Results and Discussion

Production—Demand Ratios Numerical simulation was used to determine the relationship between total water or power demand and total water or power produced. To minimize the per unit cost of electricity production and water desalination, two important selections must be ac­counted for at a certain time interval: namely, electricity and water demands. In or­der to satisfy […]

Simulation Experiments

In the power and water production simulation experiments, a quasi-experimental design was used [10]. This approach focuses on comparing the results of the cur­rent situation (control experiment) with “what-if ’ scenarios. In the case study plant, power generation is driven by gas turbines and thermal energy from their exhaust is used to generate low-to-medium pressure […]

Simulation Modeling

Simulation modeling is a common method for analyzing complex systems. It cre­ates a simplified representation of a system under study. Then one can start experi­menting with the system, keeping in mind prescribed set of goals, such as improved system design, cost-benefit analysis, and sensitivity to design parameters. Experi­mentation consists of generating system scenarios and observing […]

Simulation, Modeling and Analysis of Water/ Power Ratios for a Dual Purpose Water and Power Production Plant

Luma M. Diab and Farayi Musharavati Abstract In dual purpose power and water (DPPW) production plants two chal­lenges are often encountered; (a) maintaining operations that meet a desired water production/demand ratio or power production/demand ratio, and (b) meeting the desired water to power ratio. Although these problems are usually implied in the implemented plant design […]

Concluding Remarks

In this study, the importance of power/water cogeneration plants as alternative and cost effective means of providing both water and power simultaneously has been discussed. It is generally believed that power/water cogeneration plants have the potential to drastically reduce the unit costs of freshwater and power. Consequently, a number of thermodynamic and thermo-economic investigations on […]
