That would much simplify the process, if it can be done at that low of temps. This is not for 'food-quality' alcohol. Just fuel to be run in my '76 Chevy pickup. It isn't real fussy, as long as it is a flammable liquid. It runs on Diesel fuel to Isopropyl alcohol, to a little used oil dumped in occasionally. If I can get 180 proof, I believe it will be perfect for my use. Motie Yahoo!

I may have to further purify a small sample occasionally for 'lab tests'! LOL I'm looking for anything over 90% for fuel purposes. If the vacuum can achieve a 50% product, I can distill it much more efficiently than if I am starting from a wash of only 14%. I would like to initialize with a 100 gallon tank, and add a couple more if the process works. The tanks could work around the clock. I would only have to spend a couple of hours daily to vacuum off the excess alcohol, and throw in more feedstock. For fuel purposes, I'm not concerned with "heads" or "tails" or any 'off-taste'. A little Methanol won't worry me. If I need a 'lab sample', I can draw off a gallon or two, and reflux it to needed quality levels.

RE: [biofuel] Diesel never smelled like this
Have you done any work on making the residue from the still fit for human consumption? By Raw -Original Message- From: Keith Addison [mailto:[EMAIL PROTECTED] Sent: Saturday, 09 February, 2002 2:45 AM To: biofuel@yahoogroups.com Cc: biofuels-biz@yahoogroups.com Subject: [biofuel] Diesel never smelled like this http://www.denverpost.com/Stories/0,1002,53%257E385631,00.html Denver Post.com - Diesel never smelled like this Biodiesel fuel nontoxic, veggie By Erin Emery Denver Post Southern Colorado Bureau Thursday, February 07, 2002 - PETERSON AIR FORCE BASE - A ferry from San Francisco to Alcatraz, U.S. Postal Service trucks in Manhattan and noncombat vehicles at Peterson Air Force Base are all powered by it. Biodiesel. It is a renewable, nontoxic diesel fuel that is made from vegetable products such as soybean oil and canola oil, along with animal fats and even recycled cooking grease from the neighborhood McDonald's. "It smells like your kitchen rather than your garage." said Gene Gebolys, president of World Energy Alternatives, the nation's largest biodiesel provider. Snowplows, pickup trucks and refueling vehicles that transport jet fuel to airplanes on the flight line at Peterson have since October been using a product called B-20, which is 20 percent biodiesel and 80 percent diesel. "It's been a success for us so far," said Master Sgt. Mark Trolio, chief fuels operator for Air Force Space Command. "Our vehicles are smoking less, and they are starting smoothly." Biodiesel doesn't have to be mixed with regular diesel for top performance, advocates say, but uncut biodiesel is mostly used in warmer climates. Biodiesel is the fastest-growing alternative energy in the United States. More than 150 public and private commercial fleets across the United States are using it because it has tremendous environmental benefits, it reduces the nation's reliance on foreign oil and vehicles don't have to be retrofitted for it. According to research commissioned by the National Renewable Energy Laboratory, operated by the U.S. Department of Energy, vehicles that burn biodiesel have cleaner emissions. In fact, biodiesel reduces cancer risk over diesel vehicle emissions by as much as 94 percent for 100 percent biodiesel and 27 percent with B-20. It's been called everything from "veggie power" to the "green" fuel for its environmental advantages, but bio-diesel is attracting a lot of attention primarily because companies don't have to spend money to retrofit their fleets, and vehicle performance doesn't suffer. "This is the easiest (alternative fuel) you can go to," Trolio said. "You can convert to biodiesel by emptying the fuel tank. All you have to do is make sure the tank is completely empty. It's a program that is so simple to get into. It's a wave, and we're ahead of that wave. Clean air - that's the biggest benefit to me. Who would not like cleaner air?" The drawback to biodiesel: It costs about 12 cents to 15 cents more a gallon than fossil fuels. Nevertheless, six U.S. cities already have biodiesel for sale at the pump, though most biodiesel is sold to fleets operated by companies or governments. The technology has been around since 1895, when Rudolf Diesel used vegetable oil to power an engine. It has only been in the last decade that economic and agricultural conditions have ignited interest in biodiesel, which could displace 2 percent of the nation's petroleum at full production capacity, Gebolys said. As a response to mad-cow disease in Europe, farmers discontinued the practice of feeding animal content back to animals. When cattle were allowed to revert to vegetarianism, there was an increased demand for soybeans but not soybean oil, creating a glut of oil and a plunge in vegetable oil prices. The government offers subsidies to people who buy biodiesel to offset losses to farmers. "Biodiesel is not just for agriculture anymore," Gebolys said. "About once every 10 years, we get a strong reminder of just how dependent we are on foreign oil and why we shouldn't be. We need to find new uses for our agricultural oil excess, and we need to find new sources of domestic clean energy. So it seems pretty clear to us that we can play a pretty important role."

