  "patent_number": "US 20220203297",
  "country": "US",
  "title": "Capturing Carbon Dioxide While Making Industrial Materials",
  "original_title": "Systems and methods for carbon capture",
  "summary": "This patent describes a system and method for capturing carbon dioxide released during industrial processes like making cement or steel, while also producing useful materials and recovering energy.",
  "what_it_does": "The patent outlines a system for capturing carbon dioxide (CO2) from processes that heat carbonate-containing raw materials, such as limestone. A reactor heats the raw material with an oxidant, creating a decomposition stream of solids and CO2 gas (Claim 1). A separator then splits this stream into a gas stream (with CO2) and a solids stream. A heat exchange unit cools these streams, recovering energy. Finally, a CO2 separation unit purifies the cooled gas, creating a CO2-rich stream for capture and a CO2-lean stream. For example, this system can be integrated with a cement plant to capture CO2 released during clinker production (Claim 13) or with a steel-making plant (Claim 16).",
  "what_it_does_not_cover": [
    "Does not cover carbon capture methods that do not involve heating a carbonate-containing raw material (calcination).",
    "Does not cover systems that capture CO2 from sources other than the decomposition stream, such as general combustion flue gases not from calcination.",
    "Does not cover systems that lack a dedicated heat exchange unit to cool the gas and solids streams for energy recovery.",
    "Does not cover systems where the CO2 is not separated into distinct 'lean' and 'rich' streams.",
    "Does not cover carbon capture processes that are not integrated with the production of industrially useful materials or power generation as described."

  "abstract": "The present disclosure provides systems for carbon capture in combination with production of one or more industrially useful materials. The disclosure also provides methods for carrying out carbon capture in combination with an industrial process. In particular, carbon capture can include carrying out calcination in a reactor, separation of carbon dioxide rich flue gases from industrially useful products, and capture of at least a portion of the carbon dioxide for sequestration of other use, such as enhanced oil recovery.",
