Borgne, Haiti

Google Maps

Farmers of the Cooperative KGPB in Borgne, Haiti are in need of a source of income from their agricultural products

• An Essential Oil Distiller was identified as a possible mechanism to take advantage of crops

• Essential Oils can be extracted from various agricultural sources in Haiti• Vetiver• Basil• Mint• Eucalyptus• Lemongrass

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

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

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 SourcesBenchmarked 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.

Temperature & Pressure Sensor

● Need of a pressure/temperature controlling system

● Process pressure - Ordinary pressure

● Open system – operation around 100º C and 1 atm.

● Need of process monitoring – temperature and pressure gauges
