources
● Low maintenance and operation cost
● Produce oil with sufficient quality to be marketed
● A potential source of income for Haitian farmers
● A starting point for future MSD projects

Project Benchmarking
Distilling Systems
Benchmarked 10 distillers including home/hobbyist size, industrial size, and moonshine
distillers
Key Findings
● Dry steam systems provide the highest oil extraction but is usually reserved for high
volume applications due to cost of the equipment
● Stainless steel is the most widely used material
● Most common fuel sources: propane, electric

Heat Sources
Benchmarked a variety of different heat sources, with the goal in mind of producing
steam throughout the entire process time of the vetiver plant while using sustainable
energy sources
Key Findings:
There are many ways to create heat, but due to the long process time of the vetiver plant
(12 hours) it may be difficult to rely solely on sunlight as an energy source.
