✦ Synopsis
A novel distillation system for seawater desalination is presented. It comprises a LiBr-H20 absorption machine and MES, which replaces the condenser and evaporator of the machine. The MES has 20 effects with the top one receiving the steam produced in the generator while the absorber receives the vapor produced in the bottom effect. The system is analyzed over a new record for the evaporation range of 6-63°C. Using a 3000 TR absorption machine, the system showed a yield of 1.53 mgd of fresh water at a GOR of 14.8 and PR of 14.2. In addition, the system provides a cooling effect equivalent to a 220 kW air conditioning unit. The proposed system provides the possibility of operating with a low top brine temperature down to 30°C, which would lead to low cost water and trouble-free long-life operation.
