GE Energy: gasification leadership
GE Energy’s Experience
• Gasification leader since 1948
• 65 facilities worldwide (+19 under construction)
• ~120 gasification vessels in operation
• 1966: first heavy fuel oil gasification
• 27 plants today on liquid fuels
• 27 turbines with syngas
• 1MM+ operating hours
• 33 projects globally that separate CO2

The HPG-ATC at the U of WyomingHigh Plains Gasification Advanced Technology Center:
Developing the next generation of gasification technologies
Status
• Site Selection…May ‘09
• Start PreFEED…May ‘09
• COD 2012
• PRB & other coals• Scaled facility• Commercial level gasification
– Dry feed (pressure/metering)– Dry injection (spray dispersion)– Dry gasification (O/C ratio)
• Complete process blocks– Coal feeding system– Gasification island– Carbon capture systems– Water treatment systems– Data acquisition & controls
Important configuration characteristics
8 /GE /
Configuration basis for presentation
• Note: GE does not own F-T technology
• Gasification to support 40,000 bpd CTL plant
• Choice of feedstock: Illinois #6 coal
• Diesel: 28,000 bpd
• Naphtha/LPG: 14,000 bpd
• Plant location: US

Project complexities
17 /GE /
Project complexities are massive
Integration is complicated by: • Increased schedule & cost (multi party contracts) • Risk allocation for financing • Wrapping for process/performance guarantee?
• No sole engineer• Multiple licensors
• Multiple operation scenarios • Turndown • Off-design periods• Polygeneration
Integration offers sizeable benefits: • higher efficiency• operator ownership of optimized plant performance• thermal balance (minimized waste heat)
Financing the highest hurdle: • CAPEX scale is enormous for large scale refinery equivalents• Securing financing in today’s environment• Need strong balance sheet partners
Integration = opportunity
Key results/data
19 /GE /
The results/performance
•CO2 from gasification step only1SSEB 2005, DOE 2007, RAND 2008
• CO2 production in tons/bbl? 0.23 Tonnes/bbl CTL*
• Needs of water in tons/bbl? 2.3 bbl water/bbl CTL
• Can biomass be added? Up to what %? Our customers have tested up to 5% … not in our current process design
• CAPEX $ for this 40,000 BPD plant (inside battery limits) Recent, public estimates $60-105k/bpd capacity1
