The process begins with the acidulation of raw glycerin as pictured. The top layer consists of fats/vegetable oils. Next, there is an interphase commonly known as “rag layer.” At the bottom is the lighter glycerin layer that will also be mixed with methanol and excess water.

The processed glycerin has been acidulated to remove the fats from the starting product and then demethylated using heat & vacuum. It can be used as livestock feed, exported, further processed, or used as an industrial anti-freeze agent in the winter.

The vegetable oils and fats are decanted from the glycerin after the acidulation process. They are then run under heat, vacuumed and then filtered. The end product provides fats/oils that can be fed to livestock as they are <0.15% methanol and < 1 MIU (moisture, impurities and unsaponifiables).

Wet methanol is extracted from the glycerin during the demethylization process. This wet methanol will be distilled to provide reclaimed methanol which is methanol with <1,000 ppm water.

The wet methanol can then be further distilled to create the end product of reclaimed methanol. This is sold back to biodiesel plants as a production input.
