It will contribute to the sustainable development of society and recede the dependency on fossil fuels, too. The energy metrics investigation is important for energy system because it talks about the feasibility of the system. The methodology consists of getting fundamental equations from energy balance equations. All fundamental equations with relevant data are fed to the code developed in MATLAB followed by the computation of overall energy and exergy. All types of climatic situations have been considered for the analysis. Data required for the same are accessed from IMD, Pune, India. The energy payback period, energy production factor, and life cycle conversion efficiency for N-CPC-ETC-SSU have been calculated at eight number of collectors, 0.012 mass flow rate and 0.14 m water depth. Results of N-CPC-ETC-SSU have been compared with results of SSU included with ETCs. Concludingly, energy payback period is lower by 6.41%, energy production factor is higher by 6.25% and exergy-based life cycle conversion efficiency is higher by 96.39% for N-CPC-ETC-SSU than N-ETC-SSU.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"43 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141741990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low-grade waste heat-driven seawater desalination technologies may improve the water-energy nexus issues of desalination systems by different configurations. The data envelopment analysis is used to determine the best final decision to achieve a better comparison of different parameters. The optimal configuration of low-grade waste heat driven seawater desalination is studied using flue gas waste heat in heat recovery boilers of an industrial oil refinery. Nine different types of multistage flash and multi-effect distillation (MED) desalination plants have been considered. The results show that the multistage flash brine recirculation may produce more desalinated water while the multi-effect distillation with three stages (3-stage MED) has the best payback period. Using 3-stage MED with a production of approximately 19,630 kg/h of water from 5.3 MW exhaust gas is more suitable for this design. Thus, the proposed strategy guides us toward the best decisions to configure low-grade waste heat-driven desalination plants for better design considering rigorous simulations for the plants. Moreover, this framework enables us to consider different criteria of technical, economic, and environmental issues for optimal configuration.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"43 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141741991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drying behavior of various combinations was scrutinized, and the physicochemical attributes of the dried bitter gourd samples, including total phenolic content, total flavonoid content, total chlorophyll content, antioxidant capacity, ascorbic acid content, and color, were analyzed. Rehydration characteristics, such as rehydration ratio, coefficient of rehydration, percent water in the rehydrated sample, and hardness of the rehydrated sample, were also determined. The bitter gourd slices achieved a final moisture content of 6.84%–8.27% wb after drying from an initial range of 88%–90% wb, within a total elapsed time of 28–55 h. The solar drying cabinet utilizing skewers exhibited enhanced efficiency, featuring reduced drying time and superior product quality compared to the tray-equipped drying cabinet.

Addressing this global issue involves tackling its root causes and closely monitoring progress in energy transition efforts to formulate effective strategies. Understanding the complexities and opportunities of shifting toward low-carbon economies underscores the necessity for innovative sector-specific policies promoting sustainable energy practices and reducing air pollution. An insightful grasp of how energy transitions impact environmental sustainability is critical, highlighting sector-specific dynamics for informed policy and decision-making. This study employs a wavelet approach to explore the relationship between CO2 emissions and renewable energy consumption, analyzing both aggregate and sector-specific metrics. This time-varying analysis offers a view of how this relationship evolves over time, providing valuable insights into the effectiveness and outcomes of sustainable energy strategies. Drawing on a dataset spanning from January 1989 to March 2022 in the United States, the research identifies coherence and co-movements across different frequencies and time dimensions. Results underscore the need to tailor energy strategies to sector-specific dynamics, particularly noting that despite the growing adoption of renewable energies in industrial and transportation sectors, their impact on reducing CO2 emissions remains limited.

The photoelectrode is applied to split wastewater under different light conditions: darkness, white light, and monochromatic light. In the absence of light, the CrO3-Cr2O3/Ppy photoelectrode produces a photocurrent density (Jph) value of 0.54 mA cm−2, which significantly increases to 0.78 mA cm−2 under white light exposure. The Jph values range from 0.68 to 0.76 mA cm−2 at wavelengths between 730 and 340 nm, showcasing the photoelectrode's remarkable sensitivity. This sensitivity highlights the potential of the photoelectrode to efficiently capture light energy for applications in wastewater treatment and green hydrogen production.

This detection is accomplished through a simple potentiometric technique, employing a simple two-electrode cell setup. To further validate its performance, cyclic voltammetry is conducted using a three-electrode system, revealing a remarkable sensitivity of 7.2 × 10−5 A M−1 for Pb2+ ions. The nanocomposite sensor's selectivity is rigorously examined by subjecting it to testing in the presence of 0.01 M interfering ions. The results unequivocally demonstrate that the sensor remains unresponsive to these interfering ions, underscoring its remarkable selectivity for Pb2+ ions. Moreover, the sensor's behavior is evaluated under real-world conditions using natural samples, where, no indications of interference from other ions are observed. This is estimated by the absence of cyclic peaks in the voltammogram, indicating the sensor's unique ability to selectively detect Pb2+ ions without being perturbed by other ions that may be naturally occurring in the samples. These findings emphasize the nanocomposite sensor's potential for a wide array of applications in environmental monitoring and analytical chemistry.

For numerical analysis, STAR-CD/ESICE software was employed. Methyl Oleate (C19H36O2) was predicted as the surrogate biodiesel based on Gas Chromatography (GC) analysis and average mass calculation. Notably, the numerical analysis revealed a remarkable similarity in brake power between the experimental and computational investigations.

However, carbon monoxide (CO) emissions ranged from 57% to 65% lower than those observed in the experimental study, while nitrogen oxide (NOx) emissions exhibited a reduction of 63% to 84%.
