Development of a Scale-up Tool for Pervaporation Processes
In this study, an engineering tool for the design and optimization of pervaporation processes is developed based on physico-chemical modelling coupled with laboratory/mini-plant experiments. The model incorporates the solution-diffusion-mechanism, polarization effects (concentration and temperature), axial dispersion, pressure drop and the temperature drop in the feed channel due to vaporizatio...
متن کاملPervaporation: Membrane Separations
G-100 is used for higher molecular mass proteins. The solutions of proteins are prepared in guanidine hydrochloride (10 mg mL ), and cytochromec (10 mg mL ) is used as an internal standard. Descending chromatography is carried out at room temperature under an inclination angle of 253 to the horizontal. After 3 h of development the quotient Rs protein/Rs cytochrome c is calculated for each prote...
متن کاملUltrathin Two-dimensional MXene Membrane for Pervaporation Desalination
As a new family of two-dimensional (2D) materials, MXene, with many attractive physicochemical properties, has attracted increasing attentions and been applied for various applications. Here, for the first time, ultrathin MXene membranes with thickness down to several tens of nanometers were developed for pervaporation desalination by stacking synthesized atomic-thin MXene nanosheets. Influence...
متن کاملScale-up Strategies for Membrane-Based Desalination Processes: A Review
Membrane-based technologies have increasingly been chosen in desalination processes, which is evidenced by the increase of large-scale plants constructed in recent years. Indeed, several appropriate strategies should be considered to minimize problems faced during the construction, such as membrane system designs, area requirement, energy requirement, operation and maintenance, and environmenta...
متن کاملNonlinear parameter estimation for solution-diffusion models of membrane pervaporation.
An optimization-based procedure for estimating unknown parameters in solution-diffusion models of membrane pervaporation is presented. Permeation of two components through a polymer membrane is described by distinct solution and diffusion models. The solution model is based on a modified form of Flory-Huggins theory that accounts for interactions between the two penetrants. The diffusion model ...
