THERMAL CYCLE AND FINANCIAL MODELING FOR THE OPTIMIZATION OF DUAL-PURPOSE POWER-CUM-DESALINATION PLANTS

Integrated thermal cycle models, which have been developed for the sim ulation of dual-purpose power/desalination plants, are described. The models are used to determine net station heat rates and energy require ments for the desalination plant with multistage flash (MSF), low-temp erature multiple-effect distillation (LTMED) and reverse osmosis (RO) as the process options. A financial model is used to establish the cos t economics of the integrated plant and to determine power and water c osts based on a classical method of cost allocation in dual-purpose fa cilities.
