thermometer It's not a very common problem, but it happens. Straight vegetable oil More about methanol GC tests cost thousands, but we got it for nothing via a biofuels company we were helping. Corn is considered as the main source of ethanol-based biofuel. These usually involve mixing methanol with sodium hydroxide (also known as caustic soda or lye), and pouring the resulting mixture into vegetable oil. Most likely it'll be fine. Getting rid of it takes from a few hours for low doses to a day or two for higher doses. Or it might need more than three times as much, 66 grams, 17 teaspoonsful, or maybe more, and even then it'll only kill you if you can't reach a doctor within a day or two, and maybe it still won't kill you. duct tape Biodiesel production: a review - ScienceDirect Start with the process, NOT with the processor. Filtering WVO 2 funnels to fit the HDPE container, one for methanol, the other for lye What's left at the bottom is re-settled. Dissolve 1 gm of lye (KOH or NaOH) in 1 litre of distilled water to make 0.1% w/v lye solution (weight-to-volume). PDF Production of biodiesel from sunflower oil and ethanol by base In fact they're common enough household chemicals. The unit costs might seem quite high, but since you'll only be needing small amounts at first it's worth the price to eliminate the risk and confusion of poor-quality chemicals spoiling your results. One is settled, two are settling, and one is being filled. "Methanol is a fixed-carbon nutrient source for plants." Food or fuel? SP95-E10 (Sans Plomb 95 Octane, Ethanol 10% = Lead Free 95 Octane containing 10% of Ethanol) is already being sold throughout France. Relief can only be claimed by the qualified claimant. Recommendations, and much more, here. Why can't I start with the Foolproof method? We used sodium lye drain-cleaner (NaOH, sodium hydroxide) bought in small plastic containers at a local hardware store, not always very fresh. Glycerine is hygroscopic enough to pull moisture out as it settles down so you don't have to heat or boil the oil to dry it. Moving on to bigger things We pump both glycerine cocktail and oil at the same time into a separate container. Contrary to rumour, "phenol red", sold by pool supply stores, won't work for titrating WVO, its pH range isn't broad enough. I have 4 WVO barrels. Settle for three hours or more. See The SVO vs biodiesel argument Next: Make your own biodiesel -- Page 2 Learn More About How To Make Biodiesel Here! Take the number of millilitres of 0.1% lye solution you used and add the basic amount of lye needed to process fresh oil -- 3.5 grams for NaOH or 4.9 grams for (pure) KOH. This is an extremely caustic chemical. See The SVO vs biodiesel argument This was just an investigative project for us when we made our first biodiesel more than seven years ago in Hong Kong. What we do is use at least 10/90 weight ratio: 10kg of glycerine for 90kg of waste oil. But the centrifuged fuel didn't come close to the standards requirements. The biodiesel should be ready for instant consumption if it's clear and bright and without sediments. 1. Washing Centrifuges Most major European vehicle manufacturers now provide vehicle warranties covering the use of pure biodiesel -- though that might not be just any biodiesel. He was away for about 10 days and when he came back he called to tell me that he couldn't distinguish the oil from the top half of an unfiltered cubie from his filtered oil. We had difficulty finding pure methanol in Hong Kong, and eventually paid the very high price of US$10 per litre for 5 litres from a wholesale chemical supply company. Here's another way, from Aleks Kac -- it uses less energy and doesn't risk forming more Free Fatty Acids (see below) by overheating. Lye is very hygroscopic, it absorbs moisture from the air; summer humidity in Hong Kong is usually about 80% at 30 deg C or more, and the lye rapidly got wet, making it less effective. What is the cetane rating of methanol? The lethal dose of methanol for humans is not known for certain. All methanol containers should be kept tightly closed anyway to prevent water absorption from the air. Where industrial gas oil is marked at a duty-paid terminal the assumption will be that theres no biodiesel component, as theres no (current) commercial reason why biodiesel should be present. (See More about lye.) Glycerine is hygroscopic enough to pull moisture out as it settles down so you don't have to heat or boil the oil to dry it. The "energy" does you no good if your particular thermodynamic cycle can't take advantage of it. When it's clear (not colourless but translucent) it's dry and ready to use. The "bottoms" are resettled the same way, first in 18-litre metal cans. Most people use a pH meter or phenolphthalein solution, and that's what we recommend. If it's still not crackling by 60-65 deg C (140-149 deg F) there should be no need to dewater it. Most of the equipment was rough and improvised. See: Biodiesel and your vehicle -- Compatability: Rubber. And it works. (See above, Mixing the methoxide.) I adjust the inlet openings to regulate the mixing. Using biodiesel He was away