The relationship of pressure to yeast viability is an unknown to me but if the liquid column is deep enough that should establish a viability zone and a piece of filter (plastic or plasticized paper?) could keep all the yeasties happy below that barrier. As to vapor pressure I think you are asking what it boils at. Perhaps you can find that on the web or in the library. You will probably use less energy purifying by freezing rather than vaporizing The depression in degrees C for ethanol/water is % ethanol depression degrees C 52.09 10 4.47 15 7.36 20 10.92 30 20.47 40 29.26 50 37.67 60 44.93 68 49.52 I think freezing H2O only uses 1/3 as much energy as evaporating. Better check that as my memory isn't what it used to be. Another way, since it can be slow, is a cold trap in a sealed system. The alcohol will transport faster than the water. Vacuum systems where you pressurize the output of the pump in a cold trap have the product going through a pump and contamination is a given. If not for human consumption I suppose it doesn't matter but the energy requirements are higher than just a trap using ambient heat to transport the product. It doesn't have to boil and the cold trap condenser heat can be put back in the source vessel if using a refrigeration system. If your tank is at 125 F I would think 75F would get condensate at a good enough rate to keep concentration below yeast toxicity. Could get 75F probably by running household water through a tank and then to house. Most water is 55F or so I would think. I assume you use the sun to heat your tank. Slowest process of all but uses the least energy. Just some meandering round Robin Hood's barn but I think there is a seed or two in there.

Re: [biofuel] Re: ethanol distillation
there are turbo yeasts available that will withstand 20%+. with sufficent vacuum you can boil water at room temp. i would question whether the yeast's ability to propagate (and therefore produce ethanol)would be affected by a low vacuum.i think that you are pursuing an interesting avenue of research. i will try to dig up some info on boiling ethanol at different vacuums. regards, roger ([EMAIL PROTECTED]) > --- In [EMAIL PROTECTED], "kirk" <[EMAIL PROTECTED]> wrote: > > I think yeast croak or really slow down at 14% or higher.(14% > =28proof) > > > That is also my understanding.

[biofuel] Re: canola vs. soy oil... stuff...
Keith, I have made a couple jpg files showing the basics of the iodine test. I could also attach a text file or something to explain the whole procedure, but basically, what an iodine test does, is not to show the amount of double bonds, but how reactive those bonds are (the more double bonds are broken and saturated by iodine, the fewer double bonds remain, and the reaction rate slows down) The iodine number is actually the amount of iodine consumed by an oil expressed as the amount of iodine in centigrams vs. the amount of oil in grams. The number is expressed as a percent (since dividing centigrams by 100 will give you grams) Here is a website that shows basically what the iodine test entails (this is the modern procedure in an analytical chemistry lab) http://manuals.dot.state.tx.us/dynaweb/colmates/mtp/@Generic__BookText View/150943 > > > >I could draw up a diagram and post it to the files section if anyone > >has questions. > > That would be useful, but the Files section is closed for uploads.

[biofuel] University of Georgia heats campus buildings with chicken fat
http://enn.com/news/wire-stories/2002/02/02082002/ap_46348.asp - 2/8/2002 - ENN.com University of Georgia heats campus buildings with chicken fat Friday, February 08, 2002 By Associated Press ATHENS, Ga. - At the University of Georgia, home to thousands of students raised on Southern fried chicken, chicken fat is being put to an unusual use: heating the campus. Officials say it's cheap, it's safe, and it doesn't make the town smell like a KFC. Chicken fat, restaurant grease, and similar so-called biofuels could become a good alternative to fuel oil, Georgia scientists say. In tests over the last few weeks, the Department of Biological and Agricultural Engineering has used giant steam boilers - converted to burn animal fats - to heat water and buildings on campus. Tom Adams, the department's outreach coordinator, said the fuel is safer for people and the environment than burning coal and oil, and no one has complained about odor. The university spent about $30,000 to retrofit one of its big steam boilers so that it could burn animal fats and oils as well as natural gas or fuel oil. The campus' main boiler burns coal, but the others, including the retrofitted one, kick in to meet increased demand in cold weather. In tests that run several hours each day, the scientists have burned various mixes of petroleum and animal oils - sometimes up to 100 percent chicken fat, pork fat, beef tallow, or other greases. The fats give about 90 percent of the heat of fuel oil, Adams said, and the resulting air emissions are comparatively low in sulfur and other pollutants. The project, funded by the Georgia-based U.S. Poultry & Egg Association and the Fats and Protein Research Foundation in Illinois, also will test the potential of animal fat in other applications, such as truck and auto engines. "We've only scratched the surface," said Bob Synk, a consulting engineer on the project. The nation's dependence on foreign oil is increasingly seen as a problem, Synk said, and the U.S. energy plan calls for alternative fuel sources to supply up to 20 percent of energy needs within two decades. The country already produces about 11 billion pounds of fat a year from poultry, pork, and beef, with the poultry industry alone producing some 2 million pounds of chicken fat a week, Adams said.

