### Chapter 3 Separation Processes (Unit operations)

2009-1-10  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
