Chilled Ammonia Process

Principle• Cooled flue gas is treated with ammonium

carbonate in solution, which reacts with CO2 to

form ammonium bicarbonate

• Raising the temperatures reverses

the above reactions – releasing

pressurized CO2

Advantages• Energy-efficient capture of CO2

• High CO2 purity

• Tolerant to oxygen and flue gas impurities

• Stable reagent, no degradation possible,

no emission of trace contaminants

• Low-cost, globally available reagent

Chilled Ammonia ProcessField Pilot at We Energies

Validation Pilot Program

• Project participation through EPRI by 37 US

and international utilities

• Designed to capture 1,600 kg CO2/hour

• Operations commenced in June 2008

− Over 6,500 hours operation

− Achieved 90% capture in

continuous operation at full load

− Empirical data collected from pilot to date

supports “proof of concept”

− Initial data on steam and electrical energy

consumption is consistent with

expectationsCO2 Field Pilot at Pleasant Prairie

Pleasant Prairie Power Plant (“P4”)

A great technical success!

Validation Pilot at We Energies3-D View of Pilot

Validation pilot program

Advanced Amine Process

Principle• Flue gas is treated with aqueous amine

solution, which reacts with CO2

• Raising the temperatures reverses the above step – releasing CO2 and recycling the solution for re-use

Advantages• Proven in natural gas & syngas purification

• More efficient capture of CO2

• Higher tolerance against oxygen & trace contaminants

• Lower solvent degradation rates, leading to:

− Lower consumption of chemicals

− Lower emissions of degradation products

− Lower production of effluents and waste

Modified Jun 2009.

• CCS Facility proposed for EU

funding

− Capture greater than 1.8 million

metric tonnes CO2/year

Oxy-Combustion Process

Principle

• Air Separation Units are used toproduce pure oxygen stream

• Fuel is combusted in oxygen combined with recycled CO2

• Resulting flue gas is concentrated CO2

stream with impurities that are removedusing conventional air quality controlsystems and gas processing units

Advantages• Reliability: components exist, only adaptation to power gen and scale-up

• All types of boilers / firing systems adaptable to oxy to cover complete fuel range

• Rapid scale-up to large size possible after demos. Retrofit in Oxy can be addressed

• Large panel of entities involved in development, contributing to reaching solid consensus
