CO2 separation technologies: Clean energy solutions for greening environment

• A thorough summary of the performances of various recent carbon dioxide separation technologies (CSTs) is given with their relative applicability, and pros and cons. • The technical readiness level (TRL) and scalability of various CSTs have been addressed. • The discussion includes energy consumption, costs, effectiveness and recovery of various CO 2 separation technologies, which depicts the feasibility and large-scale implementations of each CSTs. Industrialization and population growth have increased fossil fuel use, leading to rising carbon dioxide (CO 2 ) emissions and a greater emphasis on carbon capture technologies, particularly CO 2 separation techniques. Carbon dioxide separation technologies (CSTs) are viable and promising technologies that lower CO 2 emissions from industrial processes and fossil fuel-based power plants. They are essential for fostering a greener future. This paper reviews key CSTs—membrane separation, adsorption, absorption, cryogenic separation, and chemical looping—with emphasis on their applicability, advantages, and limitations. This paper also provides a detailed study of CSTs with their respective operating and maintenance costs, effectiveness, scalability, environmental impact, and promises for future efficiency at the typical temperature, pressure, and composition of flue gases. Furthermore, the challenges associated with incorporating CO 2 separation technologies into the current infrastructure are covered in this study, as well as providing an avenue to improve their performance and feasibility. In conclusion, this paper outlines potential avenues for further study that might spur innovation and hasten the worldwide adoption of CO 2 separation technology.
