I am building a processor with a wash tank with over 400 u.s. gallon capacity and am using a bulk tank adgitator I purchased used from a dairy farm supplier.My adgit ator is aprox. 14 inches wide and 14 inches high.If your system is smaller just down size some.With an adgitator you can let it run as long as it takes to mix the biodiesel and water wash.

Why bring it up to 130C ? Did it need dewatering or was it just a precaution? A sample test in a saucepan brought up to temp would have confirmed it one way or the other. I have made BD using some really crappy WVO which titrated at 10gr/liter and washed it using a paint stirrer and it tunred out OK. The procesing temp is too high in your case.65C will boil off the methanol which goes vapour at about 64C. Your processing temp should not be over 55C (130F). Too high or too low will result in poor end product.( I know, I've done it) 2HP pump huh? Wow ! Bet that thing hums huh? Might be a bit too much for such a small amount though, although someone else will have to comment of that as I am not in the know on it.

I will admit, those little propane hand torches come in real handy, maybe I could find the connectors and hose to use the big bottle with the little torch.

[biofuel] Question - efficiency of sunlight conversion
I have a question that some of you might be able to shed some light on. As well as having an interest in biofuels, I also have an interest in Third World development issues and other technologies, including Solar energy collection and storage. So when trying to find an 'energy solution' for a remote village for example, there are a number of possible options. Of course, you have to ask, what problem are you looking to find a solution for? For the purposes of this post, I will assume that we are trying to provide electricity to power refrigerators, lighting, miscellaneous equipment such as telephones and computers (even remote villages can have satellite connections to the internet these days!). This would be a light load and not include industrial use nor electrical heating/cooking. So I will propose two solutions, both of which are used in various places: 1) Grow an oil crop, use it to power a diesel generator 2) Install photovoltaic solar panels and use a battery system to store the energy overnight Now I'm trying to get an understanding of the pros and cons of these two approaches, and which would be better for a particular location. The issues I have thought of so far are the following: -- Photovoltaics and batteries are expensive in terms of capital outlay, whereas biofuels are cheap to 'install'. Photovoltaic systems have a conversion efficiency of ~10% of the solar energy, whereas biofuels have a conversion efficiency of about 1% Photovoltaic systems require more specialist knowledge to maintain, whereas biofuels require less. Photovoltaics require low labour input once they are installed, whereas biofuels require planting, harvesting, processing etc.. Photovoltaic systems can store only small amounts of energy over short timescales, whereas you can store large quantities of oil for a long time Photovoltaics make less sense when sunshine levels are highly unpredictable, whereas biofuel crops are not significantly affected by a few gloomy days Photovoltaics require less land to install than oil crops, because of their higher conversion efficiency. -- I realise that this is an oversimplification of the issues, and I'm trying to gain a deeper understanding of the secondary issues. So my specific questions are: 1) What are the implications of manufacturing Solar collectors, batteries, electronic control equipment and so forth in terms of energy use, toxic materials (e.g. lead in batteries), sustainability? How does this compare with manufacturing a diesel generating system? 2) Biofuels are often produced from crops that are grown in an unsustainable manner. What are the effects on biodiversity of this? How can this be counteracted? Are there any comparable environmental issues in the manufacture of solar systems? 3) Do the levels of expertise required to install and maintain a solar system make it inappropriate for use in remote villages? 4) Am I correct in assuming that the best (cheapest over all) solution for a Diesel generator in such situations is to use SVO (straight vegetable oil) with a preheating system, rather than converting it to biodiesel? 5) What are the effects on electricity usage patterns for each type of supply? For example, if people know that their battery system can only store a fixed amount that won't be replenished until the next day, are they more efficiency conscious than if they know their supply won't be replenished until next year's harvest? My gut feeling is that due to the higher conversion efficiency of solar panels, these would make a better overall solution for providing electricity than growing biofuels, with less environmental impact overall. However the high capital cost may rule this solution out for smaller villages. (Of course if you are using the energy for transport, then biofuels are much better because the energy can easily be stored and transported over long timescales. But that is not what I'm interested in here). Does anyone have any other information, opinions, experience of these types of systems? Have I overlooked any significant arguments on either side? I may soon have an opportunity to visit a remote solar installation that is backed up with a Diesel generator (as far as I know using petrodiesel) so wish to find out as much as possible beforehand.

