Cycle Optimization is Critical to FEED Success

Optimizing NOx emissions atgas turbine exit vs. stack canreduce capital cost andimprove operating flexibility

Sharing water treatmentsystems can lower capital cost

Water / Steam optimizationbetween the process islandand power block is an iterative

process that takes time andgood communications to dowell

Conclusions

Near term global demand for gasification

based solutions is focused on projects that

produce high value products and canaddress climate change now

Using EOR for CO2 storage

Economic hurdles still exist for gasification

based projects that the next wave of projectswill address

Government financial support will helpaccelerate deployment

Longer term energy megatrends will drive

demand for gasification based solutions for

power, chemicals and clean transportation

liquids