for about 10 days and when he came back he called to tell me that he couldn't distinguish the oil from the top half of an unfiltered cubie from his filtered oil. Add 3.5 grams (0.02 oz) of lye. The biorefinery has helped Algenol exceed its milestone of 9,000 gallons of ethanol per acre per year at peak productivity, with an additional 1,100 gallons per acre per year of hydrocarbon fuels. See Removing the water, below. For test batches, some suppliers sell small quantities as well as bulk, try chemicals suppliers. Please read this whole section right to the end. We'd also bought 10 litres of the cheapest new cooking oil we could find -- we don't know what kind of oil it was, the tins only said "Cooking Oil" -- and we used this for our first experiment. The HSE has published advice on the hazards of producing biodiesel at home. (Not advised, it's dangerous to use sparking electric motors such as those in drills for processing with open containers. We use an ordinary 1/2 hp clear water pump with two inlet pipes to suck in glycerine and wvo. The reaction started immediately, the mixture rapidly transforming into a clear, golden liquid. Full document -- Acrobat file, 104kb Guaranteed trouble-free See also: Keith checks the pH of the waste oil. See Washing No titration? two 2-litre PET bottles for washing For instance, different blenders and mini-processors have different shapes and different rates of agitation, and the processing time required for good process completion can vary accordingly. Although I cannot get complete conversions in these cases, drying the oil by heating and vacuum has allowed me to do this and still avoid problems with soap formation. More likely you just need a little more practice, especially with accurate measurements. Mix for 20-30 minutes, or longer. If youre approved for deferment, you should set-off the relief against your normal excise duty liability in the Duty Claimed section of form HO10. 2 funnels to fit the HDPE container, one for methanol, the other for lye See Biodiesel and your vehicle Then try a small 1-litre test batch first. Biodiesel in gasoline engines But it definitely can kill you. It might have been only 1 in more than a thousand cases because most cases weren't reported. Subject to the deferment conditions contained in Motor and heating fuels general information and accounting for Excise Duty and VAT (Excise Notice 179), producers of fuel substitutes, biodiesel, bioethanol and their blends may defer their excise duty. As soon as the process is completed, pour the mixture from the blender or the mini-processor into the 2-litre PET bottle for settling and screw on the lid tightly. What's the most energy-efficient crop source for ethanol? | Grist In any other case, youll need to make a claim in writing to the MORC. The rest stays in the biodiesel and is washed out when you wash the fuel, mostly with the first wash. Reclaiming it costs more energy than it's worth -- the first wash-water probably won't contain more than 5-6% methanol (as well as a little sodium or potassium and some soap). It's also very corrosive. -- Chris Tan If you disagree with a decision made by one of our officers you may be able to have a review or to appeal to an independent tribunal. No children or pets allowed. See Washing Yet people have survived doses of 10 times as much -- a quarter of a litre, half a pint -- without any permanent harm. At worst the car simply stops, starved of fuel. 9. Nitrogen Oxide emissions Where do I start? Higher viscosity is not the only problem with using vegetable oil as fuel. These are dangerous chemicals -- treat them with respect! The methanol in unwashed biodiesel doesn't "make a great fuel anyway". Pour off the biodiesel from the top of the container. Only a supplied-air system will do (SCBA -- Self-Contained Breathing Apparatus). Production of Fuel Ethanol - Biodiesel Project Biofuels Proceed with processing as above, maintain temperature at 55 deg C (130 deg F), process for one hour or longer. The time it takes will depend on the gallons per minute rate of your pump, which is not the same for viscous oil, so measure and compute the time required for one or two cycles. Algenol has an algae strain that can produce ethanol directly, and the system can then convert remaining biomass into hydrocarbon fuels such as biodiesel, gasoline, and jet fuel. See More about lye.) I allow the WVO to settle in cubies for a week. This is how it works (comment from a Biofuel list member): Authorities advise that swallowing up to 1.3 grams or 1.7 ml of methanol or inhaling methanol vapour concentrations below 200 ppm should be harmless for most people. See: Phenolphthalein Judging by appearances With used oil, titration with NaOH to check the acid content has become the de-facto comparative measure of different oils -- whether they use NaOH or KOH in their processing, when describing oils most biodiesel brewers refer to however many millilitres of NaOH solution it needed to titrate the oil. Palm oil, coconut oil, tallow and lard are also summer fuels, with high melting points: they start to gel and set at quite high temperatures. -- Chris