SolveBright™ Post-Combustion CO2 Scrubbing

Regenerable Solvent Absorption Technology

SolveBright™ Post-Combustion CO2 Scrubbing

B&W began initial research of a post-combustion carbon capture process in 2005. This led to the development of the SolveBright™ regenerable solvent absorption technology (RSAT) scrubbing process using an advanced amine solvent with demonstrated superior performance to that of competing solvents at the National Carbon Capture Center.


B&W’s SolveBright scrubbing system is a post-combustion carbon capture technology and works by absorbing CO2 directly from flue gas in an absorber using a regenerable solvent. The CO2-laden solvent is sent to a solvent regenerator where it is heated, and the CO2 is released as a concentrated stream for compression and transport to a CO2 storage facility or for beneficial use. The solvent is then recycled to the absorber for additional CO2 capture.

  • Relative to 30% MEA solutions, our selected solvent demonstrates:
  • Superior resistance to oxidative degradation
  • Superior resistance to thermal degradation
  • Elevated pressure operation
  • Reduced volatility
  • Increased mass transfer rate
  • Reduced regeneration energy

Technology Status

Having completed pilot scale testing, B&W is ready to demonstrate the technology at commercial scale (25 to 75 MWe). A reference plant design at 75 MW is completed based on 90% CO2 capture from a flue gas stream containing 1500 metric tons of CO2 per day.

The reference plant design consists of a full package of engineering documentation, including piping and instrumentation drawings, a three-dimensional plant layout, equipment lists, schematics, preliminary mechanical design and fabrication drawings for major process vessels, foundation and structural steel designs, procurement packages including equipment specifications for all major equipment, construction estimates, engineering man-hour estimates, process flow diagrams, and a complete material and energy balance for the plant.
