Abstract:As the urgency of current energy-saving and discharge reduction task and difficult of related advance technology in breaking through, a new energy flow network system model was built based on modelling elements and rules of hybrid Petri nets to adapt to the system requirements through analyzing the basis features of energy flow network, and meet the demand of developing energy flow network efficiency of iron and steel enterprises. The dynamic rules and behaviour mechanism of energy flow network system for iron and steel enterprises were studied by utilizing the model combined with the historical data, the results show that the modelling method is effective and satisfactory, and provide guidance for optimizing the energy system and exploring the relation of material flow and energy flow. IntroductionScholars and entrepreneurs at home and abroad have done a great deal of work on energy saving of iron and steel enterprises. Through the continuous development of theoretical and practical research work, academician Lu takes the system of iron and steel as the research object, and set up the theory of energy saving of industrial system by putting forward to a series of concepts and methods (Lu, 1996;2000). On account of complex characteristics of the material flow and energy flow in production process of the iron and steel, Lu put forward the concept models of standard materials flows diagram, standard energy consumption per ton and standard metal yield per ton, and establish the basic method for analyzing the impact the change of material flow on the energy consumption of each stock in the steel production process (Lu, 2000). Professor Cai built the energy saving decision making model of iron and steel enterprises by using the large system optimization method, and realized the optimization of the production system of Anshan Iron and Steel Group and get a more reasonable production plan (Cai,2012).The nature of production process is the flow process of material flow driven by energy flow in iron and steel enterprises, Academician Yin studied the essence and law of iron and steel production process from microcosmic to macroscopic aspects, and provided a method and breakthrough point for energy saving and consumption reduction of iron and steel system (Yin,1997;2000). Many foreign scholars have analyzed the energy consumption problem of industry or enterprise by applying the exergy analysis method of the second law of thermodynamics (Larsson, 2006;Polenske, 2002;Andersen, 2014). In the light of the specific case, the practical implementation scheme was put forward to achieve a certain optimization effect. The above modeling method either cannot optimize the whole energy system by taking a specific equipment and specific process of steel enterprise as the research object, or cannot effectively reflect the characteristics of the dynamic and orderly and compact system of the actual energy system in iron and steel enterprises by taking the production system as the object and maximizing the energy saving of the syst...

“…Many studies have focused on material and energy flows in the chemical (Worrell et al, 2000), petroleum (Ozalp and Hyman, 2007;Wang et al, 2004), metal (Andersen and Hyman, 2001;Michaelis and Jackson, 2000), and paper manufacturing industry (Hong et al, 2011); they have mainly focused on increasing the energy and material efficiency in these industries, and only a few scholars have been concerned with the cement/concrete industry. Low (2005) performed the first comprehensive material flow analysis for concrete, and calculated the amounts of raw material, water, and energy required as input, as well as the amounts of cement, emissions, cement clinker dust, and water required as output in US cement production.…”

a b s t r a c tCement production, which is highly dependent on the availability of natural resources, will face severe resource constraints in the future. This is especially true for the cement industry in China. Thus, the industry is focusing on reducing the consumption of natural resources at both the manufacturing and operational stages. The aim of this article is to improve the management of resources used in the cement production process and mitigate their environmental effects. First, material flow routes for the cement manufacturing process are established, after which three mass balances are built during the three production stages using actual plant data received from an existing cement manufacturing facility. Finally, the material efficiency of the units and stages as well as the waste recycle rates during these stages is calculated. The results show that approximately 2.48 t, 4.69 t, and 3.41 t of materials are required to produce a ton of the product in raw material preparation, clinker production, and cement grinding stages, and their waste rates are 63.31%, 74.12%, and 78.89%, respectively. The recycling rate of wastes during clinker production is remarkably higher than those during other manufacturing stages, wherein waste gases are directly discharged into the atmosphere. The material efficiency values for a raw mill, pyro-processing tower, rotary kiln, clink cooler, and cement mill are determined to be 36.69%, 34.24%, 39.24%, 29.76%, and 25.88%, respectively, whereas the waste recycling rates for these units are found to be 16.33%, 81.98%, 100.00%, 99.53%, and 0.00% respectively. These results will provide researchers with knowledge regarding the effectiveness and efficient use of natural resources in the cement sector. These important findings can also be used to influence the development of national and industrial policies in relation to the goal of achieving sustainable development in the cement industry.Crown

“…Only by comprehensively considering the coupling and separation effect between energy and material to research the energy transfer process can the integration and coordination of energy flow and material flow be properly understood and realized. Other researchers have investigated the mass and energy flow models for steel plant based on historical data, and analyzed the influences of enterprise energy structures in different technological processes, for example in [15,16]. Here, the researchers analyzed the energy consumption using static matching approaches; however such approaches cannot reflect the dynamic changes of energy.…”

Conventional historical data based material and energy balance analyses are static and isolated computations. Such methods cannot embody the cross-coupling effect of energy flow, material flow and information flow in the process industry; furthermore, they cannot easily realize the effective evaluation and comparison of different energy transfer processes by alternating the model module. In this paper, a novel method for material balance and energy conservation analysis of process industry energy transfer system is developed based on model property. Firstly, a reconfigurable energy transfer process model, which is independent of energy types and energy-consuming equipment, is presented from the viewpoint of the cross-coupling effect of energy flow, material flow and information flow. Thereafter the material balance determination is proposed based on both a dynamic incidence matrix and dynamic balance quantity. Moreover, the model-weighted conservation determination theorem is proved, and the energy efficiency analysis method is also discussed. Results confirmed the efficacy of the proposed methods, confirming its potential for use by process industry in energy efficiency analyses. OPEN ACCESSEnergies 2015, 8 12284
