First Finished Batch of Biodiesel!

As the new president of Biodiesel@MIT, I am very proud to say I finished my first batch of biodiesel. This batch actually started in March, but due to a broken pump, it didn't get finished until last night.
After doing a second magnesol treatment and water wash, the biodiesel was finally ready to go through the last magnesol treatment and filtration (correction to last post; the biodiesel and magnesol go through two filtrations: 10 microns and 1 micron, not 100 and 10). As I believe I mentioned last time, the first filtration did not go properly because the filter did not fit in correctly, but it was obvious that everything worked the second time around because the whole filter was completely caked with magnesol (as it should be). It was very heavy and difficult to get out, but after slowly draining it, I was able to replace it with the 1 micron filter and perform a second magnesol treatment. We have decided to reuse the filters for at least two batches, as long as well we let the filters dry out and we are able to scrape most of the magnesol out.
To make room for the new biodiesel, I tried out our new barrel pump to consolidate our uncertified biodiesel into one drum. The pump is very simple; it screws into the larger bung, and a hand pump is used to draw out the liquid inside. The good people at Utah Biodiesel Supply added braided tubing to the kit to replace the normal spout, making it much easier to transfer biodiesel among barrels.
Today we received two new drums to be used for the blending of B5 and B10 that will be used in the landscaping equipment on MIT's campus. This is a very big step for Biodiesel@MIT, as this has been our goal since before the processor was even installed.
Stay tuned for more news from Biodiesel! There's a lot happening this summer, so if you would like to get involved, please contact me at hojnacki@mit.edu.
