Several studies investigated the effect of piperazine (PZ) in a mixture with other amines; however, its capability has rarely been investigated as a stand-alone absorbent. In this study, CO₂ solubility equilibrium simulations are performed using the Aspen Plus (v7.3.2, AspenTech) simulation tool for the CO₂/H₂O and CO₂/H₂O/aqueous PZ component systems to predict the CO₂ absorption rate and absorption capacity of the solvent. CO₂ equilibrium partial pressures (up to120 kPa) were calculated using electrolyte non-random two liquid (ENRTL) model with a full explanation of crucial dissociation representing the complicated electrolyte system based on Henry’s Law. The ENRTL model was used to calculate the activity coefficients in the electrolyte system, while the dissociation and equilibrium constants were implemented as a function of temperature and or obtained from reference state free energy. Aspen Plus calculations from the ENRTL model showed excellent results having less than 4% deviation from the experimental results reported in the published literature. A selected range of 0.1–1.2 m PZ concentration and temperature between 298–343 K was used to estimate CO₂ loadings using the simulations from the validated model. Various concentrations of aqueous PZ were then compared to benchmark solvent, that is, pressurized water for CO₂ absorption loading. The observed result showed that CO₂ absorption at PZ concentration of 0.5 m was 120% higher than the pressurized water solvent at the same temperature and partial pressure conditions. Additionally, the efficiency of  CO₂ removal obtained by using PZ was also observed to be higher than pressurized water scrubbing. In short, the obtained encouraging results portrays that PZ may be used as model solvent for CO₂ absorption from biogas and to limit its effect toward global warming.</p>\u0000 </div>","PeriodicalId":14051,"journal":{"name":"International Journal of Energy Research","volume":"2025 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/er/6621330","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144206939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines a sample of 218 countries over the period from 1998 to 2022, employing a range of empirical methodologies to analyze the impact of MNCs’ business behavior on environmental sustainability. The empirical findings are that: (1) there are complex effects between OBM and ESD. On the one hand, OBM has a negative impact on ESD, and on the other hand, OBM can positively impact ESD by promoting sustainable energy transition. (2) The degree of country regulation, government stability (GVS), and carbon footprint management (CFM) emerge as crucial factors in mitigating the adverse effects of OBM on ESD. (3) The moment quartile regression (MM-QR) results indicate that OBM is statistically significant for ESD in the lower and middle quartiles. Additionally, CFM exhibits greater significance for countries with lower levels of OBM, while GVS assumes heightened importance in nations characterized by greater OBM. It is worth noting that national regulations that are too strict or too lax are not conducive to environmental sustainability.

Distribution systems’ extensive reach makes it easier to integrate different renewable energies, particularly solar power, across different voltage levels. While integrating solar photovoltaic (PV) cells into existing traditional distribution systems may seem straightforward, studies reveal that their unchecked proliferation can lead to increased electrical losses and greater disruptions in power quality. This study introduces a coordinated methodology of PV energy systems and capacitor bank (CB) devices in electrical distribution feeders. The presented coordinated integration offers a sustainable energy solution for mitigating system losses, facilitating voltage profile enhancement as an important power quality indicator for adequate customer operation. In this regard, practical concerns include variations in power loadings, the discrete nature of CBs, and actual power production from PV sources are taken into consideration. For handling the presented coordinated integration, this paper develops the electric eel foraging-based optimization (EEFO) for energy efficiency and power quality improvement as well as environmental sustainability. The designed EEFO has been evaluated on practical Egyptian and standard IEEE distribution systems, demonstrating its effectiveness in minimizing energy losses and improving power quality.

Events with high impact and low probability of occurrence are a type of events that can cause severe disruptions in power grids. Therefore, the power grid must be resilient in dealing with such events. In recent years, electricity network operators have tried to improve the conditions of using distribution networks by using methods called flexibility. This paper aims to use flexible methods, such as energy storage systems and demand response programs to increase resiliency, reduce costs, and level the power exchange curve with the sub-distribution substation. Therefore, first, the modeling of energy storage systems and demand response programs is presented in the energy management problem. Then, the mentioned models are integrated with the problem of the resilient operation of the two-way distribution network. Also, considering the parameters of active and reactive loads and active generation of wind and solar renewable energy resources, uncertainty is considered in the problem. The resilient operation model has been considered and rewritten again, considering the robust optimization method for modeling uncertainties. Finally, a resiliency index is provided to show the resiliency of a network in a relative manner. In the proposed model, the simulation is done on IEEE 33-bus network in four states and six cases. The states considered include grid operation without energy storage systems and demand response programs, operation with energy storage systems, operation with demand response programs, and operation with the simultaneous presence of energy storage systems and demand response programs. Also, in this paper, six cases include operation in normal conditions for comparison with other cases, operation in outage conditions of one-way and two-way busses connected to the sub-distribution substation, operations in disconnection of some local resources, and network lines have been investigated.
