Industrial processors Batch processing is convenient for small productions (no more than 10,000 t/year). Look up batch in Wiktionary, the free dictionary. ...
In the industrial continuous machines, the reaction and distillation of the alcohol is a batch processing and the decantation is continuous. Decantation is a process for the separation of mixtures, carefully pouring a solution from a container, leaving the precipitate (sediments) in the bottom of the container. ...
- In the static mixer, the esterification catalyst (most commonly sulphuric acid), the methanol and vegetable oil are mixed.
- In the reactor, esterification of free fatty acids occurs.
- In the second static mixer an alkaline catalyst (most commonly potassium hydroxide) is added to the methanol-oil mix for the transesterification.
- In the second reactor, transesterification occurs.
- In the third mixer, the product of the reaction (biodiesel, glycerol and methanol solvent) are neutralizated by introducing a mineral acid.
- In the flash vaporizer (distillation unit), the alcohol is separated. The vapors of methanol are condensed and sent to the reception unit to be introduced again in the cycle.
- The remaining products in the flash vaporizer (biodiesel, glycerol, salts and water) are sent to the continuous decanter, to separate biodiesel from the rest of the by-products.
- The light phase of the solution in the decanter is sent to the storage tank and the heavy phase (impure glycerol and salts) is sent to another storagee tank for later purification. It contains 80-90% pure glycerol, water and salts.

Glycerol, also well known as glycerin and glycerine, and less commonly as propane-1,2,3-triol, 1,2,3-propanetriol, 1,2,3-trihydroxypropane, glyceritol, and glycyl alcohol is a colorless, odorless, hygroscopic, and sweet-tasting viscous liquid. ...

Biodiesel processors for home brew users Biodiesel can be made at home. The required ingredients are any triglyceride fat or oil (animal tallow or vegetable oil, as used in cooking), a strong base (for example sodium hydroxide (NaOH) or potassium hydroxide (KOH)), and relatively pure alcohol (either methanol or ethanol). Higher (longer carbon chain) alcohols, longer than isopropyl alcohol (commonly the main ingredient in rubbing alcohol), do not work so well. Used oil for processing is often obtained from restaurants. It has been suggested that Medium Chain Triglycerides be merged into this article or section. ...

A number of different variations on methods of making biodiesel exist. It is usually made in small batch processors in the garage but some have adapted processors to fit in the backs of vans and so be transportable.
One of the difficulties faced by potential biodiesel homebrewers is making a mid-scale biodiesel processor sufficiently simple to be cheap, safe, easy to make, appropriate and that produces biodiesel of sufficient quality for their requirements. Unbiased advice can be found on many biodiesel forums dedicated to users and producers of biodiesel.
