Estimating the Industrial Waste Heat recovery potential based on CO_2 emissions in the European non-metallic mineral industry
Energy Efficiency, 2018Co-Authors: Laia Miro, Tobias Jager, Russell Mckenna, Luisa F. CabezaAbstract:Industrial Waste Heat (IWH) is a key strategy to improve energy efficiency and reduce CO_2 emissions in the industry. But its potential for different countries remains unclear due to a non-existent or inconsistent data basis. The objective of this paper is to assess the IWH potential of the European non-metallic mineral industry, using databases which comprise CO_2 emissions of more than 400 Industrial sites as well as country- and sector-specific parameters. This sector is selected because of its homogenous nature, meaning that most sites carry out similar or the same processes, which facilitates site-level modelling with subsector-level assumptions. The bottom-up approach is employed to derive the IWH potential for this industry over the period 2007–2012. Average results in this period show an IWH potential per site of 0.33 PJ/a and a potential for the whole sector of 134 PJ/a. The countries with the largest IWH potentials are Germany, Italy, France and Spain with yearly average potentials of 23, 19, 17 and 16 PJ, respectively. The subsector with the most IWH potential is cement. Further work should focus on the improvement of methodologies to assess the IWH potential, in particular through a techno-economic assessment of links between IWH sources and potential sinks.

Thermal energy storage (TES) for Industrial Waste Heat (IWH) recovery: A review
Applied Energy, 2016Co-Authors: Laia Miro, Jaume Gasia, Luisa F. CabezaAbstract:Industrial activities have a huge potential for Waste Heat recovery. In spite of its high potential, Industrial Waste Heat (IWH) is currently underutilized. This may be due, on one hand, to the technical and economic difficulties in applying conventional Heat recovery methods and, on the other, the temporary or geographical mismatch between the energy released and its Heat demand. Thermal energy storage (TES) is a technology which can solve the existing mismatch by recovering the IWH and storing it for a later use. Moreover, the use of recovered IWH leads to a decrease of CO2emissions and to economic and energy savings. Depending on the distance between the IWH source and the Heat demand, TES systems can be placed on-site or the IWH can be transported by means of mobile TES systems, to an off-site Heat demand. Around 50 industry case studies, in which both on-site and off-site recovery systems are considered are here reviewed and discussed taking into account the characteristics of the Heat source, the Heat, the TES system, and the economic, environmental and energy savings. Besides, the trends and the maturity of the cases reviewed have been considered. On-site TES systems in the basic metals manufacturing are the technology and Industrial sector which has focused the most attention among the researchers, respectively. Moreover, water (or steam), erythritol and zeolite are the TES materials used in most industries and space comfort and electricity generation are the most recurrent applications.

Methodologies to estimate Industrial Waste Heat potential by transferring key figures: A case study for Spain
Applied Energy, 2016Co-Authors: Laia Miro, Sarah Brueckner, Russell Mckenna, Luisa F. CabezaAbstract:In the current European energy context, the use of recovered Industrial Waste Heat provides an attractive opportunity to substitute primary energy consumption by a low-emission and low-cost energy carrier. In the case of Industrial Waste Heat, this potential is currently not only largely untapped, but also unaccounted for. In order to achieve a widespread use of recovered Industrial Waste Heat, assessments with a large scope and high spatial resolution are needed. Three methods published in the period 2002–2010 have been found in the literature, which are potentially transferable to other regions. These three methods are based on either the energy consumption of each manufacturing sector or the individual site CO2 emissions. The scope of this analysis is, first, to investigate in how far a transfer of the figures to different countries or regions is sensible in comparison to former studies in the literature. In the process, some uncertainties when transferring methods were identified (different definitions of industry, different standard Industrial activities classifications or no standard at all, etc.). The second goal is, once the methodology is accepted, to apply it to a case study, in this case the Industrial sector in Spain and two of its counties (Catalonia and the Basque Country) for the years 2001, 2009, 2010 and 2013. In this period, and based on the different approaches employed, the Spanish annual Industrial Waste Heat potential ranges from 54.3 to 151.1 PJ, Catalonia from 8.6 to 29.7 PJ, and from 7.2 to 11.9 PJ for the Basque Country. The methods are considered highly transferable but uncertainties inevitably arise in the case that the source and destination Industrial sectors are very different.

