We explore the applicability of exergy analysis as an evaluation and monitoring tool for the oil and gas processing on … simulated using measured process data. We distinguish between temperature based exergy, pressure based exergy and the mixing … part of the chemical exergy. It is shown that physical exergy in the material streams mainly is pressure based exergy, and …

evaluated by performing an energy and exergy analysis. This facility exploits an end-life oilfield and runs at conditions … which 18–26 MW and about 3–4 MW are in electrical and thermal energy forms. The greatest exergy destruction takes place in …

Exergy-based efficiencies are measures of the thermodynamic perfection of systems and processes. A meaningful … formulation of these performance criteria for petroleum systems is difficult because of (i) the high chemical exergy of … under certain conditions. We suggest an alternative formulation, called the component-by-component exergy efficiency, which …

The oil and gas processing plants of four North Sea offshore platforms are analysed and compared, based on the exergy … analysis method. Sources of exergy destruction and losses are identified and the findings for the different platforms are … efficiency of the processing plant is challenging. The results of the analysis show that 27%–57% of the exergy destruction take …
