Studies on separation characteristics and pseudo-equilibrium relationship in pervaporation of benzene-cyclohexane mixtures through composite PVA membranes on PAN supports

Sarkhel D, Roy D, Bandyopadhyay M, Bhattacharya P

Batch pervaporation of benzene-cyclohexane mixtures was carried out using a composite membrane-PERVAPO 2200 (Sulzer Cheratech), and the relevant separation characteristics investigated. Separation factor for this system was found to be 60-70. The effects of physico-chemical parameters like initial solute concentration and feed hold-up volume on permeate flux were studied. A new concept of 'pseudo-equilibrium' state in pervaporation was proposed and data of the benzene-cyclohexane system presented. (C) 2002 Elsevier Science B.V. All rights reserved.
