Post-Combustion Carbon Capture
Reigning technologies for post-combustion carbon capture and sequestration (CCS) are all based on absorption into solvents of one kind or another.
Proposed solvents include:
- High-strength, corrosion-inhibited MEA (the industry benchmark)
- AMP (2-amino-2-methyl-1-propanol) alone or piperazine-promoted (MHI solvent KS-1™)
- MDEA promoted with piperazine
- Amino acid salts such as sodium glycinate and potassium dimethyl glycinate (BASF)
- Hot potassium carbonate, promoted with piperazine or other amines
- High concentration (40 wt%) piperazine
- Chilled ammonia (Alstom Power)
Pressure drop dictates that large-crimp structured packing will be used in CO2 capture. A 500 MW power station (1/8th the size of the world's largest coal-fired plant) would use 5,000 cubic meters of packing in a 25-m diameter column. And this is not a particularly large plant. Obviously, getting the mass transfer right can make a big difference even in just packing volume and cost. But it's even more important to get the solvent regeneration system right because that's where the bulk of the energy is consumed.
ProTreat simulation is used by many of the leading research groups in CCS and by many of the organizations currently building pilot- and full-scale carbon capture plants. It is the industry standard in this area. ProTreat is the industry's most advanced simulation tool for carbon capture studies. It turns your drawing-board design into a virtual plant.
