Desalination, 2003 Sweeping gas membrane distillation was investigated as a possible technique for desalination by using a shell-and-tube polypropylene membrane module. Humid air was employed as the vapor carrier gas and the feed solution was circulated in counter-current through the lumen side of the membrane module.

Journal of Membrane Science, 2002 A math. model describing a novel sweeping gas membrane distn. (SGMD) configuration is presented and the sepn. of two volatile components from binary mixts. by this membrane process is theor. investigated. SGMD configuration is modified by using a thermostated sweeping gas in order to enhance the driving forces decrease along the module.

Thermal boundary layers in sweeping gas membrane distillation processes
AIChE Journal, 2002 AbstractThe sweeping gas membrane distillation process was analyzed in a plate and frame membrane module, and a method clarifying the contribution of each boundary layer separately was developed. The temperature polarization coefficients of the fluid phases as well as the overall one have been defined, and their effects on the permeate flux were ...

Nature of flow on sweeping gas membrane distillation
Journal of Membrane Science, 2000Abstract The process of sweeping gas membrane distillation (SGMD), with the liquid feed and the sweeping gas counterflowing in a plate and frame membrane module, has been studied. A theoretical model, which was presented in a previous paper and permitted to obtain the temperature profiles inside the fluid phases, has been developed in order to ...

A desalination process through sweeping gas membrane distillation
Desalination, 1987 Abstract A continuous desalinaton process is analyzed, based on a membrane distillation procedure. Both flat and tubular porous hydrophobic membranes are considered. The aqueous solution flows in direct contact with one side of the membrane, while on the other side a sweeping gas flows and strips out water vapour.

Separation and Purification Technology, 2011 Response surface methodology and desirability function approach have been applied for modeling and multi-response optimization of sweeping gas membrane distillation process used for concentration of sucrose aqueous solutions. Response surface models have been developed to predict the permeate flux and the sucrose concentration rate.

Desalination, 2020
Abstract Membrane distillation (MD) has shown promise for desalination of produced water (PW), but there are very few studies reported on the performance of MD with real PW and the characteristics of the fouling and scaling in MD. Among different MD configurations, sweeping gas MD (SGMD) is the least studied configuration.

EXTREME COOLING VIA SWEEPING GAS MEMBRANE DISTILLATION
Proceeding of International Heat Transfer Conference 17, 2023 Thermal desalination processes like membrane distillation (MD) aim to have rapid evaporation rates to provide large quantities of fresh water. These processes, which resemble counterflow-heat exchangers with membranes in the middle, conventionally seek ...
