“What are some benefits of distilled biodiesel?”
The answer is as simple as 1, 2, 3 — the benefits wholesalers, retailers and fleets get with distilled biodiesel:
1. Superior cold weather performance
2. Lower carbon intensity with decreased supply and price fluctuations through feedstock flexibility
3. Easier blending
Those are the top three benefits we’ll focus on in this article. If you want to take a deeper dive into the topic, including the science behind distillation, download our free white paper on distilled biodiesel.
Superior cold weather performance
Distilled biodiesel has advanced cold flow properties because distillation does a better job than other purification methods at removing minor components that can contribute to filter plugging. Far too often people think Cloud Point is the only thing that matters when using biodiesel in the cold. Even with a higher Cloud Point, distilled biodiesel can outperform undistilled low cloud biodiesel in cold weather.
The ability to create high-quality biodiesel from a variety of feedstocks — feedstock flexibility, as we call it at REG — has a couple of big advantages. One is it can provide more nimbleness in the commodity markets.
If a particular feedstock is experiencing price or supply fluctuations, we can turn to another feedstock and know that our end product will still meet ASTM and customer specifications. This, of course, is good for our customers, too.
Another advantage of feedstock flexibility is the ability to make biodiesel from feedstocks such as animal fat, used cooking oil and inedible corn oil that can allow for lower carbon intensity (CI) scores. Carbon intensity is the measure of greenhouse gas emissions associated with producing and consuming a fuel. Some of the feedstocks with favorable CI scores can result in biodiesel with a higher Cloud Point, but with Cloud Point being less of an issue with a distilled product, users can get a fuel with lower carbon intensity that helps them reach sustainability goals and also performs well in cold weather.
So to recap, under this single benefit of feedstock flexibility comes several other advantages, including supply, price and sustainability.
Ease of blending
You may be sensing a theme related to the removal of minor components in the distillation process — and it has yet another benefit. It helps create the purest type of biodiesel. A purer biodiesel means there are fewer minor components. Fewer minor components means less effort is required to fully mix the biodiesel molecules and petroleum diesel molecules.
