Membranes for Carbon Dioxide Separation on a Small Scale: State of Art, Challenges and Applications

Out of all the gases that are present in our atmosphere, carbon dioxide accounts for only 0.04% of the total. In the current times, carbon dioxide is known to be one of the gases having an upper hand in contributing to an increase in the pollution level through the greenhouse effect. The exponential increase in technology and industrialization are the main source of carbon dioxide in the air [1]. Moreover, technological advancement also demands having sustainable ways to overcome the by-products of the processes to maintain a steady balance between our surroundings and technological growth [2]. This study reviews research papers that explain putative small-scale methods of carbon dioxide extraction from air of a specific volume. It will help the reader carry out the process in their daily lives. Many patients, for example, are kept inside a closed chamber in hospitals. In addition, in convention halls, a large number of people congregate in a small space. As a result, it is critical to identify ways to maintain carbon dioxide levels under control in such cases.