Hi Peggy, Do you have any reference or web links to the process? It would be another interesting area to look at. Hi Peter, Just got back. I think that Cambodia is a really good target. Since as you said there's no oil refinery there. My initial gut feeling was that BD can be developed in Vietnam also. But I have since found out that Vietname has just constructed an oil refinery and it should begin operational soon. I hope that your venture in Cambodia will be successful. Do keep us updated. God Bless, Caleb --- Peggy [EMAIL PROTECTED] wrote: - Hello Peter, It is possible to make fuel ethanol from discarded paper and food waste (non-dairy and no meat) making fuel ethanol another alternative to biodiesel as well. Peggy Hi Caleb ;; I agree with you 100% about used frying oil being a questionable feedstock. There simply isn't enough of it to make any significant business out of it, and it is spread out over a large geographic area. Yes, sure the backyard tinkeres can make a go of it. But as soon as you start to buy any significant quantites, the price will surely rise, plus you have significant collection costs. You can estimate the available quantity by trying to think about how much frying oil you personally use, then add in some extra to account for the fried donut or fried chicken that you ate at the restaurant. Then compare that to how much diesel you use. Then add in the diesel used for your electricity, all the transportation costs to bring your food to the supermarket, ect. For me I use about 100 times more diesel than frying oil. So then we could roughly estimate that if a city uses for example 1 million liters of diesel a month, there would be 10,000 liters of used frying oil. But only a small fraction could be recocovered (you couln't recover the used frying oil that I personally use, for example). My conclusion is that a very small number of people could make it work, but as soon as a few more people try, supplies will dry up. That's why biodiesel is irrelevant without an abundant feedstock. Please don't forget about all the people dying, being killed, destroyed lives in the middle east over oil wars. Then add in the huge cost in military hardware, all the lost productivity of the men figting instead of working, and I'm not so sure that the cost of diesel is lower than the cost of biodiesel made from palm oil. Yes Malasia is the world leader in palm oil plantations, so this would not interest you. But Cambodia has no oil plantation and no oil wells either. They are net importers of both commodities. So they are very interested in both possibilities. Yes please keep me infomed about the BioFuel conference in December. Best Regards, Peter G.

The industry is well established. There was a push for BioDiesel back during the 2002.

Though rising oil prices might actually reverse all that. Diesel prices in Malaysia is far too cheap. According to the latest prices, we're the second cheapest after brunei.

I have plans as you to perhaps develope a small biodiesel industry in Singapore based on used cooking oil. Still doing a lot of ground work at the momement. Singapore is moving towards euro IV emission standards, and biodiesel can help offset some of the cost of migrating to euro IV disels here.

Re: [biofuel] pump size
Pierre, Use what you tools you have and adjust your reaction time accordingly. If the manufacturer's specs are available to you, check the rated gph of the pump at 3' of head pressure. Then multiply that volume by ~60% due to reductions caused by pumping a fluid far more viscous than water, which is what the specs will probably refer to. Divide that volume by the volume in the reactor and you've got a very crude guestimate of the number of turnovers per hour in your reactor. To judge an appropriate reaction time, pull an exact amount of fluid (200 ml would suffice) out of the reaction stream every half-hour or hour after an arbitrary initial ~1 hour reaction period. Presuming that the contents of the reactor are kept homogenous from the pump flow, the volume of the glycerol cocktail that settles out of each sample will give you a fair gauge as to when your reaction completed. The suggestion would be to continue the reaction for ~1/2 hour beyond the point where your glyc cocktail volume stabilized.

