“…Energy analysis is an important approach to understand any process and optimizing the overall energy consumption. Various energy analysis works through modelling and optimization of various real-life industry case studies have been conducted by several researchers (Hoseinzadeh et al, 2019, Kariman et al, 2019, Hoseinzadeh et al, 2020, Hoseinzadeh et al, 2020(b)). Typically, for the conventional distillation arrangements energy integration method has been used to reduce energy costs (Shahruddin et al, 2019).…”

In this work, a non-conventional distillation sequence with thermal coupling (Petlyuk Column) was presented as a technique to perform the separation of the NGL consist of ethane, propane, butane or other higher alkanes. The improvements were investigated through the energy analysis and remixing effect. From the result obtained, it was found that the Petlyuk arrangement consumes less amount of energy and able to reduce the remixing effects as compared to the conventional column sequencing. The Petlyuk arrangement saved about 44.49% and 12.83% in terms of cooling and heating duty, respectively. The overall annual energy saving shown by this arrangement is 39.22%. This arrangement proved to be able to prevent the remixing effect occurrence that contributes to thermal and separation inefficiency. The desired separation efficiency also obtained by this arrangement as all the product specifications are met. The ability in avoiding remixing effect by the Petlyuk column permits a significant reduction in CO2 emission with an average of 29.43 % of each equipment involved. Hence, it can be concluded that the Petlyuk arrangement model is a better alternative to be implemented in the NGL fractionation train.

“…The studies where performance and environmental effects of combined cycle power generation units, which are an energy conversion system and are used extensively all over the world, are determined by using thermodynamic approaches as a part of case studies that are criticized by taking into consideration the concept of sustainability in sectors where energy conversion systems are used extensively 3 . In addition, the criticisms that are discussed within the framework of the sustainability concept by using thermodynamic approaches in the literature are carried out in a very wide perspective, from desalination systems to integrated systems with renewable energy, from the pharmaceutical industry to the aviation industry 4‐7 …”

The performance parameters, environmental sensitivity, and sustainability of a turbofan engine used extensively in military aviation are examined to the last detail. Assessment parameters named as energy efficiency, specific fuel consumption (SFC) and thrust, fuel heating value ratio (FHVR), thermal limit ratio (TLR), enthalpy ratio (ER), engine thrust ratio (ETR), fuel cost rate (FCR), specific fuel cost rate (SFCR), exergy efficiency, exergy destruction ratio, exergy loss ratio (ExLR), waste exergy ratio (WExR), exergetic improvement potential (ExIP), relative exergetic improvement potential (RExIP), productivity lack ratio (PLR), fuel exergy waste ratio (FExWR), environmental effect factor (EEF), ecological effect factor (EcoEF), sustainable efficiency factor (SEF), and exergetic sustainability index (ESI) were used to analyze thermodynamically the engine. The most sustainable and environmentally friendly components are researched and the results are presented to the literature. Between the components, the combustion chamber (CC) has the highest EEF with 0.8627 and the highest EcoEF value with 1.8627. Comparing the engine components, the low‐pressure turbine (LPT) has the best SEF value with 67.83 and the best ESI value with 66.83. Conversely, the CC has the worst SEF value with 2.16 and the best ESI value with 1.16. Ultimately, environmental and sustainability results from the analysis are expected to help understand the link between turbofan engine selection for both commercial and military aircraft and green flight paths, and therefore, make the choice of turbofan engines environmentally benign and greener.

“…Exergy analysis of the system showed that the most exergy destruction occurred in the boiler chamber and the central heat exchanger. 4 They also studied different types of desalination systems and their governing equations, then modeled the energy consumption of the evaporation vacuum evaporation system with a brine tank and reported on the economic analysis results. [5][6][7][8][9][10][11][12][13] Ghaebi et al investigated the thermodynamic modeling (including energy and exergy analysis) and the exogeochemical study of a power and hydrogen generation system including an organic Rankine cycle and a proton exchange membrane electrolyzer driven by geothermal energy, with different operating fluids (R245fa, R114, R600, and R236fa) to compare their effects on the performance of the payment system and used EES software for this purpose.…”

In this research, the integrated carbon dioxide power cycle with the geothermal energy source to supply the required reverse osmosis desalination power for freshwater production is defined. The cycling power is consumed by the desalination system and sodium hypochlorite generator. Exergoeconomic analysis, and optimization are studied. Exergoeconomic analysis is shown that the desalination system, sodium hypochlorite generator, carbon dioxide turbine, and natural gas turbine have the highest rate for the sum of capital gain and exergy destruction cost. For the first case of optimization, the total cost rate is considered as the objective function. The optimal inlet discharge rate of sodium hypochlorite generator was 62% of the brine water outlet discharge rate of the desalination system. Plus, the total cost rate is reduced by 10% compared to the general case when 100% of brine water discharge rate of the desalination system enters into the sodium hypochlorite generator. The second case is multiobjective optimization to reduce costs and increase productivity.
