Abstract:
A flexible pervaporation module was developed and characterized. The spacers it uses allows the volume of the donor and/or acceptor to be altered as required. The performance of the module was tested as regards both dynamic behaviour and continuous pervaporation in terms of flow-rates, temperature, type of membrane, flow mode, etc. A method for the determination of ethanol in different types of wine was developed and applied to various samples in order to validate the proposed continuous separation approach.
