The Effect of Feed Steam on MED Dealing with High-Salinity Wastewater

Abstract:

The treatment of high salinity wastewater treatment in refinery has been widely noticed due to more and more stringent laws and regulations. In the paper, in order to deal with the high salinity wastewater efficiently, a MED process was performed, and mathematical modeling was established to discuss the effect of feed steam on MED dealing with high-salinity wastewater. The results indicated that the temperature of steam produced by different low-temperature heat and pressures of the steam could all affect the MED system obviously. For example, the mass of pure water increased slightly with the increase of feed steam temperature in 3 effects system. With the same pressure feed steam, more mass of pure water was produced by fewer effects system, etc. This paper would provide a very useful reference for the high-salinity wastewater reduction via MED process in petroleum refinery.
