The Editor’s Choice article from the June issue of CJCE is an open access review article by Pradeep Sambyal, Parisa Najmi, Devansh Sharma, Ehsan Khoshbakhti, Hadi Hosseini, Abbas S. Milani, and Mohammad Arjmand from University of British Columbia: “Plastic recycling: Challenges and opportunities”. Within this review, the authors provide “an in-depth exploration of current strategies for recycling plastic waste, focusing on mechanical, chemical, and energy recovery methods.” The article “situates these strategies within the context of modern practices by examining ongoing research methodologies and specific case studies related to various types of plastic waste” and discusses “the global crisis of plastic waste, along with various pre-treatment methods”. The authors note that the review “aims to provide a thorough overview and practical guidance on the recycling of plastic waste, offering essential insights for further development in this area.”
The second issue highlight is another open access article titled “Reaction kinetics of molybdenum dissolution by hydrogen peroxide in acidic and alkaline solutions using tartaric acid and sodium hydroxide: A semi-empirical model with rotating disc method” by Mahmoud Motasim, Tevfik Agacayak, Yasin Ramazan Eker, Salih Aydogan, and Ahmed Abbaker of Konya Technical University, Turkey, and Necmettin Erbakan University, Turkey, as well as Omdurman Islamic University, Sudan. This article “explores a sustainable process for the dissolution of molybdenum, focusing on the reaction kinetics in H2O2, H2O2-NaOH, and H2O2-C4H6O6 solutions.” Within the study, “A rotating disc method was applied with the Levich’s equation” and “Semi-empirical models with activation energy were developed for the H2O2-NaOH and H2O2-C4H6O6 solutions.” Access this article for the results!
The next issue highlight is another review article, this time by authors Ece Aylı and Eyup Kocak from Cankaya University, Turkey: “A comprehensive review of cyclone separator technology”. This review “examines the working principles, optimal dimensions, effects of key parameters, and the results of experimental/numerical studies on cyclone separators.” The study investigates “the effects of parameters such as vortex finder diameter, conical part diameter, cyclone separator diameter, cylinder height, inlet height, inlet width, vortex finder length, and cyclone total length on efficiency, performance, and pressure drop.” In addition, “the article explores current modifications and efforts to improve efficiency.” While the article could be used as a “guide to optimize the design and performance of cyclone separators”, it also “emphasizes new and innovative approaches to enhance their industrial applicability.”
The final issue highlight is an open access mini review article from authors Abderraouf Arabi, Ronaldo Luis Höhn, Jordi Pallares, and Youssef Stiriba from Universitat Rovira i Virgili, Spain: “Practical aspects of multiphase slug frequency: An overview”. In this article, the authors “discuss practical aspects of slug frequency for industrial purposes from an examination of published literature and available experimental data” and the review “shows that slug frequency appears to play a key role in the modelling of intermittent flow using 1-D mechanistic slug models and 3-D computational fluid dynamics tools” asd well as “the importance of slug frequency not only for petroleum engineering but also for chemical, nuclear, and mechanical engineering.”
