The separation of azeotropic mixtures is often energy intensive, thus process intensification (PI) becomes an attractive route to enhance efficiency. Two the most commonly used intensifications are dividing wall columns and hybrid distillation-membrane processes. In this work, three typical distillation structures, followed by pervaporation (D-P), (P-D), then (D-P-D), considered compared with a...

This paper presents a complete dynamic modeling of a membrane distillation process. The model contains two consistent dynamic models. A 2D advection-diffusion equation for modeling the whole process and a modified heat equation for modeling the membrane itself. The complete model describes the temperature diffusion phenomenon across the feed, membrane, permeate containers and boundary layers of...

Hybrid separation systems have recently been hailed as one of the inost promising alternatives to conventional capital and energy intensive separation processes. Hybrid separation systems are able to effectively separate inixtures commonly encountered in the fine chemical and pharmaceutical industries that are difficult or impossible to separate by conventional distillation processes due to aze...

In recent decades, membrane-based processes have been extensively applied to a wide range of industrial processes, including gas separation, food industry, drug purification, and wastewater treatment. Membrane distillation is thermally driven separation process, in which only vapour molecules transfer through microporous hydrophobic membrane. At the operational level, performance membrane negat...
