Abstract
Membrane distillation (MD) is receiving recent attention as a technique to efficiently concentrate aqueous solution such as seawater. It has potential benefits of low temperature and pressure operation with high degrees of separation. In this work, the effect of the membrane thickness was studied to produce of the steam flow in the three different mass transfer mechanisms, and in the different possible combinations of its mechanisms in three different temperatures. The results have been carried using a polynomial approximation through MATLAB. A quite important increase in the flow in the model (DGM, Schofield, and KMPT) was observed with a decrease in the stream rating in the model (KMT). However, the Molecular model, DGM model, KMPT model, and Schofield model are not affected by the membrane’s thickness. After, we have studied the effect of this parameter (Thickness of the membrane) on the transfer of conduction heat and latent heat.
Highlights
In the early of 1980 with the growth of membrane engineering, Membrane distillation (MD) claims to be a cost effective separation process that can utilize low-grade waste and alternative energy sources such as solar and geothermal energy [1]
Air gap membrane distillation (AGMD) in which an air layer is interposed between the membrane and the condensation surface [6,7]
When the temperature is fixed at three different temperatures and the membrane thickness is swept between [1.10-4, 10.10-4] m, following results are observed: Prior to undertaking detailed presentation and discussion of the new results obtained in this study, Figure 2 shows the variation of the vapor of Knudsen diffusion as function of the membrane thickness in three different temperature
