CCS Project Database
Company/Alliance: E.ON Thermal Power and Alstom Power
Location: Karlshamn, Sweden
Feedstock: Oil
Process: Boiler combusting high-sulphur fuel oil
Size: 5 MW
Capture Technology: Post-combustion with chilled ammonia
CO2 Fate: Undecided
Timing: The pilot was commissioned in April 2009 to operate for at least 12 months
Motivation/Economics:
E.ON and Alstom will be investing €11 million (US$ 15 million) in the pilot project at Karlshamn with the aim of introducing it at the new gas-fired plant in Malmö, Sweden.
Comments:
Located in southern Sweden, the pilot is retrofitted to an auxiliary steam boiler that combusts a high sulphur oil and has electrostatic precipitator (ESP) and advanced Wet Flue Gas Desulfurization (WFGD) technology installed for air quality control.
Designed to capture 15,000 metric tons of CO2 per year at full capacity, the pilot was commissioned in April 2009 and will be operated by Alstom for at least 12 months. The pilot is equipped with a significant amount of instrumentation to provide invaluable data and information necessary to master the operation of this post-combustion process.
Studies demonstrate that Alstom’s chilled ammonia technology results in an energy loss of approximately 10% compared to other methods of post combustion separation with losses of nearly 30% and can capture 90% of CO2 from flue gases. Alstom is operating this project. It is installed indoors with easy access to overhead cranes and is equipped with a significant amount of instrumentation. Its design is thus uniquely suited to enable Alstom to acquire data, as well as evaluate potential modification necessary.
