Gas Separation
Gas separation is the process of separating different gases from a gas mixture. In space and astronautical engineering, gas separation is a critical process for life support systems, fuel processing, and environmental control. Gas separation can be achieved through various methods such as pressure swing adsorption, membrane separation, cryogenic distillation, and absorption. Pressure swing adsorption is a commonly used method for separating gases in spacecraft as it is a simple and reliable process. Membrane separation is another method that is used for separating gases based on their molecular size. Cryogenic distillation is a process that uses low temperatures to separate gases based on their boiling points. Absorption is a process that uses a liquid solvent to selectively absorb a particular gas. Gas separation is essential for maintaining a safe and habitable environment for astronauts in space.