Re: [biofuel] Re: pump size
L, The only problem you will have to be aware of is if you use NaOH as a catalyst as it may want to harden as it cools and this can be a problem in pumps and the lines. I have done away with the potential of this happening, after reading comments from Todd and G-Mark about isolating the pump and draining the lines once processing is complete. I have successfully done this with my unit and as an unexpected bonus it also provided me with a sample for quality testing while the main mix settles. You cannot rely upon a sample being pulled from the pump as being an accurate sampling. While the pump may be circulating fluid at what appears to be sufficient volume to achieve homogeneity, glycerol remains heavier than the esters and the pump is continually pulling off the bottom. The reality could easily be that you're pulling off a higher ratio of the glyc coctail via the pump sample than you might from a top or mid-range sample. The fuel portion should theoretically be similar, but the glyc to fuel ratios may be different.

Maybe the following can give you more ideas. http://www.undp.org/seed/energy/contents.html Biofuel will also open up the possibility to use it for transportation, work, water pumping, etc. Its labor input is not a negative, it is a positive, since it is local.

Photovoltaic systems can store only small amounts of energy over short timescales, whereas you can store large quantities of oil for a long time Photovoltaics make less sense when sunshine levels are highly unpredictable, whereas biofuel crops are not significantly affected by a few gloomy days Photovoltaics require less land to install than oil crops, because of their higher conversion efficiency. -- I realise that this is an oversimplification of the issues, and I'm trying to gain a deeper understanding of the secondary issues. So my specific questions are: 1) What are the implications of manufacturing Solar collectors, batteries, electronic control equipment and so forth in terms of energy use, toxic materials (e.g. lead in batteries), sustainability? How does this compare with manufacturing a diesel generating system? 2) Biofuels are often produced from crops that are grown in an unsustainable manner. What are the effects on biodiversity of this? How can this be counteracted? Are there any comparable environmental issues in the manufacture of solar systems? 3) Do the levels of expertise required to install and maintain a solar system make it inappropriate for use in remote villages? 4) Am I correct in assuming that the best (cheapest over all) solution for a Diesel generator in such situations is to use SVO (straight vegetable oil) with a preheating system, rather than converting it to biodiesel? 5) What are the effects on electricity usage patterns for each type of supply? For example, if people know that their battery system can only store a fixed amount that won't be replenished until the next day, are they more efficiency conscious than if they know their supply won't be replenished until next year's harvest? My gut feeling is that due to the higher conversion efficiency of solar panels, these would make a better overall solution for providing electricity than growing biofuels, with less environmental impact overall. However the high capital cost may rule this solution out for smaller villages. (Of course if you are using the energy for transport, then biofuels are much better because the energy can easily be stored and transported over long timescales. But that is not what I'm interested in here). Does anyone have any other information, opinions, experience of these types of systems? Have I overlooked any significant arguments on either side? I may soon have an opportunity to visit a remote solar installation that is backed up with a Diesel generator (as far as I know using petrodiesel) so wish to find out as much as possible beforehand.

RE: [biofuel] Biodiesel in Thailand.- Biodiesel is irrelevant without an abundant feedstock.
Hello Peter, The study was done in Hawaii and I will have to search in my notes to send the reference paper location. I looked in my technical references and the complete reference was not there. (It was inserted later by one of my colleagues). It's somewhere, but will take a little time to unearth. In the meantime, you may find it on the Internet if you look for a Hawaii study on fuel ethanol using paper. Our researchers are working with various biochemical innovations to further enhance the process. I'll post our good news when we have a proven process. Peggy Hi Peggy, Do you have any reference or web links to the process? It would be another interesting area to look at. Hi Peter, Just got back. I think that Cambodia is a really good target. Since as you said there's no oil refinery there. My initial gut feeling was that BD can be developed in Vietnam also. But I have since found out that Vietname has just constructed an oil refinery and it should begin operational soon. I hope that your venture in Cambodia will be successful. Do keep us updated. God Bless, Caleb --- Peggy [EMAIL PROTECTED] wrote: - Hello Peter, It is possible to make fuel ethanol from discarded paper and food waste (non-dairy and no meat) making fuel ethanol another alternative to biodiesel as well. Peggy Hi Caleb ;; I agree with you 100% about used frying oil being a questionable feedstock. There simply isn't enough of it to make any significant business out of it, and it is spread out over a large geographic area. Yes, sure the backyard tinkeres can make a go of it. But as soon as you start to buy any significant quantites, the price will surely rise, plus you have significant collection costs. You can estimate the available quantity by trying to think about how much frying oil you personally use, then add in some extra to account for the fried donut or fried chicken that you ate at the restaurant. Then compare that to how much diesel you use. Then add in the diesel used for your electricity, all the transportation costs to bring your food to the supermarket, ect. For me I use about 100 times more diesel than frying oil. So then we could roughly estimate that if a city uses for example 1 million liters of diesel a month, there would be 10,000 liters of used frying oil. But only a small fraction could be recocovered (you couln't recover the used frying oil that I personally use, for example). My conclusion is that a very small number of people could make it work, but as soon as a few more people try, supplies will dry up. That's why biodiesel is irrelevant without an abundant feedstock. Please don't forget about all the people dying, being killed, destroyed lives in the middle east over oil wars. Then add in the huge cost in military hardware, all the lost productivity of the men figting instead of working, and I'm not so sure that the cost of diesel is lower than the cost of biodiesel made from palm oil. Yes Malasia is the world leader in palm oil plantations, so this would not interest you. But Cambodia has no oil plantation and no oil wells either. They are net importers of both commodities. So they are very interested in both possibilities. Yes please keep me infomed about the BioFuel conference in December. Best Regards, Peter G.

