Soda lime is widely used in closed breathing environments, such as submarines and spacecraft, to absorb carbon dioxide exhaled by individuals, ensuring the air remains breathable. In medical settings, it is utilized in anesthesia machines to remove CO2 from the exhaled gases of patients, allowing the safe reuse of anesthetic gases. Additionally, it is employed in laboratories for gas purification processes, particularly in experiments requiring the removal of carbon dioxide from gas mixtures. Its ability to absorb moisture also makes it useful in drying applications in various industrial processes.
