Separation Processes using Membranes
Membrane separation processes function without heating and therefore use less energy than conventional thermal separation processes such as sublimation or crystallization, distillation. The separation process is purely physical and both fractions (permeate and retentate) can be used. Membrane separation processes can offer many benefits over conventional mass transfer processes. A great number of membrane separation processes are presently being practiced in various segments of industries. Despite the advantages, membrane processes often suffer from shortcomings when used individually. To overcome such limitations, membrane based hybrid processes have been developed to maximize the productivity of the target separation processes.
