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
B&W SolveBright™ Advantages
With more than 50 years of experience with flue gas treatment systems, we understand the challenges of integrating post-combustion capture technologies into a plant.
- 15+ years developing post-combustion carbon capture solutions, and we understand the process and the equipment
- B&W has a well-developed and rigorously tested solvent as well as experience with a wide range of solvents
- Experience across a wide range of industries with varying fuels
- Reference plant design is ready for commercial demonstration
- Global presence will be advantageous in supporting a wide range of customers regardless of location
- Experienced with thermal management associated with combined heat and power systems
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.
