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
