Transesterification


  • 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
  • Centrifuges are not used in the process, eliminating expensive maintenance issues
  • Gravity separation of methyl ester from other product phases eliminates maintenance headaches and the high cost of high-speed rotating equipment
  • Specifying a high-quality feedstock ensures that process upsets are minimized because feedstock variations are taken care of in pretreatment, minimizing the total processing cost
  • Wash water is not discharged as a waste stream


  • Straightforward process standard to the biodiesel industry
  • Catalyst used is standard and readily available, no licensing needed
  • Flexible design allows processing of one or multiple types of pretreated feedstock in the same equipment
  • Feedstock specifications to the plant are typical for a partially refined edible oil to ensure the transesterification plant will be able to process any kind of oil or fat into biodiesel
  • Long reaction and separation time ensures maximum efficiency with a high product conversion
  • Crude glycerin byproduct from the process is the same or better quality than the crude glycerin typically processed in existing glycerin refining equipment at soap plants
  • Wash water used for cleaning the methyl ester is reused in the glycerin cleanup section and combined with the crude glycerin