Tan If there's water in it it will start to "snap, crackle and pop" by 50 deg C (120 deg F) or so. Wear proper protective gloves, apron, and eye protection and do not inhale any vapours. -- Joe Street, Biofuel mailing list, July 2006 However, there's a lot to be said for the GREAT feeling of independence you'll get from making your own fuel. Lye (both NaOH and KOH) is extremely caustic -- don't get it on your skin or in your eyes, don't breathe any fumes, keep the whole process away from food, and right away from children. Mixed with methanol they form methoxide. Biodiesel in Hong Kong "I am a pipe welder who knew nothing about chemistry but I have learned a lot from this website. In all cases, we may ask you to provide evidence to substantiate your claim. But rubber parts in diesel engine fuel systems have been rare or non-existent since the early 1980s -- it seldom happens, and when it does happen it's not catastrophic, you have plenty of warning and it's easily fixed. Using a mini-processor. Many thousands of biodiesel homebrewers worldwide have been using it for years without serious mishap. See: Biodiesel and your vehicle -- Compatability: Rubber. Biofuel list member Joe Street adds: (See next.) We've had a number of reports that centrifuges give poor results compared with normal settling, and especially compared with washing -- washing centrifuged fuel has yielded very soapy wash-water, so obviously the centrifuging didn't work very well. A significant share of the feedstock for domestically produced biodiesel (rapeseed, soybean) came from import together with vegetable oil (mainly palm oil) is also used. Use HDPE (High-Density Polyethylene), glass, enamel or stainless steel containers for methoxide. We do it much the same way, settling the WVO first in the 18-litre metal cans it's supplied in here, then pouring it from the top. Make your own biodiesel - page 2: Journey to Forever FOOLPROOF biodiesel process Replace the bung and screw on the cap tightly. If you burn/maim/blind/kill yourself or anyone else, that will make us truly sad, but not liable -- it's nobody's responsibility but your own. Many people filter their WVO before making biodiesel, but filtering takes time and energy, and there's really no need to filter it. Few solutions are ideal, in terms of Raoult's law, and in used vegetable oil, there is no way to know what solutes are in the oil. The host oil means whatever oil they are added to. According to US EPA studies methyl esters biodiesel is less toxic than table salt and more biodegradable than sugar. (It's toxic mainly to humans and monkeys.) Chemicals for processing waste oil Youll need to register and account for the duty due on any products set aside or delivered for use as motor fuel if you: produce 2,500 litres or more of biofuels a year, use 2,500 litres or more of biofuels as motor fuel on which duty has not been paid. Phenolphthalein lasts about a year. duct tape Acrobat file, 2.1Mb: You don't need a centrifuge. The main danger is when the methanol is hot -- when it's cold or at "room temperature" it fumes very little if at all and it's easily avoided, just keep it at arm's length whenever you open the container. Testing should always be done when there are changes in the recipe and either or both of the: The following table is a guideline to the minimum frequency and level of tests HMRC expects. NOTE: This is a standard World Wide Web document, which means it's hyperlinked. And we don't use open containers for processing now, and neither should you (see Safety, see Processors) -- and mix the methanol in closed containers too. Form EX55 can also be used to claim back duty paid on gas oil used to generate electricity. Phenolphthalein lasts about a year. Read on! With care and experience the production rate improves. Next: Make your own biodiesel -- Page 2 Excise duty is not chargeable if you set aside or use biofuel: See section 5 regarding the mixing of biodiesel and bioblend with rebated heavy oil. After settling, carefully decant the top layer of biodiesel into a clean jar or PET bottle, taking care not to get any of the glycerine layer mixed up with the biodiesel. Three of these in a series are estimated to produce 5 MMgy or more of biodiesel from DCO, also produced on-site. (See next.) It's safe if you're careful and sensible. Do diesels have a future? Find a source of oil that titrates at about 2.5 ml of 0.1% NaOH solution or less, not more than 3.5 ml. Pump the oil out from the top, leave the bottom 90% for removal later and re-settling. Washing Biodiesel and your vehicle Use for wash water - methanol. Moving on to bigger things For your first test batches you need oil with the standard acid content, so avoid these oils too. Results will vary depending upon the nature of the water-soluble impurities in the oil. Top quality In which case there's no need for mixes, you can just use 100% SVO. If it's poor quality oil with a high titration level, heat it first, as in de-watering (above), and then let it settle. We've had a number of reports that centrifuges give poor results compared with normal settling, and especially