, 2015 This chapter describes the fundamentals and applications of pervaporation as an advanced, energy-intensive separation system. Pervaporation has been developed in the 1980s and has by now matured as a state-of-the-art technology, particularly in some ...

Pervaporation as an Alternative to Headspace
Analytical Chemistry, 1997The use of pervaporation as an alternative to headspace is proposed. The analytical system involves the speciation of organomercury compounds in solid samples using pervaporation, which has been coupled for the first time to gas chromatography. The speciation of mercury as Me(2)Hg, Et(2)Hg, and MeHgCl has been carried out without any derivatization of ...

Pervaporation with Latex Membranes: A Study on Membrane and Pervaporation Effects
Separation Science and Technology, 1995Abstract The separation process is affected by a number of factors related to the membrane itself and the operation conditions. For latex membrane systems, factors such as feed concentration and feed temperature are found to affect pervaporation properties similarly to solvent-cast membrane systems.

The Use of Pervaporation in Biotechnology
1993One of the major problems in modern industrial scale biotechnology is the separation, concentration and purification of the bioreaction products. This mass separation task, generally referred to as ‘downstream processing’, is often particularly difficult.

Enantioenrichment by pervaporation
Journal of Membrane Science, 2004The present paper describes an original concept of membrane-assisted enantiomer enrichment exploiting a combination of complexation to β-cyclodextrin and selective transport through a PDMS pervaporation membrane. Linalool has been used as a model racemic mixture, due to its large use in perfumes, soaps and detergents. Results, under different operating

Journal of Membrane Science, 1990
Abstract The appearance of a variety of membrane processes to treat liquid mixtures has given rise to an extensive, if not altogether consistent, terminology. Although a clear denotation of the process variants is wanted, there seems to be no need to create new terms.

Separation of IPA/water mixtures by pervaporation: sorption and pervaporation results
Vacuum, 2003Homogeneous membranes were prepared by blending polyvinyl alcohol (PVA) with polyacrylic acid (PAA) and furthermore the blend membrane is cross-linked covalently through an ester linkage formation between a hydroxyl group of PVA and carboxyl group of PAA. These membranes were evaluated for separation of azeotropic isopropyl alcohol (IPA)/water mixtures

Pervaporation in Biotechnology
1991Membranes and membrane processes are now receiving increasing attention as efficient tools in modern industrial-scale biotechnology for the separation concentration and purification of bioreaction products. The growing use of membranes particularly in downstream processing can be attributed to several process-related properties which make them ...
