The imperious necessity of reducing resource consumption and decreasing waste generation has led to reincorporating materials at the end-of-life (EoL) stage into the productive chain. Nonetheless, the presence of hazardous substances in the EoL stage materials poses a significant challenge for the transition toward the production model. The adequate transformation of these materials into feedstocks requires their correct allocation into recovery plants and final destinations. Such an allocation can be decided by resorting to optimisation by generating the best alternative networks, from where the stakeholders may decide the most suitable recycling scheme. In this work, a graph-theoretic approach is introduced to identify the best alternatives to reincorporate industrial EoL chemicals into the productive chain. This contribution presents the initial approach to this problem, demonstrated through a case study considering the data reported on the public-access release inventory data for n-hexane. Different recycling routes are proposed for the case study by optimising the total treatment cost, and their advantages and disadvantages are discussed; moreover, their efficiency concerning the circular economy is measured by comparing the amount of recovered chemicals. By generating plausible recycling alternatives, this work contributes positively to analysing potential alternatives for circular economy and resource conservation in industry.}, year = {2023}, eissn = {2283-9216}, pages = {349-354}, orcid-numbers = {Pimentel, Jean/0000-0003-3359-4848} } @article{MTMT:34140047, title = {Retrofit heat exchanger network optimization via graph-theoretical approach: Pinch-bounded N-best solutions allows positional swapping}, url = {https://m2.mtmt.hu/api/publication/34140047}, author = {Teng, Sin Yong and Orosz, Ákos and How, Bing Shen and Jansen, Jeroen J. and Friedler, Ferenc}, doi = {10.1016/j.energy.2023.129029}, journal-iso = {ENERGY}, journal = {ENERGY}, volume = {2023}, unique-id = {34140047}, issn = {0360-5442}, year = {2023}, eissn = {1873-6785}, pages = {129029}, orcid-numbers = {Teng, Sin Yong/0000-0002-2988-8053} } @article{MTMT:34126562, title = {Energy Efficient Drive Management of Lightweight Urban Vehicle}, url = {https://m2.mtmt.hu/api/publication/34126562}, author = {Pusztai, Zoltán and Szauter, Ferenc and Friedler, Ferenc}, doi = {10.3303/CET23103043}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {103}, unique-id = {34126562}, issn = {1974-9791}, year = {2023}, eissn = {2283-9216}, pages = {253-258} } @article{MTMT:34064369, title = {Optimization of vertical farms energy efficiency via multiperiodic graph-theoretical approach}, url = {https://m2.mtmt.hu/api/publication/34064369}, author = {Pimentel, Jean and Balázs, László and Friedler, Ferenc}, doi = {10.1016/j.jclepro.2023.137938}, journal-iso = {J CLEAN PROD}, journal = {JOURNAL OF CLEANER PRODUCTION}, volume = {416}, unique-id = {34064369}, issn = {0959-6526}, year = {2023}, eissn = {1879-1786}, orcid-numbers = {Pimentel, Jean/0000-0003-3359-4848; Balázs, László/0000-0001-7319-9389} } @article{MTMT:34018990, title = {Kriging-Assisted Multi-Objective Optimization Framework for Electric Motors Using Predetermined Driving Strategy}, url = {https://m2.mtmt.hu/api/publication/34018990}, author = {Istenes, György and Pusztai, Zoltán and Kőrös, Péter and Horváth, Zoltán and Friedler, Ferenc}, doi = {10.3390/en16124713}, journal-iso = {ENERGIES}, journal = {ENERGIES}, volume = {16}, unique-id = {34018990}, issn = {1996-1073}, abstract = {In this paper, a multi-objective optimization framework for electric motors and its validation is presented. This framework is suitable for the optimization of design variables of electric motors based on a predetermined driving strategy using MATLAB R2019b and Ansys Maxwell 2019 R3 software. The framework is capable of managing a wide range of objective functions due to its modular structure. The optimization can also be easily parallelized and enhanced with surrogate models to reduce the runtime. The framework is validated by manufacturing and measuring the optimized electric motor. The method’s applicability for solving electric motor design problems is demonstrated via the validation process. A test application is also presented, in which the operating points of a predetermined driving strategy provide the input for the optimization. The kriging surrogate model is used in the framework to reduce the runtime. The results of the optimization and the framework’s benefits and drawbacks are discussed through the provided examples, in addition to displaying the properly applicable design processes. The optimization framework provides a ready-to-use tool for optimizing electric motors based on the driving strategy for single- or multi-objective purposes. The applicability of the framework is demonstrated by optimizing the electric motor of a world recorder energy-efficient race vehicle. In this application, the optimization framework achieved a 2% improvement in energy consumption and a 9% increase in speed at a rated DC voltage, allowing the motor to operate at desired working points even with low battery voltage.}, year = {2023}, eissn = {1996-1073} } @article{MTMT:34009769, title = {Process synthesis considering sustainability for both normal and non-normal operations: P-graph approach}, url = {https://m2.mtmt.hu/api/publication/34009769}, author = {Orosz, Ákos and Varbanov, Petar and Klemeš, Jiri Jaromir and Friedler, Ferenc}, doi = {10.1016/j.jclepro.2023.137696}, journal-iso = {J CLEAN PROD}, journal = {JOURNAL OF CLEANER PRODUCTION}, volume = {414}, unique-id = {34009769}, issn = {0959-6526}, year = {2023}, eissn = {1879-1786} } @article{MTMT:33870068, title = {Synthesis of multiperiod heat exchanger networks: n-best networks with variable approach temperature}, url = {https://m2.mtmt.hu/api/publication/33870068}, author = {Piglerné, Lakner Rozália and Orosz, Ákos and How, Bing Shen and Friedler, Ferenc}, doi = {10.1016/j.tsep.2023.101912}, journal-iso = {TSEP}, journal = {THERMAL SCIENCE AND ENGINEERING PROGRESS}, volume = {42}, unique-id = {33870068}, issn = {2451-9049}, year = {2023}, eissn = {2451-9049}, orcid-numbers = {Piglerné, Lakner Rozália/0000-0001-5665-479X} } @article{MTMT:33700166, title = {Implementation of Optimized Regenerative Braking in Energy Efficient Driving Strategies}, url = {https://m2.mtmt.hu/api/publication/33700166}, author = {Pusztai, Zoltán and Kőrös, Péter and Szauter, Ferenc and Friedler, Ferenc}, doi = {10.3390/en16062682}, journal-iso = {ENERGIES}, journal = {ENERGIES}, volume = {16}, unique-id = {33700166}, issn = {1996-1073}, abstract = {In this paper, determination of optimized regenerative braking-torque function and application in energy efficient driving strategies is presented.
