System and method for carbon dioxide capture and sequestration

A method capable of capturing carbon dioxide from ambient air under ambient conditions, the method comprising the steps of:

• providing energy to a primary production process which produces a primary product with co-generated usable process heat, applying the co-generated process heat from said primary process to generate process heat steam superheated at ambient pressure,
• utilizing a plurality of parallel combined stages, alternately repeatedly exposing a sorbent in each of the parallel combined stages, to parallel capturing and stripping/regeneration system stages, each of the parallel stages comprising:
• initially admixing a minor quantity of treated effluent gases with a substantially larger quantity of ambient air flow to form an ambient air-effluent gas mixture containing a minor quantity of the effluent gases;
• during each of the parallel capture stages, exposing said sorbent to a flow of the ambient air-effluent gas mixture, so as to enable said sorbent to capture carbon dioxide from said ambient air and form CO2-laden sorbent, and
• during each of the parallel stripping/regeneration phases, in parallel sealed regeneration chambers containing the CO2-laden sorbent, withdrawing air or any other gas entering the sealed regeneration chamber with the CO2-laden sorbent to form at least a partial vacuum, passing the process heat steam into the sealed regeneration chamber and exposing said CO2-laden sorbent to said process heat steam, so as to cause the stripping of such captured carbon dioxide from the sorbent, resulting in a regenerated sorbent, and forming a carbon dioxide/water exiting mixture from each of the parallel sealed regeneration chambers.