The industry is well established. There was a push for BioDiesel back during the 2002. But since then Palm oil prices have risen by almost 100%, which makes it more profitable at the moment to export it overseas as cooking oil than to convert it to biodiesel for local consumption. Though rising oil prices might actually reverse all that. Diesel prices in Malaysia is far too cheap. According to the latest prices, we're the second cheapest after brunei. So pushing for BioDiesel is going to be hard in Malaysia. Plus we're a net exporter of crude oil. I have plans as you to perhaps develope a small biodiesel industry in Singapore based on used cooking oil. Still doing a lot of ground work at the momement. Singapore is moving towards euro IV emission standards, and biodiesel can help offset some of the cost of migrating to euro IV disels here. Initial investigation into used cooking oil as a feedstock here, indicate that it might not be a reliable source of feedstock. However we are not giving up hope yet.

Re: [biofuel] Question - efficiency of sunlight conversion
Hi Hakan, Donald Donald, One very important part for biofuels that you forgot, is the positive effect on job creation and the village economy. It is possible reselling and creation of income for the village. Maybe the following can give you more ideas. http://www.undp.org/seed/energy/contents.html Biofuel will also open up the possibility to use it for transportation, work, water pumping, etc. Its labor input is not a negative, it is a positive, since it is local. Hakan That's quite right, Hakan. It's basic to Appropriate Technology development to make maximum use of local resources and reduce imported technology (or imported anything) to a minimum, preferably to zero. Local resources include local know-how. Rural villagers don't know from PVs but they do know how to grow things, they know their local crops, and the local plants and trees too even if they don't grow them. This is one reason that local crops almost always do better than crops imported from outside the community, even though the imports might be much higher-yielding (in theory), especially if the object is community development, not just production. Even when overall production is higher, it might not benefit the community - there are many cases of higher production having the opposite effect, leading to increased hunger for instance, even to peasants losing their land. Yet such projects are often hailed as a success because the yields were higher, never mind all the babies that get chucked out with the bathwater. Another important aspect is that the selection of local crops and local knowledge and skills provides further opportunities to involve the community in the decision-making process, which is also a key factor in the success of a community development project. I could go on, but you can see how these factors favour a biofuels solution over PVs. Use of biofuels could mean the option of using a locally produced diesel motor in some cases, produced in the local region anyway if not in the village. Lister-type diesels, for instance, are still made locally in a number of 3rd World countries, and where they're not made there's often widespread familiarity with them. Local mechanics know how to handle them, and local or regional workshops can make parts for them. Oilseed presses and other equipment can also be produced locally. All of this benefits the local economy more than any totally imported technology could do, especially something high-tech like PVs, well beyond community reach. With PVs nothing is transferred except the narrow function of the technology itself, along with continued or increased dependence on outside sources. Then there's the question of battery renewal, and of what to do with the dead batteries. We've had some furious arguments about this here before. A guy named Jerry Dycus proposed PVs as a general solution to 3rd World power provision, and insisted against all reason that all batteries are recycled and it could not possibly cause problems. Even in the US, where it's rather doubtfully claimed that 97% of batteries are recycled, that still leaves about six million batteries a year that don't get recycled. 3rd World countries, especially rural areas, have no infrastructure for battery recycling. I've seen some really horrible things being done with dead batteries. In one case they were being ground up and sold to farmers as zinc fertiliser (the soils there were said to be short of zinc). Just think of that. Well, it wasn't just me, dear old Jerry argued with just about everyone. He got so angry he decided the whole list was anti-EVs, which it most certainly is not, but he started telling people we don't like EVs here, managing to wreck the EV discussions, and it still hasn't recovered. He was also sneering at people because there's lead in their computers. Very silly stuff. Anyway, never mind all that, the batteries are a question to be dealt with. Of course we're generalising here. The best we can do is to identify good operating principles - principles, not rules. Which turns out to be the better choice will depend on the circumstances in the particular village, which could easily turn any prior general conclusion on its head. Some more comments below...

