“…Further development is required in order to optimize the performance of thermocompressor in the area of design and performance. For example, efficiency of the MED-TVC unit can be affected by changing the location of thermo-compressor suction [67]. Higher efficiency in terms of energy consumption, operation, and maintenance cost and reliability should be the major goal in the designing of a desalination plant.…”

Desalination has now become one of the major water treatment processes in several countries around the world where shortage of water is a serious problem. Energy consumption is a vital economic factor in selecting the type of desalination processes because current desalination processes require large amount of energy which is costly. Multi-effect desalination system with thermal vapor compression (MED-TVC) is particularly more attractive than other thermal desalination systems due to its low energy consumption. MED-TVC is characterized by high performance ratio, easier operation, low maintenance requirements and simple geometry. These attractive features make MED-TVC highly competitive to other well-established desalination techniques that include the reverse osmosis and multi-stage flash desalination. The primary goal of this paper is to present a preview of some aspects related with the theory of the technology, parametric study of the MED-TVC systems and its development. It will analyze the current and future aspects of the MED-TVC technology in view of latest installed plants.

“…The response surface has even been combined with genetic algorithms and neural networks to determine the optimization of annual energy costs (Janghorban Esfahani et al, 2012). Studies reported on evaporation using thermocompression include desalination of water where the position of the thermo-compressor has been analysed (Kouhikamali et al, 2011) and the operating conditions of a horizontal tube evaporator (Kamali et al, 2008(Kamali et al, , 2009. For the processing of foodstuffs, a single effect multi-objective optimization has been proposed (Sharma et al, 2011).…”

“…The TVC performance improves as the motive steam pressures increases. On the other hand, Kouhikamali et al, 29 focused on the effect of changing the location of TVC on the system performance, and reported that altering the suction pressure of entrained vapor in the TVC has affected the entrainment ratio significantly. Similar studies on preferred location of TVC in MED‐TVC system were carried out by other investigators 30,31 …”

This work focuses on reducing the energy needed to desalinate seawater through novel integration of MSF system with a thermal vapor compressor (TVC). The analysis extends to investigate positioning the TVC in different locations to find the most suitable location for TVC connection. Two different configurations of TVC's integration to MSF (single or double TVC's with MSF system) are proposed. Analytical models for brine recirculation MSF and MSF-TVC have been established and validated against real plant data where a very good agreement was attained for important process parameters. Results show a significant improvement in thermal performance ratio (from 8.58 to 12.96) for the MSF-TVC, while the steam consumption has also been reduced by 33%.Entrained vapor by TVC from a selected stage adversely affects the heat recovery of the recirculating brine, which drops the top brine temperature (TBT) by about 3 C. This resulted in a decrease in the productivity that is rectified by increasing the rate of brine recirculation to maintain the same desalinated water productivity. Energy analysis revealed a significant drop of about 34% in cooling seawater, which partly leads to energy saving of about 16%. Therefore, the proposed MSF-TVC system shows higher thermal performance ratio, a decrease in the required heat transfer area, and reduction in the required energy per unit mass of pure water produced. Moreover, since the TVC requires higher motive steam pressure, this implies smaller steam pipe diameter. The effect on the integrated power plant load changes is also considered.
