Abstract:
1. A system for extracting or capturing carbon dioxide from atmospheric air, comprising: adjacent towers each including a front portion, side portions joined with said front portion and extending to end edges, and an open back portion defined between said end edges, said tower portions including front surfaces and back surfaces, said towers positioned so as to define a narrowed passage therebetween; a wet scrubbing mechanism positioned within each open back portion between said end edges, said wet scrubbing mechanism introducing a basic solution to absorb at least a portion of an amount of carbon dioxide contained in atmospheric air flowing through each open back portion thereby forming a carbonate solution; a filter positioned on said back surfaces; adjustable openings defined in side portions of said towers that are adjacent to said narrowed passage, said openings providing a conduit between said front and back surfaces via said filter; a treatment module including a supply of reagent in communication with said carbonate solution for causticizing said carbonate solution; and a regeneration module for hydrating solid components remaining after said treatment module to regenerate a base material included in said basic solution.