mapping and discussing Industrial Waste Heat iwh potentials for different countries
Renewable & Sustainable Energy Reviews, 2015Co-Authors: Laia Miro, Sarah Bruckner, Luisa F. CabezaAbstract:In accordance to the current worldwide trend of reducing CO2 emissions and to make the industry more competitive incrementing its efficiency, some countries are starting to quantify their quantity of Industrial Waste Heat. In fact, to be able to recover and reuse this Waste Heat from Industrial processes as a source for other processes or activities, the availability of reliable data of the Industrial Waste Heat potential found in a region is a key point. For that, after an exhaustive literature research, this article shows Industrial Waste Heat data from 33 countries and 6 subregions of different countries. Their feasibility is assessed in the discussion part as it is expected and shown in most of the cases that the amount of Industrial Waste Heat is proportional to some parameters regarding the country and its industry like: the Energy Consumed by the Country, the Energy Consumed by the Industry and the amount of Industrial Waste Heat Intensive Industry in the country. Country scale has been chosen and it is shown that at other scales these parameters are not always available. Nevertheless, some of the studied cases found show data not fitting into this pattern (approximately 1/6 of the data found). That can be explained taking into account that in most of the studies the methodology to account the quantity of Industrial Waste Heat is not explained. Factors like the reference year of the data, the boundaries of the analysis, the type of Waste Heat considered, etc. affect to the report of quantity of Industrial Waste Heat. Therefore, the authors provide a set of parameters and recommend checking these in order to confirm the reliability of data referring to Industrial Waste Heat quantities.

investigations on the thermal stability long term reliability of lino3 kcl expanded graphite composite as Industrial Waste Heat storage material and its corrosion properties with metals
Applied Energy, 2017Co-Authors: Zhaowen Huang, Zigeng Luo, Xuenong Gao, Xiaoming Fang, Yutang Fang, Zhengguo ZhangAbstract:The aim of this work was to investigate the properties of LiNO3/KCl-expanded graphite (EG) composite phase change material (PCM) concerning its long-term usage for Industrial Waste Heat storage. Studies on the thermal stability and long-term reliability of this composite PCM as well as its compatibility with metals that commonly used in industries were conducted. By means of thermogravimetric analyzer (TGA) and differential scanning calorimeter (DSC), the initial thermal decomposition temperature of the composite PCM was found to be 315°C, and less than 1% and around 4% changes in phase change temperature and phase change latent Heat, respectively, were obtained after repeated melting/solidification cycles. Gravimetric analysis of different metal specimens after enduring 500 thermal cycles in contact with the composite PCM revealed that stainless steel 304L and carbon steel C20 could be considered as more suitable containment materials than brass H68 for long-term use. The results of this work not only confirmed the great potential of LiNO3/KCl-EG composite PCM to be used as Industrial Waste Heat storage medium, but also could facilitate experimental and numerical researches on the LiNO3/KCl-EG composite PCM-assisted latent Heat storage systems in future.

Mapping potentials of low-grade Industrial Waste Heat in Northern China
Resources Conservation and Recycling, 2017Co-Authors: Ao Luo, Jianjun Xia, Hao Fang, Borong Lin, Yi JiangAbstract:Abstract Low-grade Industrial Waste Heat has drawn great attention in China. A new regulation concerning low-grade Industrial Waste Heat (IWH) use has been issued by the NDRC (National Development and Reform Commission) and the Ministry of Housing and Urban-Rural Development. Among the four major tasks mentioned, the most important is investigating IWH. However, there is little official data on the amount of Waste Heat in China. This paper presents a three-level method of IWH investigation. Meanwhile, the information needed at each level is summed up and Heating area in northern China is taken as a case. A series of means are adopted, such as official statistics analysis, literature investigation, field test and so on. Results reveal the drastic situation of energy Waste, and the great potential for energy conservation through the use of IWH. Approximately, 100 Mtce (2.93 EJ) potential of Waste Heat in industry can be recovered during Heating season in whole northern China with 3.04 billion m3 of water saving. Questionnaire inquiry covers 11 cities in Hebei, a typical Industrial province. The feasibility and benefit of Waste Heat to district Heating (DH) were verified in a case in Qianxi county. But usually Waste Heat doesn’t distribute according to residential Heat demand, as details are necessary when we regard it as potential Heat source in any level. Moreover, it is recommended that policy makers should attach importance to data statistics, technology evaluation and stimulating market mechanism for proposed aim on Waste Heat.

