Biodiesel Solutions

Methanol: Used in the chemical reaction to convert oils & fats into biodiesel.

Catalyst: Can include sodium hydroxide, potassium hydroxide flake, sodium methylate, or potassium methylate.

Oils & Fats (triglycerides): Can include tallow, distiller’s corn oil, soybean oil (vegetable oils), yellow grease (restaurants), brown grease, or other animal fats.

Pretreatment (Esterification): Converts free fatty acids (FFAs) into esters while consuming sulfuric acid, caustic, and phosphoric acid.

Transesterification: The chemical reaction that converts triglycerides into biodiesel (methyl ester).

Separation: Emulsion breaking using citric acid, acetic acid, or polysorbate.

Washing: Water used to separate methanol, FFAs, and soaps from the biodiesel. Dissolved air filtration (DAF) units are used in many plants with polymers, peracetic acid, or acid/Bases for pH control.

Drying: Includes many different unit operations (evaporators, distillation columns, etc.)

Biodiesel: Requires a stabilizer.
