An exergoeconomic approach for retrofit of fractionating systems

Energy, 2002
Abstract Based on a three-link model, this paper presents a multi-objective retrofit optimization algorithm that simultaneously takes into account capacity expansions and uses of energy. This approach was successfully applied to retrofit an aromatic fractionation unit.

Exergoeconomic evaluation of a geothermal power plant

International Journal of Exergy, 2014
In this study, exergy and exergoeconomic analyses of the Dora II geothermal power plant (DGPP) with 9.5 MW net power output are carried out by using real thermodynamic and cost data. The exergetic efficiency of this plant is calculated to be 29.6%. The highest exergy destruction rate among the DGPP components occurs in the cooling towers followed by ...

An Approach of Exergoeconomic Analysis of Thermal Systems

Advanced Energy Systems, 1997
Abstract A new approach of the combination of exergetic and economic analysis for the complex energy system has been proposed, that is, a general exergy and the corresponding cost balance equation which can be applied to any component of thermal system have been formulated.

EXERGEOCONOMIC ANALYSIS OF THERMAL SYSTEMS

2007
Publisher Summary In the analysis and design of energy systems, techniques are often used which combine scientific disciplines (mainly thermodynamics) with economic disciplines (mainly cost accounting) to achieve optimum designs. This chapter presents a brief summary of existing analysis techniques, which integrate exergy and economics.

Exergoeconomic optimisation of steam power plant

International Journal of Exergy, 2012
The second law of thermodynamics combined with economics forms a powerful tool for systematic analysis and assessment of energy systems. This paper presents an exergoeconomic optimisation of 50 MW steam turbine power plant associated with a large fertiliser industrial unit through Thermoeconomic Evaluation and Optimisation (TEO) method, and identifies ...

Comparison Between Speco-Based and Functional Exergoeconomic Approaches

Advanced Energy Systems, 2001
Abstract Various exergoeconomic approaches have been developed in the last 20 years. These approaches include the ones by Frangopoulos, Lazzaretto, Tsatsaronis, Valero, von Spakovsky and their co-workers. The paper discusses exergoeconomic approaches based on specific costs (SPECO), thermoeconomic functional analysis (TFA) and ...

Exergoeconomic analysis of an aircraft turbofan engine

International Journal of Exergy, 2009
This study deals with an exergoeconomic analysis of an aircraft turbofan engine utilising the kerosene as fuel. A new parameter is developed to define the thrust cost rate. The cost of exergy destruction, the relative cost difference and the exergoeconomic factor are investigated.

Exergoeconomic Analysis of District Heating Systems

ASME 2009 3rd International Conference on Energy Sustainability, Volume 1, 2009
District heating is a rational way to use fossil fuels for domestic heating (and cooling) in towns, especially if it is joined to a cogenerative production of electricity. The aim of this paper is to propose the use of exergoeconomic procedures for the design and analysis of district heating systems.