[biofuel] Kentucky eyes biodiesel rule
http://www.etrucker.com/apps/news/article.asp?id=13874 e T r u c k e r - News Kentucky eyes biodiesel rule By Sean Kelley The Kentucky legislature is considering a bill that would require all diesel sold in the state to contain 2 percent biodiesel, a fuel derived from food-based waste oils or soybeans. If passed, the bill would require diesel sold in the state after July 1, 2003, to contain at least 2 percent of the fuel. The Kentucky Motor Transport Association is fighting the measure. "We are vehemently opposed to it," said KMTA President Ned Sheehy. "It's a cost driver. It's no less than an additional 3 cents a gallon." Sheehy said the law could encourage commercial drivers to avoid buying fuel in the state, hurting the local economy and the state's truck stops. "We would become a bypass state," he said. "Truckers would make sure they fill up before they come through Kentucky."

[biofuels-biz] Kentucky eyes biodiesel rule
http://www.etrucker.com/apps/news/article.asp?id=13874 e T r u c k e r - News Kentucky eyes biodiesel rule By Sean Kelley The Kentucky legislature is considering a bill that would require all diesel sold in the state to contain 2 percent biodiesel, a fuel derived from food-based waste oils or soybeans. If passed, the bill would require diesel sold in the state after July 1, 2003, to contain at least 2 percent of the fuel. The Kentucky Motor Transport Association is fighting the measure. "We are vehemently opposed to it," said KMTA President Ned Sheehy. "It's a cost driver. It's no less than an additional 3 cents a gallon." Sheehy said the law could encourage commercial drivers to avoid buying fuel in the state, hurting the local economy and the state's truck stops. "We would become a bypass state," he said. "Truckers would make sure they fill up before they come through Kentucky." KMTA supports a national standard but says a statewide mandate would create an unstable fuel situation similar to California, where the state mandates a lower-sulfur fuel, Sheehy said.

[biofuels-biz] Biodiesel plant sites considered
http://www.stjoenews-press.com/Main.asp?SectionID=81&SubSectionID=272&; ArticleID=24821 St. Joseph News-Press Biodiesel plant sites considered By SUSAN MIRES [EMAIL PROTECTED] At least three communities in the area are potential sites for biodiesel refineries. Representatives of Zambrana Engineering of St. Louis will visit St. Joseph in the next few weeks to evaluate the potential for a plant, said Lynn Parman of the St. Joseph Area Chamber of Commerce. Biodiesel is gaining attention as an alternative fuel made from soybeans and other plant and animal products. Zambrana is considering building several plants in Missouri. "They're interested in St. Joseph because of the existing industry," Ms. Parman said. "They want to partner with companies that have byproducts that can be made into biodiesel." Zambrana formed another company, North American Biorefinery Resources, to convert crops and animal wastes into energy. The business also is considering Bethany, Mo., as a potential location for a plant and held an informational meeting there in January. In Doniphan County, officials are working to attract a biodiesel facility. A public meeting will be held in Wathena, Kan., on Tuesday to gauge community support for the project. "We hope to see what the interest is, gather our thoughts and go from there," said Galen Weiland, economic development coordinator for the county. The meeting begins at 7 p.m. at the Wathena Community Building. Speakers from Kansas State Research and Extension will explain the basics of soydiesel production. Melissa Younggren of the Kansas Department of Commerce and Housing and Gail Murphy of Equity Financial Resources will talk about commercial and financial aspects of biodiesel projects. An industry that uses raw agriculture products is a good fit for the region, Mr. Weiland said. "We absolutely want to put a biorefinery right here in Doniphan County," he said. Soybean farmers have promoted biodiesel as an ecologically safe alternative fuel. The fuel is used by metro bus systems in St. Louis and Kansas City, as well as in buses at Northwest Missouri State University. "As we build the market, we see the need to build a production plant in the state," said Jessica Callow of the Missouri Soybean Association. The group expects demand to reach 4 million gallons by next year. U.S. Sen. Kit Bond, R-Mo., recently announced that if a farmer-owned biodiesel plant is built in the state, it would most likely be located in Mexico, Mo. A bill has been introduced in the Missouri Senate to give grants to qualified biodiesel producers.

