Biodiesel is a mixture of hundreds of different hydrocarbons. The specific mixture depends on the feed stocks (vegetable oil, animal fat, waste oil…) used and the processing methods.
Understanding which components are present and their concentration can be crucial to optimizing plant operations. Optimizing processing, blending and feed stocks maximizes profits.
The fractional distillation of biodiesel can separate biodiesel into its various components (fractions). Understanding the distillation curve and the components in the complex mixture is an important factor in understanding how to optimize a biodiesel manufacturing plant.
Choose the fractional distillation system that is right for your lab.
System | Boiling Flask Range | Application |
---|---|---|
Pilot Scale | 50 – 1000 liters | Large Scale Research |
Lab Scale | 1 – 50 liters | Lab scale research |
Mini Scale | 50 – 1000 ml | Research on small sample sizes |
Micro Scale | 10 – 100 ml | Research on micro sample sizes. |
There are now low limits on the sulfur content of diesel. Understanding how the various sulfur compounds are distributed throughout the boiling range of the biodiesel can lead to smarter decisions on where to make a final distillation cut between the biodiesel and the biodiesel residue.
Carbon residue is also an important property of a biodiesel. Research can show how to optimize the distillation process to get the most product while still meeting carbon residue standards.
