Biodiesel Pretreatment
Optimized feedstock pretreatment for biodiesel production.
CPM provides comprehensive biodiesel pretreatment systems.
Our biodiesel pretreatment process involves several stages to prepare crude oil extracted from the back end of a dry-grind ethanol process for biodiesel production. The process typically includes degumming, neutralizing and bleaching to remove impurities like phosphatides and metals. This preparation step is crucial to reduce free fatty acids (FFA) and ensure that the feedstock is suitable for efficient biodiesel conversion.
Crude filtration is the initial process of removing large impurities and solid particles from the crude palm oil.
Degumming is the process of removing phospholipids and other gum impurities from crude palm oil to improve its quality.
Enzymatic degumming uses specific enzymes to break down and remove phospholipids, resulting in better oil yield and quality.
Neutralizing involves adding an alkali to the crude palm oil to remove free fatty acids and other unwanted components.
Bleaching is the process of removing color pigments, oxidation products, and other impurities using adsorbent materials to produce a lighter-colored oil.
Deacidification reduces the free fatty acid content in palm oil, often through distillation, to improve its stability and quality.
