Capsol EoP (End-of-Pipe) is a patented post combustion carbon capture technology utilizing the safe and environmentally friendly solvent Hot Potassium Carbonate (HPC) - a method used to remove carbon dioxide from gas mixtures under high pressure (sometimes called carbon scrubbing).
The chemical mixture used in the HPC process is based on potassium carbonate dissolved in water, together with a chemical activator, and a corrosion inhibitor, to decrease the corrosion rate of the material that comes into contact with the fluid.
A pressurized system is essential in the process, since chemical reactions are more efficient under high pressure.
When the pressure increase, the molecules have less space in which they can move, which leads to a higher density of molecules, which in turn increases the number of collisions and speeds up the reaction time.
Capsol EoP is a cost-competitive, energy efficient carbon capture technology. A compact, scalable, flexible, easy to install, stand-alone unit that connects to the flue gas duct just before the stack.
The Capsol EoP unit does not interfere with the parent plant. Hence, there is no need for expensive retrofitting or adjustments of the existing plant.
HPC as absorbent of CO2 is well documented and it is used in thousands of plants globally in multiple industries.