[biofuel] Diesel never smelled like this
http://www.denverpost.com/Stories/0,1002,53%257E385631,00.html Denver Post.com - Diesel never smelled like this Biodiesel fuel nontoxic, veggie By Erin Emery Denver Post Southern Colorado Bureau Thursday, February 07, 2002 - PETERSON AIR FORCE BASE - A ferry from San Francisco to Alcatraz, U.S. Postal Service trucks in Manhattan and noncombat vehicles at Peterson Air Force Base are all powered by it. Biodiesel. It is a renewable, nontoxic diesel fuel that is made from vegetable products such as soybean oil and canola oil, along with animal fats and even recycled cooking grease from the neighborhood McDonald's. "It smells like your kitchen rather than your garage." said Gene Gebolys, president of World Energy Alternatives, the nation's largest biodiesel provider. Snowplows, pickup trucks and refueling vehicles that transport jet fuel to airplanes on the flight line at Peterson have since October been using a product called B-20, which is 20 percent biodiesel and 80 percent diesel. "It's been a success for us so far," said Master Sgt. Mark Trolio, chief fuels operator for Air Force Space Command. "Our vehicles are smoking less, and they are starting smoothly." Biodiesel doesn't have to be mixed with regular diesel for top performance, advocates say, but uncut biodiesel is mostly used in warmer climates. Biodiesel is the fastest-growing alternative energy in the United States. More than 150 public and private commercial fleets across the United States are using it because it has tremendous environmental benefits, it reduces the nation's reliance on foreign oil and vehicles don't have to be retrofitted for it. According to research commissioned by the National Renewable Energy Laboratory, operated by the U.S. Department of Energy, vehicles that burn biodiesel have cleaner emissions. In fact, biodiesel reduces cancer risk over diesel vehicle emissions by as much as 94 percent for 100 percent biodiesel and 27 percent with B-20. It's been called everything from "veggie power" to the "green" fuel for its environmental advantages, but bio-diesel is attracting a lot of attention primarily because companies don't have to spend money to retrofit their fleets, and vehicle performance doesn't suffer. "This is the easiest (alternative fuel) you can go to," Trolio said. "You can convert to biodiesel by emptying the fuel tank. All you have to do is make sure the tank is completely empty. It's a program that is so simple to get into. It's a wave, and we're ahead of that wave. Clean air - that's the biggest benefit to me. Who would not like cleaner air?" The drawback to biodiesel: It costs about 12 cents to 15 cents more a gallon than fossil fuels. Nevertheless, six U.S. cities already have biodiesel for sale at the pump, though most biodiesel is sold to fleets operated by companies or governments. The technology has been around since 1895, when Rudolf Diesel used vegetable oil to power an engine. It has only been in the last decade that economic and agricultural conditions have ignited interest in biodiesel, which could displace 2 percent of the nation's petroleum at full production capacity, Gebolys said. As a response to mad-cow disease in Europe, farmers discontinued the practice of feeding animal content back to animals. When cattle were allowed to revert to vegetarianism, there was an increased demand for soybeans but not soybean oil, creating a glut of oil and a plunge in vegetable oil prices. The government offers subsidies to people who buy biodiesel to offset losses to farmers. "Biodiesel is not just for agriculture anymore," Gebolys said. "About once every 10 years, we get a strong reminder of just how dependent we are on foreign oil and why we shouldn't be. We need to find new uses for our agricultural oil excess, and we need to find new sources of domestic clean energy. So it seems pretty clear to us that we can play a pretty important role."

[biofuel] Re: ethanol distillation
Okay, so solar stills are available, but do not produce a very high ethanol concentration with distillation. What about using solar energy to preheat your solution before it reaches a regular still. If you could preheat with solar power, less energy would need to be input it to the final distillation processes.

