Yes I adjust the inlet openings to regulate the mixing. Then, check the acid content, by titration. 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. Sugars are fermented into ethanol and lignin is recovered and used to produce energy to power the process. It's essential to titrate the oil to find out how much FFA it contains so you can calculate exactly how much extra lye will be required to neutralise it. The cetane rating of methanol is only 3, very low. Most of the equipment was rough and improvised. Laboratory analysis will be used to settle any disputes or doubts about the biofuel content and can be conducted at the duty suspended premises to which the fuel is returned or at an independent laboratory. Accurate measurements The high-speed diesel engines in cars and trucks are designed to use fuels with cetane numbers of about 50. Youre exempt and do not need to register and account for duty if in the last 12 months youve produced or used, or expect to produce or use in the next 12 months, less than 2,500 litres of either any: However, there are simple record keeping requirements, which are described in paragraph 4.10.1. We have laboratory test results of "finished" biodiesel made here in Japan in a $70,000 commercial processor. If in collection you keep ahead of your processing rate, oil has a chance to settle. Bioethanol is a liquid fuel consisting of ethanol produced from biomass that is capable of being used for the same purposes as light oil. My father came up with the idea that you can use the glycerine cocktail to dry your waste vegetable oil. Test first for water content -- heat half a litre or so of the oil in a saucepan on the stove and monitor the temperature with a thermometer. Unit costs from these sources might be 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. To tell HMRC, email: morcexciseeast@hmrc.gov.uk. Check the quality of your biodiesel with these quality tests. Wear proper protective gloves, apron, and eye protection and do not inhale any vapours. There are at least three ways to run a diesel engine on vegetable oil: Don't do it -- life is easier with longer settling times, for the WVO, for the by-product to separate after processing, and for the wash-water to separate, especially after the final wash. The main points are as follows: Biodiesel is produced commercially and can be bought from some petrol stations. Low levels of release would not be expected to result in adverse environmental effects. As water is removed, more heat or lower pressure will be required to remove more water. See "Simple 5-gallon processor" for a much better way.) All the various processing methods use averages and approximations because processors and conditions vary so widely. And it works. Start with fresh unused oil, NOT with waste vegetable oil (WVO), that also comes later. You cannot afford to cut corners. Wear proper protective gloves, apron, and eye protection and do not inhale any vapours. The methoxide is mixed like this -- Methoxide the easy way, which also happens to be the safe way. Meanwhile we'd warmed the 10 litres of new oil in a 20-litre steel oil drum to about 40 deg C (104 deg F) to thin it so it mixed better (55 deg C, 131 deg F, is a better processing temperature). That's from a British website trying to sell Straight Vegetable Oil (SVO) solvent additives by frightening people with the alleged perils of biodiesel. The details which must be recorded by the receiving warehouse keeper or at the remote marking premises are set out in paragraphs 5.8.4 and 5.8.5 of Motor and heating fuels general information and accounting for Excise Duty and VAT (Excise Notice 179). Freshly made biodiesel, 20 minutes after processing I estimate that oil at 55-60 deg C can contain as much as 10,000 PPM (that's 1%) water. Support is available for UK biofuels through the Renewable Transport Fuel Obligation (RTFO). Here's what Biofuel mailing list member Dale Scroggins says about water removal: Water in vegetable oil can exist as free water, which will eventually settle to the bottom of a vessel; as suspended droplets, which may settle if the oil is heated, or the droplets are coalesced; and as water in solution with other impurities in the oil. Biofuels supplies and suppliers Shake the container to check it hasn't absorbed moisture and coagulated into a useless mass, and make sure to keep it airtight. Wear proper protective gloves, apron, and eye protection and do not inhale any vapours. Question: Just how dangerous is methanol? If you issue special equipment or protective clothing to your staff when theyre undertaking activities such as handling, inspecting or sampling biodiesel then you must provide similar clothing and equipment to us when we undertake the same activities. Biodiesel in Hong Kong Here's another way, from Aleks Kac -- it uses less energy and doesn't risk forming more Free Fatty Acids (see below) by overheating. Out of 1,601 methanol poisonings reported in the US in 1987 the death rate was 0.375%, or 1 in 267 cases. Chemicals needed Melting point of ethanol is -114.1 o C, and the boiling point is 78.5 o C. Ethanol is polar due to the electronegativity difference between the oxygen and hydrogen in the . Don't use a gas burner for this or any other stage of the biodiesel creation process. It may be worth contacting a licensed or authorised denaturer with your proposals to make sure that your formulation can be produced. Thousands of ordinary people have done this without any other help, and so can you. How is methanol removed from biodiesel? Duda's also supplies a WVO Titration Kit, which includes a variety of syringes, beakers, all the titration chemicals and gloves: http://dudadiesel.com/ To view this licence, visit nationalarchives.gov.uk/doc/open-government-licence/version/3 or write to the Information Policy Team, The National Archives, Kew, London TW9 4DU, or email: psi@nationalarchives.gov.uk. Cheaper in the long-run 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. It's sensitive to light, store it in a cool, dark place. All equipment should be clean and dry. endstream endobj startxref Mixed with methanol they form methoxide. The standard specifications of petrol and diesel in the UK are