Re: [biofuel] Biox process, still more details
Another Fuel From The Farm Biodiesel gets a long-needed boost from a tax exemption, improved technologies and the ever-rising cost of petroleum. Source: Toronto Star [Aug 13, 2002] Walking through his 31-acre soybean field near Woodstock, Liam McCreery broke off a sample pod from this year's crop. By early October, the broad-leaf plants will yield white pea-size beans by the tonne. But like Rudolf Diesel, inventor of the diesel engine, McCreery, head of the Ontario Soybean Growers, also has a shrewd eye on the longer-term. We harvest solar energy, the 38-year-old farmer says, drawing attention to the fact that plant sources such as canola or soybean combine sunlight with carbon dioxide and soil nutrients to grow. It's long been known that vegetable oil, and oil made from waste animal fats, can be used in diesel engines. When German inventor Rudolf Diesel himself proposed it, he was hoping to make a local source of inexpensive fuel available to communities and also noted that burning vegetable oil cut pollution from the workhorse engine he invented. Biodiesel emits no sulphur, reduces black, lung-clogging particle matter by 80 per cent, and produces 60 per cent less carbon monoxide than petroleum diesel. Importantly, the carbon dioxide produced from the combustion of soybean oil as biodiesel is claimed back from the atmosphere by the next crop. Biodiesel can directly replace petroleum diesel fuel or be blended in any ratio. And it is compatible with any standard diesel engine. In fact, the slippery quality of biodiesel fuel has been found to lubricate engines, prolonging life and boosting performance. Those virtues aside, high production costs and poor supply infrastructure have kept the fuel out of the mainstream for decades. But now, a new tax break on biodiesel, rising fossil-fuel prices, and breakthroughs in production and distribution may give the technology a boost. With a big push on towards greener hydro, the truck fleets of Toronto Hydro are powering along this summer on biodiesel imported from the United States. So far, the biodiesel being tested shows a significant reduction in harmful exhaust emissions, Hydro reports. Even a B20 blend (20 per cent vegetable oil and 80 per cent diesel mixture), notably cuts down on pollutants. Also this summer, more than 100 Montreal city buses are running on a diesel mixture of waste animal fat and old restaurant grease. Unbeknownst to many, Janet Ecker's debut as the new Ontario finance minister created a stir across the biodiesel community. In the June budget, a tax exemption of 14.3 cents per litre provincial fuel tax on biodiesel was introduced. Ethanol has enjoyed a tax break for years. Striving for a cleaner environment, a provincial committee has also recommended that all diesel sold in Ontario must either be biodiesel, contain ethanol, or be a combination thereof by July 1, 2006. When Tim Haig, president and chief executive officer of Biox Corp., heard about the tax exemption, he reportedly offered to give Ecker, a big, sloppy kiss. Biox Corp. is a pilot biodiesel project in Oakville which stands to benefit from the policy. The small processing facility is producing one million litres of biodiesel from oil derived from soybeans and waste animal fat. Biox expects to open its doors commercially early next year, with a full-scale 60-million litre capacity. The Biox process, for which a patent is pending, is based on a discovery by David Boocock, a professor at the University of Toronto. About eight years ago, Boocock, now 60 and former chair of the chemical engineering and applied chemistry department, discovered a process that eliminates one of the chemical steps traditionally needed to create biodiesel. We believe that, given the choice, everyone would choose green if the cost was the same Tim Haig President and chief executive officer Biox Corp. The Biox process is expected to cut costs considerably. At the high-tech pilot plant, located at an old trucking depot, compact equipment consisting of coils and chemical reactors convert raw vegetable seed oil or waste animal fat into litres of golden-colour biodiesel. From start to finish, the process takes about 40 minutes. A competitor in Europe takes a litre of oil extracted from vegetable seed and turns it into a litre of biodiesel for about 25 cents. The Biox process is designed for producing the same litre of biodiesel for about 7 cents a litre (Canadian dollars). One business plan is for the company to set up franchises around the world which would lease the equipment to a range organizations, from oil companies to rendering plants or anyone else who wants to produce biodiesel and sell it. The equipment is designed to be user-friendly; other than for maintenance of the machines, no specialized technicians are required. It means that, typically transport trucks can dock at the plant and pipe in the raw material, and truck it

