In recent years old methods of separation are completed by membrane’s processes. Semi permeable membranes utilize as main factor of separation in these processes. Since basically membranes action is often physical separation, there is no thermodynamical limitation dislike of conventional treatment such as distillation, extraction, absorption, adsorption, etc. and just mass transfer resistances exist. Also the processes which have formed upon the variety of membranes are capable to separate materials with different sizes from fluid. In order to get desirable separation, it is essential to estimate amount of membrane modules and also pressure vessels’ quantity and type of their arrangement. In this article four systematic methods has been presented to reply to this requirement; furthermore it is tried that procedure of all methods were simple and easy and possibly without any need to any computer coding. Although all of them can be consider as a computer program.
