Nothing wasted
• Smaller scale facilities makes the most of the resources available
Better options
• Smaller, low cost plants need less gas or biomass to be profitable
— Enabling FT to be used for biomass and MSW projects
Velocys microchannel Fischer-TropschEnabling technology – process intensification

• Minimum feedstock volume
— A plant of 1,000 barrels per day (bpd) output (~200,000 tons of waste per year) could be economic, depending on local conditions, including tax regimes
• Minimum syngas volume
— A plant of 1,000 bpd output would need of the order of 28 million scf syngas per day (post clean-up & H2/CO ratio adjustment)

Practical considerationsUse of microchannel FT in biomass-to-liquids projects
• Gasification provider
— Selected by client
— MSW; e.g. AlterNRG
— Biomass; e.g. TCG Global, TRI, Enerkem
• Syngas quality
— Syngas clean-up is a major system component for BTL projects
— Soot-free, sulfur-free, ++
— Selection of syngas upgrading technology depends on gasification technology & feedstock
