CARBON DIOXIDE CAPTURE AND RELATED PROCESSES

摘要

Processes for capturing carbon dioxide are described. The carbon dioxide may be captured from the atmosphere and/or from the waste stream of a carbon dioxide point source (e.g., power plants, chemical plants, natural gas fields, oil fields, industrial sites, etc.). The processes can involve capturing carbon dioxide using alkaline solutions (e.g., NaOH). In some processes, the carbon dioxide may react with the alkaline solution to form a product (e.g., NaHCO 3 ). The alkaline solution may be made a number of different ways. In some of the processes, products produced during processing may be used to add value beyond carbon dioxide capture.
