Study on CO₂ Capture Performance of Absorbent

This study examines the performance of different single-component organic amines as CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> absorbents. The research employs a CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> absorption experimental system to investigate the CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> capture capacity, absorption rate, and removal efficiency of various amines. The experiment utilizes a mixture of N2 and CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> to simulate flue gas conditions, with a controlled flow rate and temperature. The study compares the performance of primary amines, tertiary amines, and polyamines, focusing on their absorption capacity and kinetics. The results reveal that polyamines, such as DETA and BDA, exhibit superior CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> absorption capacity compared to primary and tertiary amines. Additionally, the research explores the impact of temperature on the absorption process, identifying the optimal temperature range for efficient CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> capture. This study contributes to the understanding of CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> capture mechanisms and provides valuable insights for the development of efficient and cost-effective CCUS technologies.
