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 […]
Case Study
A case study of an existing DPPW production plant in Qatar was used in the analysis. The basic configuration of the case study plant is shown in Fig. 46.1. The power production side consists of a compressor (CP), combustion chamber (CC) and a gas turbine (GT), while the water production side is based on the […]
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 […]
Methodology
Modeling is the creation of a simplified representation of a complex system with the goal of providing predictions of the system’s performance measures. Plant models were designed to capture materials flow. Numerical Simulation Numerical simulation modeling for water balance analysis was based on the following equation, after [7]: SCk = SCk-1 + Y, h DK […]
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 […]
