Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

This document examines the experimental application of the gas scavenging membrane distillation (SGMD) process and its advantages and disadvantages. SGMD is the least used configuration in membrane distillation (MD), and it is more expensive to build. Scavenging Gas Membrane Distillation (SGMD) is used to treat complicated solutions with volatile molecules to separate. In this study, heat and mass transport mechanisms, as well as modeling and simulation studies, are systematically reviewed. In SGMD, the main operating parameters are supply temperature, supply flow rate, gas temperature, and gas flow rate. Furthermore, the performance of SGMD is discussed and highlighted. Potential applications and areas in which SGMD could excel are mentioned. Finally, future research opportunities in SGMD are identified. A hollow fiber scavenging gas membrane distillation (SGMD) module is examined in this study. Our SGMD distillation unit has been modeled by mathematical equations and simulated by a runtime program on Matlab software to evaluate the effects of heat transfer and mass transfer. Also, we have found that the heat and mass transfer in our SGMD desalination system is defined by the temperature evolution in the vaporization chamber and the inert gas velocity of the gas. The model predicts a small error of 3.6% with the experimental data reported in the literature, indicating the reliability of simulated results
