Biodiesel Pretreatment

Optimized feedstock pretreatment for biodiesel production.

We are pioneers in biodiesel pretreatment solutions, offering advanced technologies to ensure the highest-quality feedstock for biodiesel production.
CPM | Crown RD Ready™ Preatreatment System efficiently removes contaminants from various feedstocks — including vegetable oils, animal fats and recycled greases — preparing them for the transesterification process to produce biodiesel.

Advantages Include:

  • All equipment is typical for an industrial process and not simply a collection of tanks and plastic tubing
  • Using a proven design ensures maximum equipment reliability and product quality
  • Pretreating any substandard fats and oils saves on capital and operating expenses in the transesterification plant—an overall savings for an integrated plant
  • A flexible pretreatment design allows a variety of biodiesel feedstocks to be processed in the same equipment
  • Straightforward process, which is similar to proven edible oil refining technologies
  • Pretreatment can be designed to also allow the production of edible oil in order to take advantage of the ups and downs of variable industry conditions
  • Phosphatide and fatty acid byproducts are similar to the ones produced in an edible oil plant—enabling byproduct sales to an existing market

Biodiesel Pretreatment processes

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​.
