ION - Model ALAS -Advanced Liquid Absorption System
ION’s Advanced Liquid Absorption System (ALAS) has been demonstrated in both small and large-scale commercial testing facilities and has consistently outperformed the industry standard MEA solvent in post-combustion capture efficiency. Based upon an independent techno-economic-analysis (TEA) performed by Sargent & Lundy, during which ION’s ALAS was compared to MEA (the current industry standard solvent), ION’s system demonstrated a 38% reduction in incremental capital costs and a 28% reduction in the incremental annual operating and maintenance costs, resulting in a total cost of CO2 capture between $39 – $45/tonne. ION’s ALAS does not require a unique process to function at full capacity. It uses capture processes that have existed for decades, which makes it easily scalable for larger commercial projects.
Production
Fuel for the power plant is burned in the boiler. Steam from the fuel drives the turbines that power the facility. CO2 is emitted during the production process and released into the environment if there is no carbon capture process in place.
Absorption
Flue gas rich with CO2 is directed into an absorption tower. ION’s Advanced Liquid Absorbent contacts the CO2-heavy flue gas and absorbs the CO2. Flue gas, now free of CO2, is returned to the stack and safely and cleanly released into the atmosphere.
Regeneration
The ION absorbent, now loaded with CO2 (“rich solvent”) is directed to the regeneration section of the process. The Liquid Absorbent is then heated, which strips our the CO2. The captured CO2 is then sent to be compressed and transported for utilization in a variety of industries or for permanent sequestration.
