Biodiesel Handling Products
Biodiesel is a product that is not toxic and biodegradable, so the handling is much easier and simpler than petroleum diesel fuel materials.
Activities blending biodiesel and petroleum diesel does not require complicated handling, because without the pengadukanpun both materials will be mixed with a perfect and stable.
Constraints are often complained about (but it will not happen in Indonesia) is likely due to the formation of gels at very low temperatures (usually identical to the pour point) that may occur in other countries experiencing winter.
Efforts to lower the pour point value in the series of processes to produce biodiesel will lead to declining numbers pulanya cetane number, which means lowering the quality of biodiesel produced, so the need difikirkan about the optimization process.
Another way that can be applied is to use additional aditiv which prevents the formation of the gel, it's just that these efforts need to difikirkan when the orientation of new biodiesel products are exported to countries that have winter.
