Biodiesel distillation

Ways towards ultra-low sulphur biodiesel

Biodiesel distillation does not only attain the low monoglyceride and low Cold Filter Plugging Point results, the process reduces the Sulphur content at the same time. Sulzer has established a polishing process to assure the distilled biodiesel Sulphur content is less than 10ppm. “Have a peace of mind in your biodiesel quality and conform with the legislation”.

biodiesel distillation process chart

Biodiesel distillation was originally designed to purify trans-esterified biodiesel, separating components  precipitating at low temperature. Through the distillation biodiesel can be used at low ambient temperatures (winter grade biodiesel). Moreover, the colour of trans-esterified distilled biodiesel is enhanced from yellow to near colourless.

The process is applicable for acid esterified biodiesel and pyrolysis biofuel to also reduce or even remove contained Sulphur . 

Our distillation plant features:

  • Winter grade biodiesel product
  • Low Sulphur biodiesel product (for acid esterified biodiesel or other high Sulphur biodiesel)
  • Full ISBL, skid supply or customisable scope of supply & services
  • High yield of FAME by addition of post distillation (candle evaporator)
  • Very low monoglyceride in product
