In this paper, a new thermodynamic cycle for power and fresh water production is presented, which includes MED-TVC desalinations and Allam cycles due to the important influence they have on the electric power industry in controlling and limiting greenhouse emissions. First, the Allam cycle analyzed and the appropriate location for heat-extraction identified to produce the required water vapor for the desalination system. It was determined that the heat site suitable for use in the desalination cycle is the heat from the outlet of the Compressor, which is estimated as 100 MW. The MED-TVC Desalination, one of the most suitable and most economical desalination, is used to combine the Allam cycle and desalination in the Kish district, located in the south of Iran. The proposed cycle is analyzed from the perspective of energy and exergy. The results show, the highest amount of exergy used to generate power in turbine and the amount of produced freshwater increase with increasing the capacity of Turbine. For this purpose genetic algorithm is used in two different scenarios to minimize and maximize the exergy destruction and produced fresh water respectively. The optimization of the system with genetic algorithm led to 18% decrease in total exergy destruction of the cycle in the first scenario and 7% decrease in the second optimization scenario. Furthermore, the efficiency of the cycle in first scenario and second scenario increased by 30% and 13% respectively. In the scenario optimization scheme, the amount of fresh water increased by 22%.

“…Integrating a MED desalination unit by a combined-cycle dual-purpose plant was estimated by Chacartegui et al (2009). They utilized the stationary lumped volume approach and reported different numerical and qualitative results to combine the combined cycle with desalinated water production [7]. Li et al (2012) studied an innovative hybrid of power and desalination units.…”

Solar energy is one of the most promising strategies to reduce energy consumption and emissions pollutions. In this paper, integrating a combined cycle power plant with a Solar Parabolic Trough Collector (PTC) is evaluated and investigated. In this regard, Qom Combined Cycle Power Plant is considered a real case study in Qom city. Energy, Exergy, Exergoeconomic, Exergoenvironment, Emergoeconomic, and Emergoenvironemntal Analysis as (6E) Analysis have been performed to understand the base plant's integration better. Environmental impacts have been calculated by Life Cycle Assessment (LCA) in Sima Pro Software. Also, computer code has been developed for 6E analysis of base and integrated power plants. Validation of thermodynamic simulation has been examined with Thermoflex Software and plant data. Energy analysis results show the power output of the steam plant and overall energy efficiency is increased to 7.14% and 4.44% rather than the base case without adding additional fossil fuel. It shows the power generation and energy efficiency are increased significantly by adding PTC. Also, the overall exergy destruction and the total exergy cost rates are raised to 7% and 11.27%. In addition, overall environmental impacts, overall emergoeconomic, and overall emergoenvironmental values are increased to 1.67%, 6.2%, and 15.4%, respectively. However, the overall environmental impacts per net power are decreased.

“…To overcome the scarcity of power and fresh water, thermal desalination plants are usually integrated as a dual-purpose scheme for simultaneous production of power and fresh water, which increases the thermal efficiency of the plant as compared to a stand-alone thermal desalination plant . Numerous studies ,− have conducted thermodynamic modeling and cost optimization for power and fresh water generation systems. Janghorban Esfahani et al have developed mathematical and economic models for a multieffect thermal–vapor–compression (METVC) system and optimized METVC system based on minimization of unit product cost and maximization of gain output ratio and fresh water production simultaneously.…”

In this Article, a systematic approach of cost analysis and optimization for combining the multieffect thermal vapor compression (METVC) desalination system with the gas turbine power plant (GT) was proposed on the basis of thermodynamic, economic, and environmental attributes. The total annual cost (TAC) of the combined system, including annual capital and operating costs, was modified to define an efficient cost objective function by adding the exergy destruction cost as a lost opportunity cost, and environmental emissions cost as a damage cost of the system to the operating cost. A parametric analysis was conducted to evaluate the effects of the key thermodynamic parameters for combining the GT and METVC systems, including the gas turbine inlet temperature (TIT), the HRSG outlet temperature (HOT), and the temperature difference between the effects of the METVC system (ΔT METVC ) on the modified total annual cost (MTAC). The parameter optimization was achieved using a genetic algorithm (GA) to find the optimal key thermodynamic parameters with minimization of the MTAC of the combined system. In addition, the methodology was applied to optimize the combining of a METVC desalination system with a GT power plant located in Mahshar, Iran. The optimization results indicated that the METVC systems with less than five effects cannot be combined with the current GT power plant because the combined systems cannot produce the power and fresh water requirements. Among the combined systems with more than four effects in the METVC system, the combined system with five effects in the METVC system was selected as the best system, which can produce 28 543 m 3 /day fresh water and 127 MW power, respectively, and reduce the NO x emission by 3.6% as compared to the current power plant.
