How to Use Biodiesel Processor for Producing Biodiesel From Vegetable Oil

A biodiesel processor is a combination reaction vessel. It is used for producing biodiesel from vegetable oil.

An industrial processor is very much considered convenient for production volumes, which can’t produce more than10,000 t/year. The reaction and distillation process of the alcohol is a batch processing. The decantation use to happen continuously.

In the industry, a static mixer is being used with the esterification catalyst called sulphuric acid and then methanol and vegetable oil are mixed. The reactor is used for esterfication of free fatty acids. Where as in another static mixer, an alkaline catalyst generally potassium hydroxide is getting used, this is added to the methanol-oil mix for the transesterfication.

Now in the Second reactor, the process is called transesterfication occurs. While in the third mixer, various outcomes from a reaction are biodiesel, glycerol and methanol solvent. It is being nullified by introducing a simple mineral acid. The alcohol being separated in flash vaporizer called as distillation unit. The condensed Vapors of methanol are sent to the reception unit for introducing again in the cycle.

Now the remaining products in the flash vaporizer namely, biodiesel, glycerol, salts and water, are sent to continuous decanter, which separate biodiesel from rest of the by-products. The light phase which is getting created in the decanter is en tot the storage tank and remaining heavy phase is sent to another storage tank for latter purification. After this phase, it contains 80 to 90% pure glycerol, water and salts.

Biodiesel and glycerin purification ca be done in high vacuum evaporators. There is typical design called as wiped film evaporator, where products used to be clearly differentiated from various salts by thermal as well as mechanical methods.

The quantity of raw material which is required to produce 1000kg of biodiesel and 112 kg of glycerol.

It requires 1030kg of refined vegetable oil. It requires 103kg of Methanol. Catalyst of quantity 6. 2kg used in process of biodiesel is sodium hydroxide or potassium hydroxide. Mineral acid required quantity is 6kg

There are some other services which should be make available like,

Cooling water service 20m

Steam 350kg

Electricity required 50KWh

Nitrogen required 3. 2m

If you are making biodiesel at home, you should use any triglyceride fat or animal tallow or vegetable oil. You should have a strong base namely, sodium hydroxide or potassium hydroxide, also pure alcohol. You should have longer chain alcohol; it must be longer than isopropyl alcohol. You can use oil for processing which is often obtained in restaurants.

There are different methods for producing biodiesel. It is generally produced in small batch processors in the garage. But now some used to adapted processors to fit at the back of vans. It is transportable. One of the major difficulty being Dealt by various biodiesel homebrewers is just to make a mid scale biodiesel processors sufficiently very simple to cheap, safe and easy to make appropriate.

Bio-fuel Crops Producing Bio-diesel

A Healty and Viable Future in Vietnam

The company now boasts 22 employees, including scientists, farmers, international businessmen, industrial workers and of course family.

GreenEnergy`s corporate mission aims to bring large tracts of rural land under scientific but basic cultivation of bio-fuel feedstocks, bringing with it employment and entrepreneurial opportunities to potentially thousands of Vietnamese rural poor, while providing inputs for GreenEnergy`s core business, the refining and marketing of bio-diesel.

It is a win, win situation for everyone because not only does cultivation of this vegetable oil require only marginally arable, war damaged or barren land, this also means its activities do not compete with other food production which avoids putting upward pressure on food prices.

N.B (Vietnamese Government has identified seven million hectares as marginal, barren or war damaged land).

In addition GreenEnergy`s operations achieve a renewable and sustainable fuel source for Vietnam to continue its development with all the attendant social, economic and environmental benefits in producing clean energy.

Because of the scale and potential of the bio-diesel industry in Vietnam and indeed globally, where tens of millions of bio-fuel crops will have to be grown to substantially replace fossil fuels, a ‘second green revolution’ is possible, bringing with it true improvement in the lives of the rural poor and vegetable oils can play a significant role in helping to ameliorate global warming as a key aspect of climate change.

Global warming, a key aspect of climate change, now clearly recognized as a result of a concentration of greenhouse gases (GHGs) in the atmosphere – has the worst impact on the climate.

