PROJECT INFORMATION

The US-based power company AES operates two CO2 absorption plants located at coal-fired circulating fluidised bed (CFB) units at the Shady Point power station and the Warrior Run power station. Both absorption plants were constructed by ABB Lummus (ABB Lummus Crest licensed the Kerr-McGee MEA technology in 1990).

  • The Shady Point power station is located in Oklahoma and has a gross generation capacity of 360 MW. The plant began operations in 1991. The CO2 recovery plant is located adjacent to the power plant and captures CO2 from a flue gas slipstream. The plant produces over 240 tons of CO2 per day (~70,000-80,000 tonnes per annum) of liquid and solid food-grade CO2.

  • The Warrior Run power station is located in Maryland and has a gross generation capacity of 205 MW. The plant began operations in 2000. The CO2 facility captures CO2 from an extract of ~ 4% of the plant’s flue gas slipstream. The plant produces around 115 tons of CO2 per day (~40,000 tonnes per annum) of beverage grade product.

PROJECT PROPONENTS: E.ON and Fluor

LOCATION: Wilhelmshaven, near Bremen, Germany
 
PROJECT STATUS: Ongoing. The pilot was commissioned in the first half of 2012.
 
CO2 CAPTURE CAPACITY: 70 tonnes per day
 
CO2 CAPTURE SOURCE: Wilhelmshaven 757 MW (net) coal-fired power plant near Bremen

CAPTURE TYPE: Post-combustion capture

CAPTURE METHOD: Absorption chemical solvent-based process (Amine) – the process design of the pilot is based on Fluor’s proprietary Econamine FG PlusSM technology

Project Information

The pilot plant captures CO2 from a side stream of approximately 3.5 MWe from the 757 MW (net) Wilhelmshaven coal-fired power station. The pilot plant is designed to treat a flue gas volume of 19,500 cubic metres per hour, capturing 90 per cent of the CO2 or 70 tonnes of CO2 per day at full capacity. The pilot plant had achieved 4,500 hours of operation through to the first quarter of 2014.

The test program has a number of objectives, including:

  • Demonstrate EFG+ technology on coal flue gas
  • Validate process innovations for energy reduction
  • Test and validate next generation EFG+ solvent
  • Test construction materials selection. 

 The following aspects of the Econamine FG process are being tested:

  • Multi-stage Direct Contact Cooler (DCC)
  • Absorber intercooling
  • Lean vapour recompression
  • Advanced reclaimer configuration
  • Trace component measurements.