British Standard (BS) versions of European Standards (EN): Up to 5% Ethanol in petrol is considered not to cause any compatibility issues with car fuel systems and there's no need to mark pumps to tell customers that the fuel maycontain biofuel. It fumed and got hot, and took about 15 minutes to mix. Thegovernment discouraged an early switch to E10 in the UK so that the number of incompatible vehicles can reduce further (through end-of-life). Probably they need a bigger processor, or two processors in parallel, rather than trying to make gravity hurry. (It's better to start with smaller one-litre test batches.) two 2-litre PET bottles for washing 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. Question: How much does it take to kill you? The longer oil is cooked and the higher the temperature, the poorer the quality will be, but the colour of used oil also depends on the food that's been cooked in it -- soy sauce and other sauces, sugar, food colourings can all make the oil darker, without affecting the quality and the FFA content. To put it all in some perspective, methanol is the main or only ingredient in barbecue fuel or fondue fuel, sold in supermarkets and chain stores as "stove fuel" and used at the dinner table. Yes, if you use a good system. With waste oil you have to use more lye to neutralise the FFAs. You can do it too it's proof that the step-by-step instructions you'll find here and Journey to Forever's backyard brewers' cheapo kitchen-sink quality tests will indeed guide you to a top-quality product that will make any diesel engine happy, and keep it that way. You don't have to convert the engine to run it on biodiesel, but you might need to make some adjustments and you should check a few things. We use an ordinary 1/2 hp clear water pump with two inlet pipes to suck in glycerine and wvo. But the large and rapidly growing worldwide band of biodiesel homebrewers don't mind that -- they make a supply every week or once a month and they soon get used to it. Anyway washing the fuel is easy. Joe Street's titrator 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). The drum has a bottom drain fitted with a 6"-high 3/4" standpipe (15cm-high x 1.9cm), which leaves any sediment on the bottom of the drum undisturbed. See Washing It's not just us who say so, it's largely the result of a collaborative effort over 10 years involving thousands of people worldwide -- it's what works. Don't use "open" reactors -- biodiesel processors should be closed to the atmosphere, with no fumes escaping. Find more information in Notice 203a: registered consignees. NaOH is cheaper to use. Again, people want to "speed up" the process by using a centrifuge instead of settling (or instead of washing, in some cases). All methanol containers should be kept tightly closed anyway to prevent water absorption from the air. 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. Biodiesel Information - Biodiesel process - Biofuel Systems If you don't have time to wait for the oil to settle, usually 1-2 weeks, it could be worth increasing the WVO supply and reserves to make the time. Fact: Methanol is a poisonous chemical that can blind you or kill you, and as well as drinking it you can absorb it through the skin and breathe in the fumes. Heat the oil to 60 deg C (140 deg F), maintain the temperature for 15 minutes and then pour the oil into a settling tank. 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. The glycerine will flow at a lower rate and the the inlet opening should be adjusted so that it finishes at the same time as the oil. Mix for 20-30 minutes, or longer. See instructions here. NOTE: Beginners should avoid poor-quality oil like this for their first test-batches with used oil. With waste oil you have to use more lye to neutralise the FFAs. FOOLPROOF biodiesel process Ethanol and biodiesel: dropping below the production cost of fossil See How the process works This was just an investigative project for us when we made our first biodiesel more than seven years ago in Hong Kong. See Biodiesel and your vehicle The Base fuel, FAME and Cold flow additives must all be carefully optimised. Safety. (See above, Mixing the methoxide.) Answer (1 of 3): You probably could use ethanol, but * methanol is cheaper in industrial quantities * the esters of methanol have a lower melting point than those of ethanol (fewer problems with the biodiesel gelling or solidifying at low temperatures) * methanol esters probably ignite more r. Duda's Alternative Energy Store supplies pure methanol in small quantities "for getting started", and in 55-gal drums, buy online: http://dudadiesel.com/ Phenolphthalein lasts about a year. Fact: There is no free methanol in washed biodiesel. This will prevent central assessments being raised on your record. Test batches with used oil There are two primary pathways to produce cellulosic ethanol: biochemical and thermochemical. You only need to enter your premises once for all your production of biofuels or fuel substitutes. 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. Water in the oil interferes with the lye catalyst, especially if you use too much lye, and you can end up with a batch of jelly. pH meters Biofuels supplies and suppliers Methanol can cause blindness and death. Quality testing When it just starts to turn pink and stays that way for 15 seconds it's reading pH 8.5, which is the measure you want. I pump WVO out of the settled barrel from the top 3/4. Methanol and Plants When mixed, the methoxide is again pumped into the (closed) biodiesel processor with the aquarium air-pump -- there's no exposure to fumes, and it's added slowly, which is optimal for the process and also for safety. As with filtering, if you want more production get a bigger processor, or run two processors in parallel, add more settling and washing tanks. Glycerine pre-wash Results will vary depending upon the nature of the water-soluble impurities in the oil. With poor-quality oils that have high titration levels do bracket tests as well. Environmental effects due to exposure to methanol are unlikely. Biofuels See also: We have laboratory test results of "finished" biodiesel made here in Japan in a $70,000 commercial processor.
