However, the direct (incineration) or indirect (gasification) combustion of waste generates relatively high emissions of several air pollutants, with different levels of toxicity. In specific situations, the presence of a waste combustion plant may be incompatible with the presence of population nearby, especially in areas where the dispersion of air pollutants is lim-ited by the local morphology and/or by unfavourable meteorological conditions. In such contexts, an alternative option exists: the conversion of the syngas produced by waste gasification into commercial products or fuels. This alternative would guarantee a significant reduction of the impacts on the local air quality, and it is expected to increase the level of acceptability of the WtE sector by the population: the syngas would not be burned locally to generate energy, but it would be used to produce valuable products or replace traditional fuels with more sustainable alternatives. Thus, this paper aims at discuss-ing the potential local impacts of traditional WtE plants and the opportunities related to alternative WtE approaches that may increase the level of sustainability of this sector. This paper will make a specific reference to mountainous regions, where the atmospheric dispersion of air pollutants may be negatively affected by the local morphology. To better illustrate the potential issues involved, some case studies located in an Alpine valley of Italy will be presented and","PeriodicalId":52236,"journal":{"name":"International Journal of Energy Production and Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49268845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Energy flexibility is an essential part of the holistic solution toward this variable production. Buildings are the largest consumers of energy around the globe. However, they also have the ability to become energy flexible. This article investigates the potential energy flexibility of a building zone with typical thermal properties in compliance with the Dubai building code, located in Dubai, where the dominant energy load is cooling. The cooling load is provided through a convective air conditioning system, which is typi- cal in Dubai, and the control strategy is based on the zone air temperature setpoint. Modulating the zone air temperature can result in significant changes in the cooling load, thus providing a certain amount of energy flexibility through the building thermal mass, which can then be used to shift and reduce the peak demand. We evaluated the effect of three strategies on the thermal zone, utilizing two energy flexibility indicators, the available structural energy storage capacity ( C ADR ) and the storage efficiency ( η ADR ). It is found that on a typical day in July, the analyzed zone can reach up to 570 Wh/m 2 of flexibility and achieve up to 3 h of load shifting, depending on the strategy utilized. and quantification of the an The of strategies typical in July was evaluated.

Within the context of existing situation, the electric power industry, which is currently actively developing, is an important element of power infrastructure that requires a long-term and con- tinuous solution of the challenges the industry faces. These are the circumstances of the development of methodological tools and decision-making procedures based on multi-criteria analysis, since the tasks of developing energy systems in modern conditions represent the most typical class of tasks where the problem of taking into account multi-criteria and uncertainty is most acute. The purpose of the study is to develop methods for the formation and comparison of options for the development of electric power systems in conditions of uncertainty and multi-criteria. The use of fuzzy set reporting models and new decision-making procedures based on fuzzy relations are proposed to address the development challenges. When addressing them, a considerable room for applying multi-criteria analysis algorithms to various aspects of the problem of power systems development in the fuzzy information environment was demonstrated. The results of the study are presented in the form of an analysis of the rational con- centration of power plant capacities, which made it possible to identify the most effective way to reduce the plant’s installed capacity while increasing the role of environmental criteria.","PeriodicalId":52236,"journal":{"name":"International Journal of Energy Production and Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47453868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a photovoltaic (PV) material that is used to replace traditional building materials in some parts of external buildings, such as the roof, skylights, or facades. It is increasingly used in the construction of new buildings as a main or additional source of electrical power generation to make the buildings self-sufficient in energy supply and thus reducing the costs of materials in external cladding of buildings and constitute an aesthetic design from other. One of the advantages of integrated solar power units, unlike non-integrated systems, is that they are the most common, are an integral part of the design, and are generally a better and more aesthetic combination than other solar options. These advantages led to the rapid development of sus- tainable sectors of the PV industry. The past decade has opened the door to countless solar photovoltaic (BIPV) buildings and other construction revolutions. In both new projects and renovations, BIPV has proven to be an energy-saving technology for use in residential, commercial, and industrial buildings as well as healthy buildings, and the harmony between sustainable design and nanotechnology assures promising future prospects for the construction industry to achieve sustainable buildings for a better built environment.","PeriodicalId":52236,"journal":{"name":"International Journal of Energy Production and Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41418121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Droplet shearing and size reduction due to the pump highly affect the separation performance. This paper aims to present an experimental investigation on the shearing of oil droplets in an oil/water production fluid passing through a high rpm single-stage centrifugal pump (C-pump) and a lower rpm gear pump. A cross polarizer microscope has achieved sample analyses. The experiments have been carried out at various water/oil ratios, from 70/30 to 90/10, with two different temperatures of 50 o C and 80 o C. Further, the viscosities of the fluid sample from both pump outlets are correlated with the water cuts. The results are presented in a graphical format showing the droplet size distributions of different cases from the two tested pump types. There is a general trend of higher shear intensity and smaller mean oil droplets with the C-pump than the gear pump. Water cut and the temperature seem to have a small effect on the shearing of the droplets. Further, the viscosity correlation for the fluid collected from two pump outlets at different temperatures and water cuts shows a slight decrease in viscosity with the shear rate. However, it is highly affected by the water cut and temperature.","PeriodicalId":52236,"journal":{"name":"International Journal of Energy Production and Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42443942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
