چکیده

The design of new dual-purpose thermal desalination plants is a combinatory problem because the optimal process configuration strongly depends on desired targets electricity and freshwater. This paper proposes mathematical model for selecting structure, operating conditions, sizes all system components plants. Electricity supposed to be generated by combined-cycle heat power plant (CCHPP) with following candidate structures: (a) one or two gas turbines; (b) additional burners in recovery steam generator; (c) presence missing medium-pressure turbine; (d) generation reheating at low pressure. Freshwater obtained from processes: (e) multi-effect distillation (MED) multi-stage flash (MSF) system. number effects MED stages MSF are also discrete decisions. Different case studies presented show applicability same cost data. proposed powerful tool optimizing (or under modernization) and/or improving existing freshwater production. No articles addressing optimization involving decisions mentioned above found literature.

Cogeneration Power-Desalting Plants Using Gas Turbine Combined Cycle

The gas-steam turbine combined cycle (GTCC) is the preferred power plant type because of its high efficiency and its use of cheap and clean natural gas as fuel. It is also the preferred type in the Arab Gulf countries where it is used as cogeneration power-desalting plant (CPDP). In this chapter, descriptions and analysis of the GTCC components are presented, namely, the gas turbine cycle (comp...