Carbon dioxide, the most common of GHGs, is emitted during the burning of fossil fuels.

The Kyoto Protocol gazetted in February 2005 requires participating countries to cut carbon emissions.

Further to this, rising crude oil prices and the need to reduce dependence on imported oil has made it necessary for net oil importers to think of alternative energy sources. The precarious situation with fossil fuel supplies coupled with the ability of bio-fuels to lessen that risk, makes it feasible for the global economy to revert its focus towards agriculture and those traditionally engaged in it, thus offering a potential boon to Vietnam’s rural sector.

Full bio-diesel use would reduce net CO2 by over 78% compared to petroleum diesel and up to 16% with the use of blends comprising 20% bio-diesel.

While both fuels are almost equally efficient at converting raw energy resources into fuels, bio-diesel has a larger part that is renewable .Similarly, bio-diesel is non-toxic and environmentally friendly as it produces substantially less CO2, ensuring sustainable environmental practices.

GreenEnergy has recognized this mammoth task and has adopted a dual strategy for attaining its goals in Vietnam.

1.Public – Aggressive initiatives to “jump-start” the production side of bio-fuel feedstocks by forming a partnership with Vietnams Central Government and People’s Committees as well as aid agencies to help put large tracts of marginal land under bio-fuel crop cultivation quickly.

A memorandum of understanding and support was signed by the Peoples Committee of Binh Dinh Province and Green Energy Vietnam on the 8th of December 2006 and the 500 hectare Binh Dinh Research and Training Facility for the Cultivation of Biofuel Feedstocks has been established, known as BDF- FARMER ENERGY- a working laboratory devoted to developing the bio-fuel industry for the benefit of Vietnamese rural poor.

2.Private – Includes GEV investments to retain its ‘First Mover’ advantage by securing its proprietary feedstocks, expanding its physical plant refinery presence and continuing to build its integrated supply-chain, complete with forward contracted suppliers and customers.

It is in this first arena, Public Initiatives, that GreenEnergy sees co-operation with aid agencies.

Some of the substantial and sustainable benefits that the cultivation of bio-fuels crops can contribute to Vietnam are:

1. Real cash growth, raising the annual income of $820 to $1,300 U.S. for thousands of marginalized rural families.

2. Private homesteading for the rural poor.

3. Stress relief and barren or war damaged land reclamation.

4. Enfranchisement of poor, rural women.

5. Retention of scarce foreign currency reserves and

6. Independence from the uncertainties of global mineral oil markets.

The People`s Committee of the Province of Binh Dinh and GreenEnergy, Vietnam, in full realization of the enormous impact this Research and Training Facility will have for all of Vietnam`s rural communities, cordially invites any and all organizations seeking positive change in the livelihood of rural Vietnamese to form an active Partnership in the development of this Research and Training Facility.

The Binh Dinh Facility wants to be a catalyst in harnessing this opportunity for all stakeholders and delivering:

. A path for the rural poor to climb out of their deprivation rather than fall further behind.

. A renewable, sustainable and viable alternative to fossil fuel for Vietnam’s surging economy. and an industry that rejuvenates, rather than degrades the environment.

Introduction to the oil plant Jatropha.

The oil plant Jatrophas curcas (L) (Jatropha) or physic nut, is multipurpose and drought resistant, growing to a height range of 2 to 7 metres for the Asian species and it not only flourishes in tropical and sub-tropical climate zones but even in areas absent of water.

Because its leaves and stems are toxic to animals it is often used as a protective hedge around farm houses, gardens and fields.

It also reduces soil damage caused by erosion from wind and water and traditionally the seeds were harvested by women for medical treatments and local soap production.

In Thailand, Jatropha normally flowers twice a year, in dry and rainy seasons with seed harvesting conducted approximately 60-90 days after flowering and the oil plant has a productive life of 20 years.

Because the market is probably not yet mature enough for the plant to generate enough income solely from oil extraction, a holistic rural development approach has to be taken into account in order to exploit all potential uses of the Jatropha plant. This approach is known as the Jatropha System.

The system focuses not only on the use of the source as a fuel, but rather as an element, to activate a system combining ecologic, economic and income generating activities.

