Hybrid membrane-distillation processes

چکیده
This work focuses on modelling, simulation and process analysis of hybrid membrane separations namely on distillation and pervaporation. Such hybrid process can be applied for the separation of multicomponent azeotropic mixtures without the use of entrainer. Its application is illustrated by the separation of a non-ideal ternary mixture of acetone, isopropanol and water. The extended abstract describes the process simulator for pervaporation and vapour permeation. For the stand-alone membrane process the simulation results are in satisfactory agreement with the gained experimental data. A comparison of different model complexities is presented. The process analysis of the hybrid process shows the influence of decisive operational parameters on process performance and the economic potential of the hybrid process.