No doubt most of you have seen this by now, but in event you haven't, here it is: Glenn Ellis Environmental Science Engineering - A HREF=http://www.esemag.com/index.html;www.esemag.com/A - May 2001 Production of a cost-competitive biodiesel fuel alternative to petroleum diesel Functional pilot unit located in Oakville, Ontario, processing one million litres per annum. Research has shown a number of important benefits of biodiesel fuel as an alternative to fossil fuels. The environmental and health benefits of this non-toxic and biodegradable fuel include its potential for reducing harmful exhaust emissions, decreasing green house gas (GHG) production and enhancing diesel engine performance as a lubricity additive. As well as contributing to a cleaner environment, the use of biodiesel, produced from recycled vegetable oils, agricultural seed oils or waste animal fats and grease, should also benefit and increase the income of the agricultural community in North America. Up to this point, however, the production and commercialization of biodiesel as an alternative fuel to petroleum diesel has seemed unlikely, due to the costs associated with its production (approximately three times as much as petroleum diesel). All companies currently producing biodiesel still employ a high pressure, high temperature method that is energy intensive and extremely costly. Or they use a chemical method that does not achieve ASTM standard Biodiesel in a one pass cost-effective manner. Both the seed oil (soybean, canola, etc.) and the yellow grease markets are at a historic all time low with regard to market pricing. It is anticipated that prices may remain depressed for sometime primarily due to the awareness of BSE (Mad Cow's disease) and the international effect it has on the animal proteins market. Biodiesel, however, could be produced from both seed oil and yellow grease. The Process The BIOX process, a new biodiesel process developed by the University of Toronto, has successfully demonstrated, in a laboratory setting, that biodiesel fuel (produced from recycled vegetable oils, agricultural seed oils or waste animal fats and greases) may soon become a viable, cost-competitive alternative to petroleum diesel. Professor David Boocock of the University of Toronto, and developer of the BIOX Process, has examined the process of base-catalyzed transesterification (specifically transmethylation) of vegetable oils to produce biodiesel methyl esters. The kinetic data for this reaction has been previously misinterpreted. At the University of Toronto he has shown that the methanolysis is slow because the initial reaction mixture consists of two phases, and the reaction is, therefore, mass transfer limited. The problem has been solved by the selection of inert co-solvents that generate an oil-rich one-phase system. This reaction is 95% complete in ten minutes at ambient temperatures, whereas previous processes required hours. Continuous processes are now feasible. The acid catalyzed process, which is required when the substrate contains fatty acids, is complete in minutes rather than the usual several hours. The traditional base-catalyzed method for producing fatty acid methyl esters from triglycerides and methanol has several disadvantages, including: The reaction is slow at ambient temperatures. The reaction does not go to completion, and therefore requires a second and even third pass to achieve the necessary purity. The reaction cannot handle substrates which have fatty acid contents much above one percent, simply because the acids neutralize the catalyst to form soaps.The new process addresses these problems in the following ways: Uses an inert, cheap, recyclable co-solvent to make the reaction one phase, thus improving mass transfer and thereby, the reaction rate. Uses more methanol to increase the polarity of the mixture, which maintains the ionization of the catalyst. For substrates containing fatty acids, it first uses a one-phase acid-catalyzed step to convert the fatty acids, before using base catalysis to convert the triglycerides. In the two-step process, approximately 30 minutes is required to convert the fatty acids at close to the boiling temperature of the methanol (60C). The base-catalyzed step is complete in seconds. Has a recycle stream of methanol and a co-solvent, and the latent heat of condensation is used to heat the incoming feedstock.The process is claimed to be the only biodiesel production process that will be able to compete with petroleum diesel on a production cost basis, and the only process that can successfully exploit high fatty acids to produce biodiesel. The process is able to deal with animal fats and greases. It is estimated that by using both used agricultural oils and waste grease, costs can be cut by as much as 50 percent, making biodiesel competitive with petroleum diesel. The costs of biodiesel using
