Entrained Flow Gasification
Trends and OpportunitiesWith a huge variety of uses for syngas and H2, gasification is ideally suited to generate additional revenue from every ton of feedstock produced, while meeting even the strictest environmental regulations.

What is gasification?
Main Reactions:C + ½ O2 => COC + CO2 2 COC + H2O => CO+H2
CO + H2O CO2+H2

Market trends and opportunities for Gasification
• High dependency on environmental legislation • Currently weak demand for CO2 capture and storage solutions
• Availability and low energy density of biomass drive gasifier capacity and location

Alternative Transportation Fuels (CtL/BtL2)High-quality diesel from FT3-synthesisFuels with higher biomass content
Chemicalse.g. Methanol, Polypropylene, Ammonia,…
Synthetic Natural Gas
Refinery Hydrogen For upgrading products in refineries or in oil sands processing
Power • Large scale IGCC4 with CCS5 as environmental friendly alternative to Steam Power Plants
• Small scale power production via high efficient Biomass gasification systems
Is and will remain the market with the highest realization potential (CtC/BtC1)
Increasing demand for cleaner and lighter fuels are the drivers for higher H2 consumption within refineries
Serious alternative for (coal rich) countries, with lack on cheap natural gas availability
Volatile oil and gas prices, security of supply concerns and climate protection cause search for alternative fuel sources

BtL1 / BtE2 – Global gasifier market
• BtL projects mainly focused on markets for industrial scale chemical / transportation fuels production
• BtE mainly used for small scale power generation Japan: Feed-in-tarif available
Western Europe• Large scale projects in Netherlands and
Finland under development• Subsidies available
• Gasifier application in renewable applications forecasted to grow within the next years/decades• Short / Mid-term market will be dominated by small / medium-scale applications• Large scale lighthouse projects under development• Availability and low energy density of biomass drive gasifier capacity and location• Subsidies or feed-in-tariffs are key for biomass
• Financial decision guided by size and location, availability of feedstock, its energy content and processing costs
• Insufficient grid expansion (developing countries)
• Public opinion against fossil fuel plants (industrialized countries)
Asia Pacific Region (India/Indonesia/Malaysia/Thailand/Vietnam/…):
• Could support electrification of rural and remote areas, growth rate for small/medium scale applications
China• Underdeveloped as of today, but
government policy and subsidies announced
South-America:•Opportunities for BtL/BtE at sugar plantations (bagasse) and croplands
USA/Canada/Mexico:• Push through subsidies
already in place

Block flow diagram
Preliminary engineering results:
• Ship transport by Handymax or Panamax bulk carriers
• Buffer storage envisaged for 2 weeks, possibly in pyramid silo’s
• Density of torrefied material is fundamental for performance of gasifier
• Ash content of biomass is fundamental for gasifier design
• Additional bio-fuel storage is required
