how to prepare the bio diesel?

Question

i want manufacturing plant layout for bio-diesel preparation

Answer 1

Manufacturing bio diesel is relatively straight forward, it takes a triglyceride fatty acid and in the presence of a catalyst, removes the glyverine, replacing it with methanol (transesterfication) to produce a fatty acid methyl ester referred to as FAME or Bio Diesel.

The triglyceride fatty acid is normally present in plants such as Jatropha carcus.

Answer 2

You upgrade an old fashioned liquor still to whatever level of production is desired using modern equipment and quality test procedures. I'm certain that most engineering firms could properly design a plant to meet your requirements, but like all other industrial plants, there isn't a standard design. Got 10-15 million you want to invest?

Ethanol, E85, is sold now in over 1000 stations (not many, but growing) in the USA. Unfortunately the economies of scale necessary for economical production and distribution have not been approached and the price is still too high. More usage will bring the price down to levels that are truly attractive. It sells in NC currently for $2.49 per gal.

Answer 4

Biodiesel fuel is becoming more and more popular, which is no wonder, the soaring gas prices and the growing environmental awareness brings society to a point where it needs to consider its energy consumption carefully. With the rising price of gasoline and the prospect of even higher prices, it’s becoming evident that most people need to start looking for an alternative fuel source.

Answer 8

Biodiesel refers to a diesel-equivalent, processed fuel derived from biological sources. Though derived from biological sources, it is a processed fuel that can be readily used in diesel-engined vehicles, which distinguishes biodiesel from the straight vegetable oils (SVO) or waste vegetable oils (WVO) used as fuels in some modified diesel vehicles.

In this article's context, biodiesel refers to alkyl esters made from the transesterification of both vegetable oils and/or animal fats. Biodiesel is biodegradable and non-toxic, and has significantly fewer emissions than petroleum-based diesel when burned. Biodiesel functions in current diesel engines, and can supplement fossil fuels as the world's primary transport energy source.

Biodiesel can be distributed using today's infrastructure, and its use and production are increasing rapidly. Fuel stations are beginning to make biodiesel available to consumers, and a growing number of transport fleets use it as an additive in their fuel. Biodiesel is generally more expensive to purchase than petroleum diesel but this differential may diminish due to economies of scale, the rising cost of petroleum and government tax subsidies.

Production
Chemically, transesterified biodiesel comprises a mix of mono-alkyl esters of long chain fatty acids. The most common form uses methanol to produce methyl esters as it is the cheapest alcohol available, though ethanol can be used to produce an ethyl ester biodiesel and higher alcohols such as isopropanol and butanol have also been used. Using alcohols of higher molecular weights improves the cold flow properties of the resulting ester, at the cost of a less efficient transesterification reaction. A byproduct of the transesterification process is the production of glycerol. A lipid transesterification production process is used to convert the base oil to the desired esters. Any Free fatty acids (FFAs) in the base oil are either converted to soap and removed from the process, or they are esterified (yielding more biodiesel) using an acidic catalyst. After this processing, unlike straight vegetable oil, biodiesel has combustion properties very similar to those of petroleum diesel, and can replace it in most current uses.

Biodiesel feedstock
A variety of oils can be used to produce biodiesel. These include:
* Virgin oil feedstock; rapeseed and soybean oils are most commonly used, though other crops such as mustard, palm oil, hemp, jatropha, and even algae show promise (see List of vegetable oils for a more complete list);
* Waste vegetable oil (WVO);
* Animal fats including tallow, lard, yellow grease, and the byproducts of the production of Omega-3 fatty acids from fish oil.

Worldwide production of vegetable oil and animal fat is not yet sufficient to replace liquid fossil fuel use. Furthermore, some environmental groups object to the vast amount of farming and the resulting over-fertilization, pesticide use, and land use conversion that would be needed to produce the additional vegetable oil.

Many advocates suggest that waste vegetable oil is the best source of oil to produce biodiesel. However, the available supply is drastically less than the amount of petroleum-based fuel that is burned for transportation and home heating in the world. According to the United States Environmental Protection Agency (EPA), restaurants in the US produce about 300 million US gallons (1,000,000 m³) of waste cooking oil annually.[1] Although it is economically profitable to use WVO to produce biodiesel, it is even more profitable to convert WVO into other products such as soap. Therefore, most WVO that is not dumped into landfills is used for these other purposes. Animal fats are similarly limited in supply, and it would not be efficient to raise animals simply for their fat. However, producing biodiesel with animal fat that would have otherwise been discarded could replace a small percentage of petroleum diesel usage.

The estimated transportation fuel and home heating oil used in the United States is about 230 billion US gallons (0.87 km³) (Briggs, 2004). Waste vegetable oil and animal fats would not be enough to meet this demand. In the United States, estimated production of vegetable oil for all uses is about 24 billion pounds (11 million tons) or 3 billion US gallons (0.011 km³), and estimated production of animal fat is 12 billion pounds (5.3 million tons). (Van Gerpen, 2004)

Biodiesel feedstock plants utilize photosynthesis to convert solar energy into chemical energy. The stored chemical energy is released when it is burned, therefore plants can offer a sustainable oil source for biodiesel production. Most of the carbon dioxide emitted when burning biodiesel is simply recycling that which was absorbed during plant growth, so the net production of greenhouse gasses is small.

Feedstock yield efficiency per acre affects the feasibility of ramping up production to the huge industrial levels required to power a signifcant percentage of national or world vehicles. The highest yield feedstock for biodiesel is algae, which can produce 250 times the amount of oil per acre as soybeans.[2]
