VEGETABLE OIL UTILIZATION

NOW, IT IS POWER OF THEGREENER KIND.The virtuous circle in power generation is thedream o the modern world: a power plantthat does not increase the sum o greenhousegases, that uses renewable uel and that bringsthe energy required to raise the standard oliving where it is most needed. A ew years agothat would have seemed a pipe dream. Today

it is reality.Wrtsil liquid bio uel power plants use

highly e cient reciprocating diesel enginesto turn clari ed crude vegetable oils intoelectricity and heat. Liquid bio uel can beproduced rom practically any oil-rich crop,

rom oil palm, soy, rapeseed and olive tosunfower seeds, grown in many regions allaround the world.

The use o vegetable oils or engineuels may seem insigni cant today. But

such oils may in the course o timebecome as important as petroleumand the coal tar products o thepresent time.

Electricity provided or the grid should bestable. Many green energy solutions likesolar and wind power depend on weatherconditions. Wrtsil liquid bio uel power plantsrely on dependable, renewable resources ando er high overall plant per ormance at alltimes.

Surprisingly, bio uels have to o er just as much to business people as toenvironmentalists. Making money whiletaking the environmental issues o today into

consideration is a good investment now andor the uture.

World energy demand is increasing steadily. At the same time, the Kyoto agreement and

general concern about the environment areraising the need to reduce greenhouse gasemissions. Wrtsil has developed technicalsolutions to meet both needs: liquid bio uelpower plants o er sustainable powergeneration with practically zero greenhousegas emissions.

In many countries, owners o power plantswith low greenhouse emissions bene t twiceover: rstly rom selling their electricity tothe national grids, and secondly rom green

incentives.Still, the uture o liquid bio uels depends

on the availability o the uel and the solutionsto produce it in an environmentally and

GREEN ENERGYINCENTIVE SYSTEMS There are various incentive mechanisms,including the Green Certi cate, ormotivating companies to en orce greenenergy. These are nancial contributionsat community, national and regional levels,the renewable energy certi cate system,and grants o origin.

The EU Emission Trading Schemewas launched on 1 January 2005 togain market experience be ore the KyotoProtocol enters into orce in 2008. The

Kyoto Protocol commits the EuropeanUnion to reduce the 1990 levels ogreenhouse gas emissions by 8% between2008 and 2012. Now the EU countriesare working towards a cross-union tradingsystem, the details o which are stillevolving.

The Clean Development Mechanism(CDM) and Joint Implementation (JI) arefexible project-based mechanisms thatoperate under the Kyoto Protocol.Interest in the abatement o greenhousegases is also rising outside Europe, e.g.in Japan, Malaysia and India. Japan, orinstance, has passed laws to promotethe development and introduction opetroleum-substituting energy sincethe 1980s. In Malaysia the target shareo renewable energy is 5% o the totalsupply. Also biomass residues rom thepalm oil sector o er huge potential energy

economically sound manner. At its best, bio uelproduction creates local job opportunities, thuspromoting social and economic cohesion. Italso improves regional uel supply security byreducing the need or imported uels. In somecases, energy crop cultivation might even helpto ght soil erosion.

Sound economics combined with superioreco- riendliness!

IN FACT, RUDOLF DIESELRAN HIS FIRST ENGINE

BACK IN 1900ON PEANUT OIL.

Liquid bio uel has been known since thebeginning o the industrial revolution. Butit is only recently that environmental andcommercial pressures have resulted insubstantial research into maximizing e ciency

or electrical power generation. The dieselengine, based on compression ignitiontechnology, turns vegetable oil more or lessstraight rom the crop into electric energy.

It is in the uel eed system where the majorresearch on the larger medium-speed engineshas taken place. Medium-speed engines canrun on most qualities o heavy uel oil (HFO).These engines have or years proven their worthas power generating sets or electricity under

the most extreme conditions on the planet.While optimizing our standard engine

design, we developed a uel eed systemwhich controls the temperature and viscositythroughout the power plant. This eliminates

Early 90s. Testing o bio mass based pyrolysis oils.

April 1995. A 200 hour engine test with rape

A LIFETIME OF CLEAN ENERGY IS ENSUREDBY SOLUTIONS BEYOND THE FUEL.

To reduce the total o greenhouse emissions,Wrtsil liquid bio uel power plants aredesigned to operate on unprocessed vegetableoils without any supplementary energy or

uel re nement needed. The oils can typicallybe extracted with simple methods so that eventhe CO2 emissions associated with the uelre nement are minimized.

The sulphur emissions are insigni cantcompared to those associated with ossil

uels because vegetable oils do not containsigni cant amounts o sulphur.

The selective catalyst reductiontechnologies or NO Xabatement typicallyenable an 8590% reduction o NO X emissions rom the exhaust gases.

Particle emissions (PM) in liquid-bio uel-based power plants depend mainly on the ashcontent o the source uel. Experience has

9

shown that with good-quality liquid bio uels itis possible to reach low PM levels that meetstringent European standards.

Moreover, with vegetable oils the carbonmonoxide and hydrocarbon emissions arelow due to the highly e cient diesel engineprocess.

The power is also generated with minimaluse o water, so the impact on water resourcesis negligible.

Last but not least, Wrtsil liquid bio uelpower plants o er a very high simple cycleelectrical e ciency. You get more output oryour input!

POWER PLANT OUTPUT RANGE

THE MONOPOLI CHP PLANTItalGreen Energy in Italy and Wrtsil combined tobuild the worlds largest power plant or simultaneousgeneration o electricity and heat uelled exclusivelyby straight vegetable oil. The plant commissioned thefrst two Wrtsil 18V32 generating sets in August2004 with a total capacity o some 16 MW. In 2005the plant extended its capacity to 24 MW and thelatest extension o 100 MW is under construction andwill be in commercial use early in 2007.

Located inside the existing vegetable oil refnery, theplant supplies both green electricity to the nationalgrid and steam and power to satis y the actoryprocess demand. Fuel testing, detailed engineering,delivery o the ull generating set package, start-upand erection supervision were all included in ourdelivery.

Wrtsil offers liquid biofuel power plants in the range of 1300 MWusing Wrtsil 20, Wrtsil 32 and Wrtsil 46 prime movers.