Method for integrating low-grade Industrial Waste Heat into district Heating network
Building Simulation, 2016Co-Authors: Jianjun Xia, Kan Zhu, Yi JiangAbstract:Low-grade Industrial Waste Heat could be a considerable potential energy source for district Heating, on the condition that the Heat from different Industrial Waste Heat sources is integrated properly. This study considers a method for integrating low-grade Industrial Waste Heat into a district Heating system and focuses on how to improve the outlet temperature of Heat-collecting water by optimizing the Heat exchange flow for process integration. The pinch analysis concept is considered, and a newly developed thermal theory called entransy analysis is introduced. By using entransy dissipation to describe the energy quality loss during the Heat integration, this study analyzes how Heat exchange flows influence the final outlet water temperature and attempts to provide an efficient method to optimize the Heat exchange flow. Finally, the effectiveness of the proposed methodology is demonstrated by testing it in a project involving the recovery of Waste Heat from a copper plant for district Heating.

Key issues and solutions in a district Heating system using low-grade Industrial Waste Heat
Energy, 2015Co-Authors: Hao Fang, Jianjun Xia, Yi JiangAbstract:Industrial Waste Heat is increasingly being recognized as an important source of Heat for DH (district Heating) systems in cold regions to fill shortfalls in Heating requirements, while consuming less fossil energy than with conventional Heating sources. Most existing cases of Industrial Waste Heat utilization for Heating merely focus on Heat recovery from a single Waste Heat source for Heating either in the factory in which the Heat is generated or other buildings in the vicinity. The purpose of this paper is to discuss the key issues related to a DH system using two or more kinds of low-grade Industrial Waste Heat, at a temperature between 20 °C and 90 °C, for users a long distance away from the Heat sources, including the collection and integration of multiple-grade Waste Heat sources, long-distance delivery of Waste Heat, and peak shaving of the system. Solutions to these three issues are proposed to increase the efficiency of the system and for further and better promotion of such a system: 1) "Tangency technology" is designed and applied to find the optimal method of collecting Heat from multiple Waste Heat sources. 2) Lowering the temperature of the return water on the primary side has been proven to be crucial to the collection and long-distance delivery of Industrial Waste Heat. 3) Systems integrating both Industrial Waste Heat and fossil-fuel Heat are depicted. Industrial Waste Heat always provides the base load for the DH system, while the fossil-fuel Heat acts as the peak shaver. Lastly, a case study undertaken in Chifeng in northern China demonstrates how these solutions act in a first-ever DH demonstration project using multiple sources of Waste Heat from a copper smelter. In all, 390,000 GJ of Waste Heat was recovered, 35,000 t of CO2emission was reduced, and over 150,000 t of water was saved.

an operation strategy for using a ground Heat exchanger system for Industrial Waste Heat storage and extraction
Building Simulation, 2014Co-Authors: Hao Fang, Jianjun Xia, Yi JiangAbstract:A ground Heat exchanger system is applied as a way to improve the Heat recovery ratio in a project using Industrial Waste Heat recovery for district Heating. In order to meet the requirements of Industrial processes, the outlet water temperature of the system should be strictly controlled within a range, but the Heat transfer power varies with the warming or cooling of the soil. An operation strategy named “block by block” is implemented and a corresponding model is established. In this strategy, the total area of the system is divided into several blocks. The water flows by a specific combination of blocks at any given time, ensuring the outlet water temperature is relatively stable. By simulation, it is concluded that the strategy is fit for the practice of Industrial Waste Heat storage and extraction.

Industrial Waste Heat utilization for low temperature district Heating
Energy Policy, 2013Co-Authors: Hao Fang, Yingbo Su, Yi JiangAbstract:Large quantities of low grade Waste Heat are discharged into the environment, mostly via water evaporation, during Industrial processes. Putting this Industrial Waste Heat to productive use can reduce fossil fuel usage as well as CO2 emissions and water dissipation. The purpose of this paper is to propose a holistic approach to the integrated and efficient utilization of low-grade Industrial Waste Heat. Recovering Industrial Waste Heat for use in district Heating (DH) can increase the efficiency of the Industrial sector and the DH system, in a cost-efficient way defined by the index of investment vs. carbon reduction (ICR). Furthermore, low temperature DH network greatly benefits the recovery rate of Industrial Waste Heat. Based on data analysis and in-situ investigations, this paper discusses the potential for the implementation of such an approach in northern China, where conventional Heat sources for DH are insufficient. The universal design approach to Industrial-Waste-Heat based DH is proposed. Through a demonstration project, this approach is introduced in detail. This study finds three advantages to this approach: (1) improvement of the thermal energy efficiency of Industrial factories; (2) more cost-efficient than the traditional Heating mode; and (3) CO2 and pollutant emission reduction as well as water conservation.
