The GCCA technique has been developed to complement the generic graphical Source and Demand Curves (SDC) in terms of the efficiency, accuracy and the ability to handle cases involving a large number of stationary emission sources. The GCCA technique is used with the Carbon Management Hierarchy (CMH) to systematically achieve the holistic minimum carbon targets through the application of all carbon minimisation options including direct reuse, source and demand manipulations, regeneration reuse, and carbon sequestration. Application of the GCCA tool on a refinery site can potentially result in the minimum fresh carbon target of 23.82 t/h, and zero carbon emission. This is a significant reduction from the base case fresh carbon demand of 289.30 t/h and carbon emission of 279.79 t/h. (C) 2014 Elsevier Ltd.

The method is based on a novel approach to the optimisation of renewable energy supply. A new algorithm for revealing energy supply chain clusters is introduced, described and illustrated by a case study. It has been developed on two levels. The first is a top-level supply chain network with lowest Carbon Footprint generated. It consists of a number of zone clusters. The definition of zones is provided; it can be e.g. a village or a town. Each zone is considered as a unit. At the second level is a supply chain synthesis carried out by P-graph based optimisation within each cluster. It provides a more detailed analysis. The use of the P-graph framework as a synthesis toolset provides a strong mathematically proven fundament for handling the complexity of the synthesis problem. It contributes to the optimal network design with a high computational efficiency. This approach contributes to the cleaner generation of energy from biomass, approaching CO2 neutrality as much as possible. It is beneficial for extending the use of biomass as a renewable source of energy. © 2010.}, keywords = {Optimization; BIOMASS; Supply chain management; Renewable energy source; Renewable energy sources; Clustering algorithms; Computational efficiency; Process graphs; P-graphs; Regional Energy Clustering Algorithm; Process graph (P-graph); Biomass supply chain synthesis; Carbon footprint; Supply chains; Carbon footprint minimisation; Biomass supply chain}, year = {2010}, eissn = {1873-4375}, pages = {782-792} } @article{MTMT:1268041, title = {P-graph methodology for cost-effective reduction of carbon emissions involving fuel cell combined cycles}, url = {https://m2.mtmt.hu/api/publication/1268041}, author = {Varbanov, Petar and Friedler, Ferenc}, doi = {10.1016/j.applthermaleng.2008.02.007}, journal-iso = {APPL THERM ENG}, journal = {APPLIED THERMAL ENGINEERING}, volume = {28}, unique-id = {1268041}, issn = {1359-4311}, abstract = {Fuel cells are under extensive investigation for building combined energy cycles due to the higher efficiency potential they offer. Two kinds of high-temperature fuel cells (HTFC) have been identified as best candidates for fuel cell combined cycles (FCCC) - molten carbonate fuel cells (MCFC) and solid oxide fuel cells (SOFC). The paper presents a procedure for the evaluation of energy conversion systems involving FCCC subsystems, utilising biomass and/or fossil fuels, providing a tool for evaluation of the trends in CO, emission levels and economics of such systems. This involves significant combinatorial complexity, efficiently handled by the P-graph algorithms. Promising system components are evaluated using the P-graph framework and a methodology for the synthesis of cost-optimal FCCC configurations is developed, accounting for the carbon footprint of the various technology and fuel options. The results show that such systems employing renewable fuels can be economically viable for a wide range of economic conditions, mainly due to the high energy efficiency of the FC-based systems.}, year = {2008}, eissn = {1873-5606}, pages = {2020-2029} } @article{MTMT:1044819, title = {Downstream process synthesis for biochemical production of butanol, ethanol, and acetone from grains: Generation of optimal and near-optimal flowsheets with conventional operating units}, url = {https://m2.mtmt.hu/api/publication/1044819}, author = {Liu, J and Fan, L T and Seib, P and Friedler, Ferenc and Bertók, Botond}, doi = {10.1021/bp049845v}, journal-iso = {BIOTECHNOL PROGR}, journal = {BIOTECHNOLOGY PROGRESS}, volume = {20}, unique-id = {1044819}, issn = {8756-7938}, year = {2004}, eissn = {1520-6033}, pages = {1518-1527}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @article{MTMT:1044829, title = {A graph-theoretic method to identify candidate mechanisms for deriving the rate law of a catalytic reaction}, url = {https://m2.mtmt.hu/api/publication/1044829}, author = {Fan, L T and Bertók, Botond and Friedler, Ferenc}, doi = {10.1016/S0097-8485(01)00119-X}, journal-iso = {COMPUT CHEM}, journal = {COMPUTERS & CHEMISTRY}, volume = {26}, unique-id = {1044829}, issn = {0097-8485}, year = {2002}, eissn = {1879-0763}, pages = {265-292}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @article{MTMT:1044831, title = {Integrated synthesis of process and heat exchanger networks: algorithmic approach}, url = {https://m2.mtmt.hu/api/publication/1044831}, author = {Nagy, A B and Adonyi, Róbert and Halász, László and Friedler, Ferenc and Fan, L T}, doi = {10.1016/S1359-4311(01)00033-3}, journal-iso = {APPL THERM ENG}, journal = {APPLIED THERMAL ENGINEERING}, volume = {21}, unique-id = {1044831}, issn = {1359-4311}, year = {2001}, eissn = {1873-5606}, pages = {1407-1427} } @article{MTMT:1044843, title = {Process network synthesis: Problem definition}, url = {https://m2.mtmt.hu/api/publication/1044843}, author = {Friedler, Ferenc and Fan, L T and Imreh, B}, doi = {10.1002/(SICI)1097-0037(199803)31:2<119::AID-NET6>3.0.CO;2-K}, journal-iso = {NETWORKS}, journal = {NETWORKS: AN INTERNATIONAL JOURNAL}, volume = {31}, unique-id = {1044843}, issn = {0028-3045}, year = {1998}, eissn = {1097-0037}, pages = {119-124} } @article{MTMT:1674726, title = {Targeting and design methodology for reduction of fuel, power and CO2 on total sites}, url = {https://m2.mtmt.hu/api/publication/1674726}, author = {Klemeš, Jiri Jaromir and Dhole, V R and Raissi, K and Perry, S J and Puigjaner, L}, journal-iso = {APPL THERM ENG}, journal = {APPLIED THERMAL ENGINEERING}, volume = {17}, unique-id = {1674726}, issn = {1359-4311}, abstract = {Simultaneous optimisation of production processes and total site utility systems provides a novel methodology that can reduce energy demands and emissions on a total factory site whilst simultaneously avoiding loss of cogeneration efficiency.

The novel methodology took into account the specific features of semi-continuous and batch operations and also the opportunities offered by the multi-objective optimisation of the design strategy for the total site. The environmental costs and potential for regulatory action were also incorporated. Software tools were developed to support the total site approach which was subsequently tested and its capabilities validated by successfully solving various case studies from different industrial sectors. © European Communities 1997.
