In this study, the performance of an irreversible regenerative Brayton cycle is sought through power maximizations using finite-time thermodynamic concept in finite-size components. Optimizations are performed using a genetic algorithm. In order to take into account the finite-time and finite-size concepts in the current problem, a dimensionless mass-flow rate parameter is used to deploy ti...

Based on the benefits of integrated gasification combined cycles (IGCCs), a cogeneration plant for providing electricity and freshwater is proposed. The main novelties devised system are integration biomass regenerative gas turbine with intercooling syngas combustor, where produced in gasifier burned combustion chamber fed to directly. energy discharged from utilized further generation via Kali...

Exergy and thermoeconomic analyses are herein employed to evaluate the proposed refrigeration cycle of Tabriz olefin plant. The exergetic and exergoeconomic variables of all equipment and streams are calculated. Thermoeconomic model is developed according to the total revenue requirement (TRR) method. The results indicate that the rational efficiencies of the Heat Exchanger E-104 and compressor...

This research is concerned with the design and analysis of a geothermal based multi-generation system by applying both conventional and advanced exergy and exergoeconomic concepts. The proposed energy system consists of a dual-organic Rankine cycle (ORC) to vaporize liquefied natural gas (LNG) and produce electricity. A proton exchange membrane(PEM) electrolyzer is employed to produce hydrogen ...

In this paper, an exergoeconomic and exergetic sustainability analysis of a dual-pressure organic Rankine cycle (ORC) vapor compression refrigeration (VCRC) driven by waste heat is performed for power generation cooling production. addition, the most suitable fluid couple among thirty-five different pairs was investigated proposed combined system. The results indicate that highest energy utiliz...

Binary geothermal power plants (GPPs) are mostly encountered in fields with medium and low temperatures. The design operation of dual binary GPPs can be difficult due to the fluid properties. This affects their performance feasibility. Thermoeconomics essential elements for GPPs. In this study, advanced exergoeconomic analysis is applied a true GPP (as case study) further evaluate it from econo...
