Winter Time Oil Transfer
Very hard to pumpcold oil
If possible, keep andcollect oil warm
Avoid saturated andmonounsaturatedoils

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

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

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

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
