A method of using a system includes injecting a liquid mixture from a reservoir to an upper cell; stirring the liquid mixture in the upper cell using a stirrer; separating a first organic constituent from the liquid mixture by absorbing the first organic constituent of the liquid mixture at a first peripheral section of a membrane thereby causing a retentate comprising a second organic constituent and a solvent to reside in the upper cell; desorbing the first organic constituent of the liquid mixture at a second peripheral section of the membrane to obtain a first organic constituent permeate vapor; receiving the first organic constituent permeate vapor in a third feed line of a lower cell; receiving the retentate in a second feed line of the upper cell; and sending the retentate to the reservoir via the second feed line.
