Abstract: | The authors introduce the various techniques developed by SIDEM for seawater desalination. Among those techniques the paper presents in detail the vapour compression process by ejectocompression.The ejectocompression process has allowed SIDEM to construct packaged type units with rising maximum capacities : 600 m3/d in 1979, 1,500 m3/d in 1980, 2,600 m3/d in 1981.The authors, as an example, give the main characteristics of 1,500 and 2,600 m3/d units and review their operating experience of this type of plants.A comparison is made with Multiflash units of same capacity namely in terms of investment costs, as well as compactness, reliability, etc. |
