India’s mainstream political discourse is yet to grant genuine space to environmental issues or sustainable development;their priority being economic development. This is despite noteworthy environmental conservation movements and civil society organizations committed to the cause of the environment. Although the country has an array of competent environmental regulations, the environmental sustainability of the development programmes remains the least addressed. The case is not different for the Kerala state, despite its high literacy and human development matching many developed countries. The “Kerala Development Model” has been highly praised for its high-level social development. The apparently well-informed population of the state also outscores most states regarding environmental identity. In this context, this paper explores the Athirappilly hydroelectric Project pursued by the Kerala State Electricity Board Limited and other interest groups. It appears that the contemporary socio-economic-political scenario is urging the state's highly literate and politicized public to a post-nature or post-truth society increasingly engrossed in a consumerist lifestyle at the cost of the unique environmental setup. The present study also highlights how the Kerala population, once dominated by socialistic/liberal ideologies with egalitarian values, has been riding the neoliberal development wave giving little importance to nature and long-term ecological security. © 2023 The Center for Political Ecology.

Inelastic Deformation in Methylammonium Lead Iodide Perovskite and Mitigation by Additives during Thermal Cycling ( vol 9 , pg 2101 , 2024)

Metal halide perovskite thin films are promising materials for next-generation photovoltaic applications, but the thermomechanical instabilities of these materials are critical barriers to device longevity. In this study, we measure the evolution of stresses in methylammonium lead iodide (MAPbI3) films thermally cycled from 25 to 105 °C using a multibeam optical stress sensor (MOSS) system. We demonstrate that these films undergo residual stress buildup due to inelastic deformation as well as a simple mitigation strategy by incorporating low concentrations of 5-aminovaleric acid hydrochloride (5-AVACl) as an additive. Adding 5-AVACl increases the tensile stresses measured at room temperature but beneficially decreases the biaxial modulus from 9.60 ± 0.44 GPa to 7.95 ± 0.55 GPa, resulting in greater accommodation of thermal stresses. The hysteresis loop is ∼63% smaller with the inclusion of 5-AVACl, and the stress relaxation at 50 °C decreases from 86.46 to 51.49 MPa. The larger stress relaxation in pristine MAPbI3is correlated with grain boundary opening after five cycles, while the inclusion of 5-AVACl mitigates this degradation. Our findings underscore the importance of studying the dynamic response of perovskite films during thermal cycling and lay the foundation for further exploration into the mechanisms governing the thermomechanical behavior of perovskite thin films.

Microbial fuel cells (MFCs) represent a cost-effective, compact, and environmentally sound solution for the generation of renewable energy, with considerable potential for addressing environmental remediation challenges. MFCs possess the capacity to convert chemical energy derived from waste materials into electrical energy, thereby offering a sustainable and responsible avenue for the degradation of pollutants. In recent years, biochar, a carbon-rich material, has garnered significant attention due to its versatile applications in environmental and energy-related fields. This review primarily focuses on the effective and economically viable utilization of biochar for pollutant removal within MFCs. The substantial surface area and porous structure of biochar greatly enhance its ability to adsorb and subsequently decompose a wide spectrum of contaminants, encompassing organic compounds, heavy metals, and nutrients. These MFC systems have the unique capability to concurrently sequester carbon while generating electricity from organic waste sources by employing biochar as an electrode material. This approach not only provides an efficient means to reduce greenhouse gas emissions but also aligns with the principles of establishing a circular economy (CE). Furthermore, this review explores the concept of the CE, highlighting the sustainable contributions of biochar when integrated into MFCs. It offers a comprehensive analysis of the environmental benefits associated with the incorporation of biochar in MFCs, with a specific emphasis on pollutant removal, its potential for carbon sequestration, and its role in advancing the CE framework. Ultimately, the insights derived from this article serve as a foundational stepping stone for future technological advancements, contributing to realizing a more environmentally conscious and sustainable future. © 2024 The Institution of chemical Engineers

Ethane integration project—a study for Egyptian NGLs plants and their economics

Journal of engineering and Applied science 2024年第1期71卷 169页

For Egypt, ethane is a vital chemical precursor, with the potential to significantly attract financial resources and drive economic growth. Enhancing its added value necessitates efficient recovery of ethane before it enters the national grid without processing. This research investigates the technical and economic feasibility of integrating natural gas liquids (NGLs) from three Egyptian NGLs plants—South Western Desert NGLs (SWD NGLs), North Western Desert NGLs (NWD NGLs), and East Mediterranean NGLs (EMD NGLs)—to improve ethane recovery from natural gas fields. The study focuses on revamping these NGLs plants using various NGLs recovery techniques, conducting a comprehensive comparison to identify the most effective methods for processing rich feed gas. Detailed design of the NGLs recovery processes was developed using HYSYS V.14 simulation software and supplementary calculation sheets. The design criteria encompass both technical and economic parameters to ensure a holistic approach in meeting project requirements. Results indicate a significant increase in ethane recovery: 16% for SWD NGLs, 10% for NWD NGLs (A, B, C), and 85% for EMD NGLs. This improvement will boost ethane feedstock for petrochemical companies from 2000 ton/day to 3500 ton/day, enabling increased polyethylene production. Economic analysis for the base case shows an expected internal rate of return (IRR) of 26%, a net present value (NPV) of USD 73 million, and a payback period of approximately 3 years. Sensitivity analysis on product prices, feed gas prices, and total capital investment confirms the project’s economic viability, with all cases showing feasibility (IRR ≥ 15%) except when product prices fall below USD 225/ton for propane, USD 215/ton for liquefied petroleum gas (LPG), and USD 25/bbl for condensate. This study highlights the potential for enhanced ethane recovery, offering substantial economic benefits and supporting the growth of Egypt’s petrochemical industry. © The Author(s) 202
