Abstract
A dual-pathway system for COcapture in both acidified and basified streams is provided. The system may be embodied in an off-shore stand-alone facility to allow for the operation of oceanic COcapture to be more efficient and cost effective. Systems maintain high environmental standards by containing all intermediate acidic and alkaline solutions in a closed system so that the effluent discharged back into the ocean is at the similar pH and salinity as the feed oceanwater, with only COremoved. Acid and base produced by an electrodialyzer unit is used to achieve oceanwater decarbonization via gaseous COremoval and solid CaCOprecipitates removal. The system is configured to require the processing of a very small fraction of the total oceanwater intake for the acid-base generation process.
