The paper presents the focuses of application in membrane processes for the desalination of brackish water or salt water using the sweeping gas membrane distillation (SGMD); at first, it is the least used configuration of MD, and the design of this system is arduous and very expensive, and it is used to treat solutions containing non-volatile compounds, such us salts which is totally rejected, and high purity of water was recuperated. Vapor transfer is an important thermally induced phenomenon in the membrane-by-membrane (MD) evaporation and condensation. Our SGMD distillation system was simulated using MATLAB programmers on heat and mass transfer aspects. In our research, we found that heat and mass transfer in the SGMD is determined by the evaporation temperature of the gas and the sweep rate. The operational parameter (fluid velocity) is influenced across the layer on both sides of the membrane, because it is the source of the transfer of heat and mass in many membrane processes.

单元吹扫气膜蒸馏的设计：膜和运行参数的实验研究

本文介绍了在膜工艺中使用吹扫气膜蒸馏（SGMD）进行微咸水或盐水脱盐的应用重点。首先，它是MD最少使用的配置，并且该系统的设计艰巨且非常昂贵，并且用于处理包含非挥发性化合物（例如被完全排除的盐）和高纯度水的溶液恢复了。蒸气传递是膜-膜（MD）蒸发和冷凝过程中的一种重要的热诱导现象。我们的SGMD蒸馏系统是使用MATLAB程序员在传热和传质方面进行仿真的。在我们的研究中，我们发现SGMD中的传热和传质是由气体的蒸发温度和吹扫速率决定的。
