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 CO2
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.
