Understanding Carbon Capture Technologies and Methods

Carbon capture refers to the technological processes employed to trap carbon dioxide (CO2) emissions produced from the use of fossil fuels in electricity generation and industrial processes, preventing the release of CO2 into the atmosphere. With climate change as a critical global challenge, breaking down carbon capture into various methodologies and technologies is essential for emphasizing its role in mitigating greenhouse gas emissions.

1. Mechanisms of Carbon Capture

1.1 Pre-combustion Capture

Pre-combustion capture involves the removal of CO2 from fossil fuels before combustion. This method is often used in integrated gasification combined cycle (IGCC) plants. Here, coal or natural gas is converted into syngas (a mixture of hydrogen and carbon monoxide). The CO2 is then separated out using a variety of means, typically through chemical absorption using solvents such as amines. The remaining hydrogen can be used for electricity generation or fuel cells, producing water as a byproduct, which makes this method highly efficient.

1.2 Post-combustion Capture

Post-combustion capture is the most common method to retroactively incorporate carbon capture into existing power plants. In this case, CO2 is separated from the flue gases produced after fuel combustion. The typical approach involves using liquid sorbents like monoethanolamine (MEA) that selectively absorb CO2 as the exhaust gases pass through. After the absorption, the CO2-rich solvent is heated to release the CO2, which can be stored underground or utilized for other purposes. This technology is advantageous due to its versatility and retrofitting capabilities.

1.3 Oxy-fuel Combustion

In oxy-fuel combustion, a fuel is burned in pure oxygen instead of air. The process yields a flue gas that consists primarily of CO2 and water vapor, simplifying the capture process. After cooling the gas, water can be condensed and removed. The concentrated CO2 stream can be processed for storage or utilization.
