    Enhanced exergetic analysis of an olive oil refining plant: evaluation of the first and second level of exergy destructions
    (Inderscience Enterprises Ltd, 2019) Bozoglan, Elif; Erbay, Zafer; Hepbasli, Arif; Gunerhan, Huseyin
    Enhanced exergy analysis is built up as a novel modality to specify the origins of irreversibilities and to concentrate substantial improvement potential of components. The scope of this paper is to apply the enhanced exergy analysis to an olive oil refinery plant operated in Izmir, Turkey, that is conducted for the first time to agree the first level (endogenous/exogenous) and the second level (combination of the endogenous/exogenous and unavoidable/avoidable parts studied before) of destructions for exposing substantial efficiencies. Results showed that the components in the plant mostly have endogenous exergy destructions. Besides, the distillation unit has the highest endogenous exergy destruction value of 150.9 kW as the avoidable and unavoidable endogenous sections are 76.85 and 74.08 kW, respectively. Furthermore, the shell and tube economiser has the highest modified (enhanced) exergetic efficiency of 99.9% while the modified performances of plate-heat exchanger and pump (VII) are calculated as 73% and 71.24%, respectively.

    Splitting the exergy destructions of an olive oil refining plant into avoidable and unavoidable parts based on actual operational data
    (Inderscience Enterprises Ltd, 2016) Bozoglan, Elif; Erbay, Zafer; Hepbasli, Arif; Gunerhan, Huseyin
    This study focused on assessing the performance of an olive oil refinery plant (with an oil capacity of 5595 kg/h) located in Izmir, Turkey. The analysis was performed with the use of actual operational data of the system components while an advanced exergy analysis method was used. By this way, unavoidable and avoidable destructions of olive oil refinery plant components were obtained. The results indicated that the greater part of the exergy destructions detected in the system were avoidable and could be minimised by improvements in the design. The highest exergy destruction rate (217.96 kW) was determined owing to the distillation unit of the system with a markedly high unavoidable exergy destruction ratio of 50.92%. In addition, the efficiencies of the components in the plant varied from 5.67% to 90.7% while their corresponding modified exergetic efficiencies were in the range of 8.74% and 92.48%.
