Description
Summary:In different process industries, central site utility can produce steam at different levels. A central site utility can be coupled with a Desalination plant. In this paper, we seek the optimum integration of a central utility and a Desalination plant. Estimation of cogeneration potential prior to the design of a central utility system is important for setting targets for site fuel demand as well as steam, power, and desalinated production. Total site analysis has been applied to better understanding of the integration process. In this regard, the Total site sink/source profiles and site utility grand composite curves have been demonstrated to find best scenario for integration. Also, an accurate targeting procedure has been used. In the next step, the thermodynamic modeling and exergoeconomic and exergoenvironmental evaluation have been performed. Moreover, the exergoeconomic optimization has been applied to find optimum desalination system working point while it is integrated with central utility. Exergoenvironmental analysis has been obtained by life cycle assessment. A central utility of process plant is used as a case study to illustrate the usefulness of the proposed procedure to find optimum integrated plant. In addition, the cogeneration targeting method has been applied.
