The Variety of Liquid Bio Fuels
Liquid Bio Fuels
A great varation of bio fuels canbe found
Approved by Wrtsil are: Vegetable based bio fuels:
Palm oil, Palm stearin, Rapeseed oil, etc.
Transesterified bio oils(biodiesel)
Animal based not approved DME (Di-Methyl Ether) not
approved Methanol & Ethanol not approved Bio oil alcohol mixes not
approved
Lower Heating value => Outputreduction

Sources of Liquid Bio Fuels
Sources of vegetable oils (2003) Palm oil (28.3M tons/year)
Malaysia (47%) Indonesia (37%)
Soy Bean (31M tons) USA Sourth Europe
Rapeseed (12.3M tons) North Europe
Sunflower (8.6M tons) South Europe
Total Oils&Fat production
2003: 123.5 million tonnes Animal fats 23M tons
28.3 Mtons is enough for 14000MW continous
power generation

Prices of Liquid Bio Fuels
Price development Palm oil price development
has been positive over longterm trend With HFO at 250 300 $/ton
and Palm oil at 400$/ton, thepower generation market
requires subsidies to becomecommercially attractive CO2 trading and incentives in
Italy, Holland and Germanyhave created local markets
for LBF power plants 0

Characteristics of vegetable oils
Varying characteristics Ash content
Clear oil & dark oils havedifferent level of ash
Influence on particulateemissions
Viscosity is highlytemperature dependant
Too cold -> wax Too hot -> polymerization
Phosphorus content Lifetime of DeNOx &
OxiCat
Acid number Influence on fuel oil system
wear & tear

MW in operation
MW development The introduction of incentives
in Italy has created a fastgrowing installed base of LBFplants
Projected estimates suggestthat up to 500MW of LBF
plants could be in operationby end of this decade

LBF business models
Four models Crudel Vegetable Oils
The primary model for using
LBF. Bio diesel
Today very expensive, notreally feasible for powergeneration
Waste oils from food industry
Karlburg plant model, but waslater changed to by products.Problem: Emissions
Waste or fuel? Which EUdirectives are to be used?
By-products
Main customers are companiesoperating in Bio-oil refinerybusiness
