Monitoring Amine or Ammonia Based Carbon Sequestration at Power Plants In Real Time Using FTIR Spectroscopy
The MIDAC FTIR Spectrometer Gas Analysis System has been used successfully to detect and quantify agents used in carbon sequestration at power plants using both amine and ammonia processes. This is a fully automated, 10 sample line, turnkey system using FTIR along with other analytical methods integrated by MIDAC's proprietary Autoquant software.
The system is built into an environmentally controlled equipment shelter. Up to 28 more lines can be added. It has been used to measure coal fired combustion gas matrix constituents as well as the efficiency of the CO2 sequestration process itself. The system is robust and able to handle high temperatures, high levels of moisture, and other complicating conditions such as particulates and condensable solids. It has done the critical job of monitoring the loss of CO2 scavenging agent all along the process. It has also measured the effects of other variables such as oxygen, CO2, ammonia, formaldehyde, HF2, and moisture on scavenging agent as well as sampling system bias encountered from reactions and oxidation.
In the search for a commercially viable carbon sequestration process, FTIR spectroscopy is playing a crucial role.