Re: [biofuel] Diesel and biodeisel
I'm looking to purchase a new(or newer Jeep) in the near future. I've seen that Jeep is now coming out with a new diesel version of the Liberty. My co-worker said that diesel car produce more pollution then regular gasoline vechiles. I thought it was opposite, which is true? Also, I live in an urban area and would like to eventually wean off gas and into biodiesel. Are biodiesel sources in urban areas (particularly in the DC metro area) readily available? Hey welcome to teh list! Diesel cars pollute less in terms of greenhouse gases, VOCs and CO emmissions. They produce more NOx and PM pollutants. The choice is yours which is the bigger threast. I'm convinced its the VOCs and greenhouse gases. To answer your question about biodiesel...you cna run the new diesels oin it and it may or may not be readily available in DC. Here's a place to look and see if you ahve a public pump www.biodiesel.org Sorry can't make it hot. Certainly don't believe everything tehy tell you but its a start. Either way, it'll be expensive unless you brew your own, which is certainly not as hard as it sounds. If you follow the directions on JTF you should be able to make good biodiesel. Think the new diesel Libby will get 24-28MPG, but that's just a WAG.

For the purposes of this post, I will assume that we are trying to provide electricity to power refrigerators, lighting, miscellaneous equipment such as telephones and computers (even remote villages can have satellite connections to the internet these days!). This would be a light load and not include industrial use nor electrical heating/cooking. Let's think about the loads a bit, particularly refrigeration. In this case, we don't really need to store electricity, but coolth. So one approach would be to develop a solar-powered icebox. Have the PV panels run a conventional refrigeration unit when the sun is shining to make ice in the top of the icebox. A sensor can control a fan to pull air through the ice into the refrigerator when required to maintain temperature. Some electricity is still required for the fan (the sensor could be a simple bimetallic switch), but much less than for the compressor, so that would reduce electrical storage requirements significantly. So I will propose two solutions, both of which are used in various places: 1) Grow an oil crop, use it to power a diesel generator 2) Install photovoltaic solar panels and use a battery system to store the energy overnight Now I'm trying to get an understanding of the pros and cons of these two approaches, and which would be better for a particular location.

For a remote, stationary application, I would seriously consider nickel-iron batteries (Edison cells). More expensive (mostly due to lower production I expect), but less toxic (there is a caustic electrolyte), and can be very long-lived, reducing the disposal/recycling issue considerably. 2) Biofuels are often produced from crops that are grown in an unsustainable manner. What are the effects on biodiversity of this? How can this be counteracted? Are there any comparable environmental issues in the manufacture of solar systems? 3) Do the levels of expertise required to install and maintain a solar system make it inappropriate for use in remote villages? PV panels are effectively non-repairable. Solid state controllers are also effectively non-repairable. However, in a simple installation (which can be fairly large), regulators are not really necessary, if someone is prepared to monitor the battery charge state on a daily basis (and do some discharging if the batteries are being overcharged).
