The principle of carbon capture technology is primarily to capture carbon dioxide from industrial emissions or the air and then properly store or utilize it. Here is a detailed explanation:
Capture Methods:
Post-combustion Capture: Carbon dioxide is extracted from exhaust gases emitted from factory chimneys using chemical solvents.
Pre-combustion Capture: Carbon dioxide is separated before fuel combustion, for example, through coal gasification technology.
Direct Air Capture: Carbon dioxide is directly extracted from the air using large fans and special materials.
Storage or Utilization:
Underground Storage: Carbon dioxide is stored in abandoned oil fields or salt deposits, sealed for hundreds of years without leakage.
Utilization: Carbon dioxide is compressed into the bubbles used in carbonated beverages or converted into building material raw materials.
