This final report to DOE/NETL presents all the work and tests performed during ION Engineering?s (ION) carbon dioxide (CO<
sub>
2<
/sub>
) capture pilot test campaign: ?ION Advanced Solvent CO<
sub>
2<
/sub>
Capture Project?. This project is comprised of three budget periods (BP): BP1 ? Design of a 0.6 MWe system, BP2 ? 0.5 MWe National Carbon Capture Center (NCCC) Testing Campaign, and BP3 ? 12 MWe Technology Center at Mongstad (TCM) Testing Campaign.<
/p>
<

The program began in October 2013 and continued until December 2017. The campaign at NCCC, which took place from June to August of 2015, resulted in 1,116 operational hours where ~350 tonnes of CO<
sub>
2<
/sub>
were captured from the 0.5 MWe coal-fired flue gas slipstream. The follow-up campaign at TCM took place from Oct 2016 to April 2017, where 2,775 hours of operation resulted in the capture of 14,820 tonnes of CO<
sub>
2<
/sub>
, which is a cumulative of capturing CO<
sub>
2<
/sub>
from the natural gas-fired Combined Heat and Power (CHP) plant, and a residue fluid catalytic cracker gas (RFCC) from Statoil at Mongstad.<

ION has conducted a thoughtful, comprehensive, and successful program in close collaboration with all its partners. CO<
sub>
2<
/sub>
was successfully removed and captured for extended periods of time using three gas sources (NCCC Coal-fired Power plant, TCM CHP flue gas with and without CO<
sub>
2<
/sub>
recycle, and TCM RFCC flue gas with air dilution) at various slipstream flows ranging from 0.5 MWe to 12 MWe. The data gathered on its solvent continues to strengthen the development of ION?s advanced solvent and positive track record in executing on-site test campaigns in highly industrialized settings. These existing pilot plants do not include the necessary process modifications that ION requires to obtain the lowest possible regeneration energy
processes such as a cold-rich bypass and intercooling, would allow for lowering the demonstrated specific reboiler duty. The resulting data was also used to validate the process model, and, in the absence of testing on a custom test rig specifically designed for ION?s advanced solvent, the results of the process model have shown specific reboiler duties under 2.5 MJ/kg CO<
sub>
2<
/sub>
(1075 BTU/lb CO<
sub>
2<
/sub>
). When these regeneration energies are factored into the Techno-Economic Analysis (TEA), where ION?s technology is compared to the DOE/NETL BBS Case 12, which integrates a highly optimized and commercially available CO<

Throughout pilot testing, ION has confirmed its understanding of process improvements and analytics that will enable successful operation of its advanced solvent at significantly lower L/G circulation rates, packing heights and regeneration energies than MEA. ION has identified routes to further develop its technology and is looking forward to testing a fully optimized solvent and capture system in the near future.<
