IF YOU HAVE QUESTIONS ASKDURING PRESENTATION


3/25

Outline

How we started

How things work now

Things weve learned

Future goals


4/25

How we started

Student group of 5

chemical engineers

No place on campus

A professors, wifes ,brothers,


5/25

Move to Drayton Farms

End of Summer 2008

Matt McShane

contructs an

appleseed reactor

Chemical engineers

come to operate

equipment


6/25

Our Setup


7/25

without people in front


8/25

Settling Tank

Secondary

containment!

Raise storage off

ground


9/25

Clean Oil Transfer Pump

Not-self priming

Kept below oil line

Pumps well


10/25

Winter Time Oil Transfer

Very hard to pumpcold oil

If possible, keep andcollect oil warm

Avoid saturated andmonounsaturatedoils


11/25

Clean Oil Transfer Pump


12/25

Reactor

60 gal water heater

1500W heatingelement on

temperature

regulator

Max fill is 50 gal


13/25

Titration

We titrated at first

Now we dont

~1400 g KOH/ 8 galMeOH works okay for

us in a base-base rxn 75% MeO-, react, drain

glycerol, add rest, react


14/25

MeO- Mixer and Storage

Shake mixed

HDPE

NPT valve for loading

Spigot for emptyinginto reactor andreleasing pressure


15/25

Draining Glycerol

Let settle: During rxn for 20-30

min

End of rxn for 1 day

Valve at bottom

Taken to IBC storage BD and Glycerol

separate

Later will distill glycerol


16/25

27/3 Test

27 mL MeOH-

3mL BD mix

No oil residue!

Good testing=happy engine!


17/25

Wash Tank

Water mister at low

volumes


18/25

Water Misters

Fogg-It Misting Heads

$16 for 0.25 and 0.5 gpm heads

at Utah Biodiesel Supply


19/25

Wash Test

2 parts biodiesel: 1

part water

No soap curds in the

water

Water clear-ish


20/25

Drying Tank

Air bubbler

1 kW Heater- no

insulation

Clear to bottom

Note poorplumbing


21/25

Final Product Storage

55- gal barrels

Long-term considerbiocides

Winter time requiresanti-gelling additives

Or urea process


22/25

Construction Notes

Have secondary containment

Include methanol recovery and glycerol purification in originaldesign

Check system for leaks with oil or methanol first

Insulate everything your heating and include temperature control

Having a compost pile is nice

If you want to operate year-round make sure the place is insulatedand can be heated safely


23/25

Not on Your Own Property?

Keep good communications with owners and

workers

Outline financial and biodiesel agreements

before getting started

Calculate cost savings from using homemade

biodiesel vs diesel


24/25

Future Goals

Larger, more automatedsystem

Less time per gallon

Smaller learning curve

Incorporation of fuel intoUniversity needs

Clean electricitygeneration
