According to an analysis by the Earth System Research Laboratories of the National Ocean and Atmospheric Administration (NOAA),CO 2 emissions are rising quickly worldwide, and the atmospheric concentration of CO 2 has gotten close to a new high of 441 parts per million. The negative effects of climate change are closely related to the rising atmospheric concentration of CO 2 brought on by the world's expanding CO 2 emissions. The development of carbon capture technology offers a temporary way to lower CO 2 emissions by capturing and separating the gas from both the atmosphere and point sources of emission. Conventional CO 2 capture methods including chemical absorption, cryogenic separation, and pressure swing adsorption have been used extensively, but they frequently have high energy costs, complicated operations, and negative environmental effects. Membrane technology has become a viable substitute in recent years because of its ease of use, adaptability, and energy efficiency. It has come out as a favourable solution for CO 2 sequestration and is currently being investigated for removal of CO 2 from power plant emissions due to the fundamental engineering and cost effectiveness over challenging separation techniques. This work examines how the addition of metal salts, particularly calcium and magnesium salts, affects the ability of cellulose acetate (CA) membranes to separate gases. Improving the membranes' CO₂ permeability for industrial-scale gas separation is the goal. The CO₂ permeability of CA-metal salt hybrid membranes was carefully assessed after they were constructed and described. The key aim of this study framework is to analyse the impact of Metal salts on CO 2 sequestration performance from stream gas. Cellulose Acetate membranes are fabricated with Inorganic (metal) salts (ZnCl 2 and CaCl 2 ) of different compositions. Physical appearance, structural and compositional characteristics of the synthesized membrane is confirmed by using characterization techniques like FTIR, SEM and XRD. Gas permeation performance is tested by using single stage gas permeation test cell. The result demonstrated that the membrane fabricated with CaCl 2 salt showed a satisfactory CO 2 removal efficiency as compared to pristine cellulose acetate and other CA-metal salt hybrid membranes proving to be more potential applicant for future applications in CO 2 capturing.
