摘要

ION has conducted a thoughtful, comprehensive, and successful program in close collaboration with all its partners at CO_2 Technology Centre Mongstad (TCM), located in Mongstad, Norway. CO_2 was successfully captured for extended periods of time from both Combined Heat and Power (CHP) flue gas from a natural gas combined cycled power plant with and without CO_2 recycle, and Residue Fluid Catalytic Cracker (RFCC) flue gas from the adjacent oil refinery with air dilution at slipstream flows of 12 MWe and CO_2 concentrations ranging from 3.6 to 15%. The data gathered on lON's solvent continues to strengthen the development of lON's solvent technology and positive track record in executing on-site test campaigns in highly industrialized settings. The TCM large scale pilot plant was designed for aqueous amine solvents such as mono-ethanolamine (MEA) and has a few flexibilities built in, e.g., flexibility in the absorber packing height (12, 18 or 24 m). However, the facility lacked some necessary process modifications that ION requires to obtain its lowest possible regeneration energy. Throughout the campaign, ION typically captured 85-95% CO_2 from the respective flue gases at a specific reboiler duty of 3.3 MJ/kg CO_2. Inclusion of processes such as a cold-rich bypass and intercooling would allow for lowering the demonstrated specific reboiler duty. The resulting data from the TCM campaign was used to validate the process model (ProTreat®), and, the output of the process model shows a significantly lowering of the specific reboiler duties to under 2.5 MJ/kg CO_2 (1,075 BTU/lb CO_2). When these regeneration energies are factored into the Techno-Economic Analysis, where lON's technology is compared to the DOE-NETL BBS Case 12, which integrates a highly optimized and commercially available CO_2 capture technology, lON's technology shows: 1. 38% incremental reduction in capital cost of CO_2 capture; 2. 28% incremental reduction in annual operating and maintenance costs of CO_2 capture; and 3. $35-44 per tonne of CO_2 capture, which is a 20% to 40% reduction in cost of CO_2 capture. 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 is currently working on several enabling technologies to further improve performance and reduce costs and has recently been awarded a project from the DOE-NETL Carbon Capture Program to design and cost a commercial-scale CO_2 capture unit retrofit at an existing coal-fired power plant.
