WHAT IS WHAT - DEFINITIONS FOR THIS FORUM

[Believer45]

Per requests from several on the forum, the following is what is what:

Please PM me if anyone sees anything that should be added.

B20 Mix of 20% biodiesel and 80% Diesel

Bio Diesel is fuel made from oil through a process called transesterifacation. That is the seperation of the glycerine from the esters in the oil. This is what the methanol and lye do. The glycerine is the waste and the esters is the bio-d.

Blended Vegetable Oil Mixing Vegetable oil with a thinning agent to lower the viscosity of the Vegetable Oil so it pumps and injects more like diesel.

FPHE Flat Plate Heat Exchanger

RUG Regular Unleaded Gasoline

SVO is new straight veggie oil (any kind, never used). May also need heated, like WVO.

ULSD Ultra Low Sulfur Diesel

WVO is used veggie oil, usually picked up from a restaurant or food processing plant. Once processed it may need to be warmed in your tank or pickup in colder weather so your engine can use it.

I will edit as I come across clearer or other definitions.

what does harpooned tank mean?

Vinny,

check your PM's.

It's 'transesterfication'.

Transesterification (Chemical Conversion of Biodiesel)

The manufacturing of biodiesel from vegetable oils (e.g. soy, canola, jatropha or sunflower seed) or animal fats, involves the base-catalyzed transesterification of fatty acids with methanol or ethanol to give the corresponding methyl esters or ethyl esters. Glycerin is an inevitable byproduct of this reaction.

Vegetable oils as animal fats are triglycerides composed of three chains of fatty acids bound by a glycerin molecule. Triglycerides are esters. Esters are acids, like fatty acids, combined with an alcohol. Glycerine (= glycerol) is a heavy alcohol. In the conversion process triglyceride esters are turned into alkyl esters (= biodiesel) using a catalyst (lye) and an alcohol reagent, e.g. methanol, which yields methyl esters biodiesel. The methanol replaces the glycerin.

The glycerine - the heavier phase - will sink to the bottom. Biodiesel - the lighter phase - floats on top and can be separated, e.g. by decanters or centrifuges. This conversion process is called transesterification.

The conventional esterification reaction in batch processing tends to be slow, and phase separation of the glycerin is time-consuming, often taking 5 hours or more.
