Chapter 3 Separation Processes (Unit operations)
The equilibrium concentration represents the maximum extent a separation process can reach. The thermodynamic basis for achieving separation is that all matters in nature have the tendency to reach equilibrium. The driving force for separation of a component from the original mixture to another phase is the difference between the initial/actual concentration and the equilibrium concentration. For example, two well-known equilibrium relationships are Rauolt''s law for vapor-liquid equilibrium used in distillation, Henry''s law for gas-liquid equilibrium …
