Biodiesel, Biochemicals

GEA supports the production of this biodiesel product in terms of both the pre-treatment of the oils and fats required and transesterification itself.

Two variants have proved themselves within alkaline refining: firstly so-called standard neutralization and secondly cold refining, which allows oils containing waxes to be winterized as they are neutralized.

• No waxes, making biodiesel more stable to cold
• No impurities, resulting in improved glycerin quality
• No gums to cause fouling in the thermal glycerin process
• No free fatty acids, reducing the proportion of MONG (Matter Organic Non Glycerin)
• No phosphates in waste water, reducing disposal costs
