Re: [biofuel] Testing iodine value? Degumming?
Hello Mike, welcome I'm a bit of a newbie on the subject, I tried to search the messages for iodine but aparently none in the subject line. I suspect you're using the wrong message archives. DON'T use Yahoo's archives! It's useless. It searches 50-60 messages at a time or something, which means that it would take about 700 pages to search the whole list, Yahoo pages at that, plus the ads. Use the list's independent archives, linked at the end of every message and at the list's homepage at Yahoo: Biofuels list archives: http://archive.nnytech.net/ It's a treasure house of information on all aspects of biofuels, especially biodiesel - it contains 35,000 messages over the last four years, many of them from leaders in the field worldwide. It's provided and maintained by list member Martin Klingensmith, with powerful, fast and efficient searching, and no ads. If you search for iodine there, you get this: http://infoarchive.net/sgroup/biofuel/?keywords=iodinetime=6monthsus ertime=2002-12-31 Reading the messages there, if you hit Click here for more on this subject it'll show you the whole thread in a clickable table at the top. Also: http://infoarchive.net/sgroup/BIOFUEL/34769/ http://infoarchive.net/sgroup/BIOFUEL/34844/ I have read a good amount and am weighing out a lot of factors before playing with this idea. Could someone give me a link or explain what the iodine value of the fuel relates to? I can't recall if this refers to svo or to processed fuel. Both. There are several tables detailing iodine values here: http://journeytoforever.org/biodiesel_yield.html Oil yields and characteristics See: Oils and esters characteristics http://journeytoforever.org/biodiesel_yield.html#oils_esters Iodine Values explained: Iodine Values -- High Iodine Values -- Talking about the weather http://journeytoforever.org/biodiesel_yield.html#iodine Fuel properties of fats and oils http://journeytoforever.org/biodiesel_yield.html#fuelfats National standards for biodiesel: http://journeytoforever.org/biodiesel_yield.html#biodstds Also as far as svo goes how exactly would one go about degumming svo? In certain cases, particularly with oils containing substantial amounts of phospholipids (e.g. soybean oil), a primary treatment called degumming is performed by adding 2 to 3% water, agitating the mixture at 50¼C and removing the hydrated phospholipids by means of settling or centrifugation. In the physical refining process, degummimg is performed by adding phosphoric acid to ensure phospholipid separation instead of water. http://alfa.ist.utl.pt/~fidel/creac/reac.html Chemical Reactions of Oil, Fat and Fat Based 3. Processing of raw materials 3.4. Refining - production, storage and packaging of refined oils a) Settling and Degumming B. Degumming Crude oils having relatively high levels of phosphatides (e.g., soybean oil) may be degummed prior to refining to remove the majority of those phospholipid compounds. The process generally involves treating the crude oil with a limited amount of water to hydrate the phosphatides and make them separable by centrifugation. Soybean oil is the most common oil to be degummed; the phospholipids are often recovered and further processed to yield a variety of lecithin products. http://www.iseo.org/iseo/ffo_6-7.htm#7 Food Fats and Oils Chapters 6 7 Best wishes Keith I understand this is one of the major factors that could stick rings and cause varnish deposits. If I recall correctly this applies to only some sources of oil type. Thanks for the info, mike Yahoo! Groups Sponsor ~-- Yahoo!
