A Falling Film Absorber is a type of gas absorption equipment where a liquid solvent flows as a thin film down the surface of vertical tubes or plates, while a gas flows counter-currently or co-currently. It is commonly used in air conditioning, refrigeration, and chemical processing systems where efficient mass transfer is needed with minimal pressure drop. 🔧 Working Principle Liquid Distribution: The absorbent liquid (e.g., lithium bromide solution or water) is introduced at the top and spreads over a vertical surface (usually inside a tube or along a plate) to form a thin falling film under gravity. Gas Introduction: The gas (e.g., refrigerant vapor, ammonia, or other process gases) enters the absorber and flows against or with the liquid film. Absorption Process: As the gas contacts the liquid film, soluble components in the gas (like water vapor or ammonia) are absorbed into the liquid. Heat Removal: Since absorption is exothermic, cooling is usually provided through a chilled wall or circulating cooling fluid to maintain efficiency.
