Exergoeconomic optimization of the cryogenic cycles used in the Pilot Plant for Tritium and Deuterium Separation

摘要

Increased consumption of natural resources and energy needs has led to development of new energy conversion technologies and concerns for environmental impacts as a result of emissions. Thermoeconomy is more broadly a science of saving natural resources that connects physics, thermodynamics and economics through the second law of thermodynamics. A power station or associated chemical plants are examples of industrial power conversion system consisting of a set of subsystems or processes. These systems interact with the external environment, making external resource consuming, which are then transformed into products. Finally for this transformation the aim is to increase the economic usefulness. The production process of a complex system of energy conversion can be analyzed in terms of economic profitability and efficiency or in terms of resource consumption. An economic analysis can calculate the cost of fuel, investment, operation and maintenance of a power system or individual components, providing information about how cost sharing between the system and its products. On the other hand, thermodynamic analysis can calculate the efficiency of individual processes in functional areas, locates and quantifies the irreversibility, but can not assess their significance in terms of overall production process. The thermoeconomy combine the economic analysis and thermodynamic analysis by the concept of exergy cost and allowing the optimization of power system. This paper presents a study of pilot plant for separation of tritium and deuterium. The exergoeconomic analyze is use in the cryogenic cycles. Products and resources have been identified in cryogenic cycles and after by the exergoeconomic analyze resulted optimal equipment in chosen configuration.
