Polymer blend membranes are promising materials that can overcome the major difficulties associated with homopolymer system in the pervaporation process. Polymeric blend membrane is of great interest because it is the most versatile way of achieving materials with new desirable properties and also the least expensive [13]. Polymer blends are considered as physical mixtures of two or more polymers. In polymer blends, the properties are controlled by the microstructure of the blends. Polymer blend membranes are extensively used in the pervaporation membrane field for obtaining high-performance [14], [15], [16], [17], [18] and [19]. High density polyethylene (HDPE)/ethylene propylene diene terpolymer rubber (EPDM) blend membranes possess very good properties. To the best of our knowledge, the use of HDPE/EPDM blend membranes for the pervaporation process has not yet been examined.
The main objective of this work is to develop a new polymer membrane based on the HDPE/EPDM blend for the selective separation of aliphatic hydrocarbons from alkane–acetone mixtures by pervaporation. The alkane/acetone mixture has been chosen to perform a basic study on the pervaporation process using the membrane. The separation efficiency has been evaluated as a function of blend ratio and feed composition.
