With Pentair Advanced Amine Technology, CO2 can be captured from any gas stream based on the combustion of fossil fuels, including but not limited to coal, heavy fuel oil-fired steam boilers, and natural gas-fired combustion engines.
Moreover, the technology can be used to capture carbon dioxide from non-power generation sources, like lime kilns.
The capture plants from Pentair are based on high concentrated monoethanolamine (MEA). MEA is a primary amine that reacts readily with carbon dioxide. Since the reaction is purely chemical absorption, it works well with gas streams having low partial CO
2 pressure, as is the case for flue gases.
Once the carbon dioxide is captured in the MEA solution, it is transferred to a stripping system. Here it is again released from the MEA solution by increasing the temperature of the solution to a point where the chemical reaction that took place in the absorber is reversed.
