“…The total pressure drop of the tube-side of the fired heater increases significantly due to a reduction in external tube diameter in the convection section, which is in line with previous studies [27]. It should be mentioned that allowable pressure drop of tube-side is considered1000 kPa [43].…”

Heaters are one of the central parts of natural gas reduction stations using turboexpanders to prevent the formation of hydrate and corrosion failure. This study intends to design a fired heater by applying a combustion sub-model to derive an optimal model for this kind of application. This model is developed to accurately consider all subsections of the fired heater namely radiation, convection, and shield sections, as well as flue gas composition, and its volume. Within this context, a multi-objective optimization is employed to identify the optimal design of the gas-fired heater in the natural gas reduction station for the Ramin power plant case study. The total economic and environmental costs, together with modified exergy efficiency, are selected as objective functions. Multi-criteria-decisionmaking-method is employed on Pareto frontiers optimal curve to suggest the optimal solution. Results show that the developed model can outperform previous models in thermal efficiency with relatively similar costs. Besides, the optimal point in Pareto suggested by the decision-making-method accounts for a higher modified exergy efficiency (1.3%) than the counterpart, which thermal efficiency is regarded as an objective function. At the same time, its total cost remained almost constant. The effects of changes in each of the design parameters on the objective functions are also evaluated.

“…Indeed, Ref. [ 51 ] showed that exergy can be used to determine the efficiency of fired heaters, of which the ATR is a typical example. For many PCI processes, the cyclic nature of the process presents a particularly challenging scenario as feedstocks and products are cycled, recycled, and discarded.…”

Fault detection and isolation (FDI) within the petrochemical industries (PCIs) is largely dominated by statistical techniques. Although a signal-based technique centered on exergy flows within a process plant was proposed, it has only been applied to single process units. The exergy-based scheme has not yet been applied to process plants that feature at least a single recycle stream. The Tennessee Eastman process (TEP) is commonly used as an FDI benchmark process, but due to obfuscation, the TEP cannot be directly implemented in a commercial process simulator. Thus, application of FDI techniques to proprietary processes will require significant investment into the implementation of the FDI scheme. This is a key impediment to the wide-spread comparison of various FDI techniques to non-benchmark processes. In this paper, a gas-to-liquids (GTL) process model is developed in Aspen HYSYS®, and the model’s performance is validated. The exergy-based FDI technique is applied to the GTL process while the process is subjected to carefully selected faults. The selected faults aim to affect several process units, and specifically, the resultant recycle stream of the GTL process is considered. The results indicate that even though the exergy-based technique makes use of fixed thresholds, complete detection and isolation can be achieved for a list of common process faults. This is significant since it shows, for the first time, that the exergy-based FDI scheme can successfully be deployed in processes with recycle streams.

“…Shekarchian et al [22] performed an exergy analysis of the standalone fired heater to investigate the effect of the heat recovery and preheating techniques on the associated penalties and performance efficiency, the results show the heat recovery and preheating techniques can improve the system performance dramatically. Unlike the common fired heater, steam cracking furnace is a special fired heater with a complex heat exchange system and the cracking process.…”

Steam cracking furnace is a high energy-consuming equipment in the ethylene plant. Reducing the exergy destruction and losses associated with the steam cracking furnace can increase the thermodynamic efficiency of the system and thereby reducing energy penalties. This paper aims to quantitatively evaluate thermodynamic performance of an industrial steam cracking furnace through conventional and advanced exergy analysis in order to assess its energy saving potential. A steady state simulation of an industrial steam cracking furnace with a total feed capacity of 12t/h was carried out. The simulation was validated by comparing the model prediction results with the industrial data. The conventional exergy analysis shows that the overall exergy efficiency of the steam cracking furnace is found to be 43.43% and the combustion process in the radiation section exhibits the largest exergy destruction followed by the tube reactors in the radiation section. The advanced exergy analysis shows that the combustion process has the highest unavoidable exergy destruction. Moreover, the tube reactors in the radiation section has the highest avoidable exergy Highlights  Steady state simulation of steam cracking furnace and model validation  Simulation considering interactions among Convection and Radiation sections, and Quench system  Conventional and advanced exergy analysis of a steam cracking furnace  Combustion process in radiation section exhibits highest exergy destruction followed by tube reactors
