SolveBright™ Carbon Capture Technology

Solvent-based Post-combustion Carbon Capture

Flexibility in using a wide range of solvents

SolveBright™ Post-Combustion Carbon Capture

B&W’s history with carbon capture began in 1979 when we evaluated oxy-coal combustion for enhanced oil recovery. We began initial research of post-combustion carbon capture processes in 2005. This led to the development of the SolveBright™ regenerable solvent absorption technology scrubbing process which used an advanced amine-based solvent with demonstrated superior performance to that of competing solvents at the National Carbon Capture Center.

Since that time, our design has evolved to allow solvent flexibility to provide solutions which are adapted to customers’ unique applications.


B&W’s SolveBright carbon dioxide (CO2) scrubbing systems are post-combustion carbon capture technologies which work by absorbing CO2 directly from flue gas in an absorber using a regenerable solvent. The CO2-laden solvent is sent to a regenerator where it is heated, and the CO2 is released as a concentrated stream for compression and transport to a CO2 sequestration hub or liquified and used for beneficial purposes. The solvent is then recycled to the absorber for additional CO2 capture.

NCCC Carbon Capture


B&W Technology

Anticipating the need to reduce greenhouse gas emissions, B&W’s efforts in post-combustion carbon capture started in 2005 with extensive laboratory testing. Having completed pilot-scale testing we designed a full-scale commercial carbon capture plant suitable to capture 1500 metric tons of CO2 per day from a flue gas source.

The 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.

B&W can support your small or large-scale post-combustion carbon capture projects, from initial plant surveys and technology evaluation to plant commissioning and start-up.

B&W Support and Commitment

As an open technology integrator for various solvents, B&W can provide support during your complete path of CO2 capture and decarbonization, from project concept and assessment through design, delivery, construction and startup. Our approach to providing solutions is based on our extensive experience and strong technology knowledge in overall plant integration, including:

  • Pilot or small-scale units to support Front-End Engineering Design (FEED) studies
  • Review and evaluation of alternative project approaches
  • Project scheduling to meet key milestones
  • Complete documentation packaging
  • Design, supply and integration of flue gas pre-treatment systems to optimize operating conditions of the entire carbon capture plant



Flue Gas Pre-Treatment for Post-Combustion Carbon Capture

Solvent-based scrubbing technologies often require reductions in various constituents found in the incoming flue gas. Flue gas pre-treatment is important for the scrubbing process to result in optimum effectiveness of the carbon capture technology. Additionally, project economics are improved by ensuring optimum flue gas conditions entering the system, including reduced moisture and pollutants, and favorable temperature range.

B&W’s proven and industry leading emissions control solutions can be integrated into your carbon capture system for optimized flue gas conditions.