Consequently, the Jatropha System offers four main aspects of development aiming to better the livelihoods in rural areas, especially for women and farmers:

. Renewable energy- bio-diesel

. Erosion control and soil improvement

. Promotion of women and

. Income generation.

About one-third of seeds can be extracted as oil that has a similar energy value to diesel fuel. The oil is extracted by hydraulic pressure and then filtered through an intensive sleeve that can then be readily used without any complicated refinery process, directly available for small diesel engines as a substitution for diesel oil, without engine modification.

This oil can power engines, such as water pumps, tractors, hand mowers, other farm machinery and rice milling machines and by using this domestically produced oil as a substitution for imported oil, significant cash savings can be made.

GreenEnergy Ltd have already committed a considerable amount of time, money and resources to this environmentally sound an economically sustainable project in Vietnam and welcome further input from other interested parties.

It is also their belief that at an international level, stakeholders involved should perform a three pronged approach, with mutual knowledge, technology transfer, genetic development of high oil content in the seeds and exchange of Jatropha species, together with investment and trade linkage.

The Various Advantages of Producing Algae Biodiesel

Algae is a major renewable fuel which can be used to manufacture Biodiesel. One of the companies in New Zealand successfully developed a system for using sewage waste as a substrate for algae and then it produce bio-diesel. An alga is considered as the highest yield feedstock for biodiesel that can produce more enough oil compared to soybeans when grew in an acre.

Actual Biomass algae produced from field trials, which is conducted during the NREL’s aquatic species program. It is being converted using the actual oil content of the algae species grown in the specific program.

There are various advantages of producing biodiesel from algae, which include rapid growth of the plant. Using Algae Biodiesel gives high per acre yield. Algae biodiesel does not used to contain sulfur, toxic materials and it is highly biodegradable. There are some species, which are ideally suited for algae biodiesel production, because their high oil contents in some species.

Algae used to develop from small, singled celled organisms to cellular organisms, some algae have complex distinguished form. Algae can be easily seen at places like damp, bodies of water. Algae are common in terrestrial as well as aquatic environments. Like any other plants algae require three elements to spring up sunlight, carbon-di-oxide and water. Plant algae and some other bacteria convert sunlight to chemical energy, which process call as photosynthesis. Algae used to contain 2% and 40% of lipids or oils by weight. If algae have greater oil, it may results in lower yield annual food crops such as soybeans. Currently only 0.3% of the land of the US, it is getting utilized to produce enough biodiesel.

Species of algae with up to 50% oil content have conclude that only 28000km land getting used to produce biodiesel. Unused desert land could be used for effective growing of algae.

Following is the productions which obtained in an entire year. In the winter months algae productivity used to drop.

Companies Producing Algae Biodiesel Fuel

When it comes to biodiesel production one of the easier methods involves the use of algae. Not only is it easier, it is also very efficient. There have been studies carried out that have shown that algae produces up to 30 times more oil than using the other different crops that are currently used for production for every acre.

The other advantages of using algae include the need for very little land to grow your crop. Also it seems that the sulfur content is non existent, they are no toxins and the fuel generated will be highly biodegradable. There are actually some special species of algae that are grown specifically for production. These contain higher levels of oil than normal, often up to 50% and they also grow really fast.

There are now many companies that use this natural resource in the production of biodiesel. Aquaflow Binomic Corporation (ABC) is based in New Zealand. They harvest their algae directly from the settling ponds of standard effluent management systems and other nutrient-rich water. Their process can actually be adopted for many other industries.

There is also Aquatic Energy, LLC which was started in 2006 to pursue their vision of producing renewable energy bio fuels in Louisiana, which is located in the Gulf Coast of the United States. Aurora Biofuels has successfully been operating a relatively small plant since August 2007 and this plant has consistently produced high quality biodiesel. They expect to have their first commercial scale facility in operation by late 2012.

Lastly I would like to mention Blue Marble Energy, which is based in Seattle in north eastern United States. Their main focus is on using wild algae and plant material to make biodiesel. However they have developed a very interesting production process that churns out fertilizer and other chemicals as a by-product.
