Chilled Ammonia Process

Principle • Cooled flue gas is treated with ammonium

carbonate in solution, which reacts withCO2 to form ammonium bicarbonate

• Raising the temperatures reversesthe above reactions – releasingpressurized 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

A promising technology!

Advanced Amine Process

Principle• Flue gas is treated with aqueous amine solution,

which reacts with CO2

• At raised temperatures CO2 is released andsolution recovered for re-use

Advantages• 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

Oxy-Combustion Process

A sound technological option

Principle • Air Separation Units are used to

produce 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 reach solid consensus

Conclusions

• The Chilled Ammonia process is showing good potential and development is on track for commercialisation by 2015

• It is now time to move to large-scale demonstrations − EU and Canada are taking the lead to fund these programs

• CCS technologies for new and existing power plants are a must− Part of a solution that includes: efficiency improvements, nuclear

and renewable energy

• Alstom current partnerships and demonstration projects are designed to demonstrate key CCS technologies operating on both coal and gas

Alstom is committed to make CCS a successful technology!
