CO2 Emissions Rise by 0.9% Globally, Highlighting Need for Carbon Capture Technology

In a recent study from the Department of Food Processing Technology in Tamil Nadu, India, researchers have found that CO2 emissions from industrial operations and energy combustion rose by 0.9% in 2022, totaling 36.8 gigatons. This increase is attributed to the growing energy demands and industrial activities globally. The study emphasizes the importance of efficient carbon capture technologies, such as pre-combustion, post-combustion, and oxyfuel methods, to mitigate the effects of climate change.

Key Takeaways:

• CO2 emissions from industrial operations and energy combustion rose by 0.9% in 2022, totaling 36.8 gigatons.
• The International Energy Agency's analysis highlights this trend based on authorized national statistics and publicly available information on energy consumption.
• Pre-combustion, post-combustion, and oxyfuel are the fundamental methods of capturing CO2.
• Among these methods, pre-combustion involves transforming fuel into syngas through gasification, followed by CO2 separation using chemical absorption and the Water Gas Shift Reaction.
• Post-combustion technology involves the exhaust gases, while oxyfuel combustion separates CO2 through sulfur removal using ZnO bed and condensation.
• The captured and purified CO2 can be employed in various food industrial applications, including dry ice production and carbonating beverages.
• R. Mahendran and his team have developed a method to capture and purify CO2 for food processing applications, which was peer-reviewed and published in the Journal of Food Process Engineering.

Statistics:

• CO2 emissions from industrial operations and energy combustion rose by 0.9% in 2022, totaling 36.8 gigatons.
• Pre-combustion technology involves a transformation of fuel into syngas through gasification.
• The Water Gas Shift Reaction is a fundamental step in CO2 separation.
• Post-combustion technology involves exhaust gases from fossil fuels.
• Oxyfuel combustion separates CO2 through sulfur removal using ZnO bed and condensation.
• CO2 capture contributes to a sustainable future and can be achieved by reusing emitted CO2 through various purification techniques.
