Dr. YA Hussain 108 Equilibrium Separation Column In Equilibrium Separation processes, two or more coexisting zones are created with preferential distribution of the different components involved in the process in each zone. For example, in distillation a liquid and vapor zones are created and the components are separated in different proportions between these zones. In absorption and stripping, liquid and gas phases are created. In extraction, two liquid phases are created. The zones are assumed to be, as the name implies, in Equilibrium with each other. This means that the temperature, pressure, and phase compositions are all in thermodynamic Equilibrium . Thus, while all Separation processes are essentially a mass transfer process, the Equilibrium assumption cancels out the need for dealing with transfer rates and focuses only on the transfer amounts. Equilibrium Separation processes are usually operated in a counter current configuration in which the two zones are made to flow opposite to each other in a closed vessel (or Column ).