compared with washing -- washing centrifuged fuel has yielded very soapy wash-water, so obviously the centrifuging didn't work very well. Keep on carefully adding the lye solution until the mixture just starts to turn pink (magenta) and stays that way for 15 seconds. Keep on carefully adding the lye solution until the mixture just starts to turn pink (magenta) and stays that way for 15 seconds. Biofuels: Ethanol and Biodiesel | Renewable Energy Technologies - Books (A cubie is the 4.5 gal (17.7L) plastic container that veg oil is delivered to restaurants in.) -- From "Agriculture and Methanol", Chapter 7, Methanol Production and Use, ed. Using biodiesel Note however that the authors of Methanol Production and Use caution that the application of methanol to crops still requires further study before we all "rush out to spray methanol". Our first titration took 6 ml of 0.1% NaOH solution (not very good oil), so we used 6 + 3.5 = 9.5 grams of NaOH per litre of oil. If in collection you keep ahead of your processing rate, oil has a chance to settle. There are two main categories of biofuel; biodiesel and bio-alcohol. Get some small glass jars and keep samples of all your batches, clearly labelled and cross-referenced to the notes in your journal. Probably they need a bigger processor, or two processors in parallel, rather than trying to make gravity hurry. If you're careful and sensible and treat it with caution it won't harm you either. Moving on to bigger things If I can understand this anyone can." See Safety (I am also very careful with my caustic and methanol.) (Wooden chopsticks make good stirrers for titration.) The normal background-level quantities of methanol in humans are eliminated and replenished all the time as a matter of course. Use phenolphthalein indicator, specifically 1% phenolphthalein solution (1.0 w/v %) with 95% ethanol. If youre unhappy with HMRCs service, contact the person or office you have been dealing with. Other uses Fact: Human susceptibility to the acute effects of methanol intoxication is extremely variable. It is absorbed easily through the skin and there is no means of elimination from the body, so levels of methanol dissolved in the blood accumulate." NOTE: Beginners should avoid poor-quality oil like this for their first test-batches with used oil. Here's what Biofuel mailing list member Dale Scroggins says about water removal: Pannir Selvam, Technology Center, Department of Chemical Engineering, Universidade Federal do Rio Grande do Norte (UFRN), Brazil, Biofuel mailing list, 15 Apr 2007 The US biodiesel standard specifies a cetane number higher than 47, the EU standard specifies higher than 51. Making Biodiesel Fuel at Home - NewEarth Media I figure I have replaced over the last couple of years over 100 thousand gallons of petroleum diesel with biodiesel derived from waste cooking oil collected in New England and New York City. Boiling off the water is more difficult than it appears on the surface. I have found that oil that has been sitting for several weeks is very dry if carefully decanted. Keep your processing fine-tuned by making test batches and using the quality tests. This address is not for general enquiries. Check that the blender seals are in good order. Lye is sold in supermarkets and hardware stores as a drain-cleaner, there's probably a can of it under the sink in most households. When we make our appointment well tell you: how long we think that the visit will take. Simple, safe, efficient biodiesel processors you can build cheaply and easily Suspended droplets that cannot be coalesced and water in solution are more problematic. For fire risks, see Hazards The Hydrocarbon Oil, Biofuels and Other Fuel Substitutes (Determination of Composition of a Substance and Miscellaneous Amendments) Regulations 2008 allow relief, in certain circumstances, from duty on bioblend used for electricity generation. Use low-titration oil for your first used oil test batches, move on to higher titration levels and different kinds of oil as you gain experience. It has to be pure NaOH. Glycerine pre-wash 9.2 The Reaction of Biodiesel: Transesterification Low levels of release would not be expected to result in adverse environmental effects. into biodiesel, with the dried remainder further reprocessed to create ethanol. Most likely it'll be fine. Duda's Alternative Energy Store supplies phenolphthalein solution in convenient 18 ml dropper bottles, enough for about 180 titrations, buy online: http://dudadiesel.com/ It's not something nature's simply never heard of before and has no way of handling and neither do you, unlike too many of the 100,000-odd "new" chemicals now in use which aren't readily biodegradable and do accumulate, and spread, and keep being implicated in cancer clusters and bizarre sexual distortions of frogs and so on and on and on. This mixture is sodium methoxide, a powerful corrosive base -- take full safety precautions when working with sodium methoxide, have a source of running water handy, along with a bottle of vinegar -- quench any splashes on the skin with vinegar, thern rinse thoroughly with running water.