[biofuels-biz] Generally Stalled Motors
Generally Stalled Motors General Motors Corp. is not doing nearly enough to improve the fuel economy of its vehicles, according to a report released yesterday. That might not seem like news, but the organization that released the report, the Boston-based Coalition for Environmentally Responsible Economies, has been consulting with GM for almost 10 years and has been praised by the company in the past for being industry-savvy and reasonable in its expectations. The report notes that although GM has made some environmental progress by improving fuel efficiency in certain vehicles and reducing pollution at its factories, those gains have been offset by the rise in popularity of highly fuel-inefficient sport utility vehicles. The report comes at a time when the Bush administration and Congress are considering toughening the federal Corporate Average Fuel Economy standards.

[biofuel] California Plans Cuts in Vehicle CO2 Emissions
http://ens-news.com/ens/feb2002/2002L-02-01-06.html Environment News Service: California Plans Cuts in Vehicle CO2 Emissions By Cat Lazaroff SACRAMENTO, California, February 1, 2002 (ENS) - By the narrowest of margins, the California State Assembly has approved a bill that could create the nation's first restrictions on carbon dioxide emissions from automobile tailpipes. The bill directs the California Air Resources Board to adopt regulations that reduce the greenhouse gas pollution emitted by passenger vehicles. Vehicle emissions account for 58 percent of the greenhouse gas pollution, compared to 31 percent for the nation as a whole (Photo courtesy National Renewable Energy Laboratory) The California Assembly voted 42-24 along party lines to pass AB 1058 by Democratic Assembly member Fran Pavley. Forty-one votes were required to pass the bill. If the measure becomes law, state regulators will draft rules aimed at achieving "the maximum feasible reduction" of carbon dioxide emitted by California's passenger vehicles and light duty trucks, including sport utility vehicles. The regulations would need to be in place by January 2004, but auto manufacturers would be given flexibility in deciding how to achieve the new standards. The Board would be required to provide a report about the proposed program to the California Legislature by 2003, and the Legislature would then have one year to review the regulations. "This bill will give us the opportunity to protect California's economy, public health and the environment from the potentially devastating effects of global warming," said Assemblymember Pavley. "The bill will also allow California to greatly affect the outcome of the world's global warming crisis." California Assemblymember Fran Pavley, author of the bill targeting vehicle CO2 emissions (Photo courtesy California Assembly) "Global warming is the most urgent environmental problem we face today," Pavley added. "According to a consensus of the world's top scientists, global warming will increase extreme weather conditions and will potentially devastate many of the critical economic drivers in the state, including the agricultural, fishing, timber, real estate and insurance industries." The bill was cosponsored by two conservation groups, the Natural Resources Defense Council (NRDC) and the Bluewater Network. The Democratically controlled California Senate took up the bill today, and is expected to pass it as well. "California has to take the lead in addressing climate change because we are a significant part of the problem and because the White House and Congress have dropped the ball," said Ann Notthoff, California advocacy director for NRDC. Carbon dioxide and other emissions from cars and light trucks are responsible for one third of statewide climate change pollution, Notthoff noted. "Climate change is a global problem, but its effects will be felt locally. Rising temperatures will increase summer smog and a smaller Sierra snowpack would cut water supplies in a state already thirsty for water," Notthoff explained. "California's 22.6 million cars and light trucks belch 142 million tons of carbon dioxide into the atmosphere each year. California cannot solve climate change alone, but we can reduce our contribution to the problem and make ourselves a model for the rest of the world." California has long been a leader in combatting vehicle emissions, passing regulations that encouraged sales of emission free vehicles like the EV1, an electric car (Photo courtesy General Motors) Under a provision of the federal Clean Air Act, if California adopts AB 1058, other states will be able to follow suit, matching the new emissions limits with laws of their own. The bill has the support of a broad coalition of individuals and organizations, including Environmental Entrepreneurs (E2), a group of Silicon Valley business leaders that took an active role in meeting with legislators and galvanizing the business community to back the bill. "As business leaders, we recognize that immediate action must be taken to preserve the economic and natural resources that our state's businesses and residents depend and thrive on," said Bob Epstein, founder of E2. "The long term economic benefits of this bill stretch well beyond climate change protection. In fact, a recent study by the National Academy of Sciences concluded that carbon dioxide emissions from personal vehicles could be reduced by 30 to 40 percent by using readily available technologies that will save consumers thousands of dollars at the pump." Local governments - including Los Angeles, San Francisco and San Jose - have also expressed support for the bill, as have a number of public health groups. "This is a huge victory for the environment, air quality, and public health. It's also a win for motorists who will save on their gas costs," said Russell Long, executive director of Bluewater Net
