The industrial sector is very promising for the use of solar thermal technology, since it accounts for a large share of the total final energy consumption (e.g. 27 % in Germany in 2010) and it predominantly uses the consumed energy as thermal energy (74 % in Germany in 2010). In order to develop this area of application, it is necessary to understand which industrial sectors have the highest potential, which processes within these sectors are most suitable for the integration of solar heat as well as to quantify the possible contribution to the industrial heat demand. For this thesis, the industrial heat consumption in Germany is analyzed, which leads to the selection of the 11 most promising sectors within industry. These are Chemicals, Food and beverages, Motor vehicles, Paper, Fabricated metal, Machinery and equipment, Rubber and plastic, Electrical equipment, Textiles, Printing and Wood. The theoretical potential of solar heat for industrial processes below 300 °C in Germany adds up to 134 TWh per year, the technical potential (considering efficiency measures, limited roof area and a solar fraction) being 16 TWh per year or 3.4 % of the overall industrial heat demand.Solar thermal systems can achieve higher system yields in industrial applications compared to domestic ones. At the same time, systems can be more complex in industrial applications. In order to design and operate solar process heat systems efficiently and to exploit the large potential, possible faults of such systems and their impact have to be evaluated. In this thesis, an implemented solar process heat system is methodically analyzed based on measurements and simulations with a validated model. Several faults are identified and their influence, as well as the influence of a reduced load on the system yield is evaluated. The analysis shows that a reduced load is most influential. Further, the most important impact factors on the system performance are identified: the collector parameters (?0, a1) and load characteristics (mass flow, temperature). The design of solar process heat systems is in many cases very demanding, hence costly. This high effort is a major barrier for a further development of solar heat for industrial applications. The decision to install solar thermal systems is in most cases based on solar heat generation cost. Collector field and heat store size are the most important figures for the estimation of the overall cost of a solar thermal system. Therefore, a simple approach for dimensioning the collector field and heat store is developed in this thesis in order to enable manufacturers and planners on one hand and costumers on the other hand to make a decision in favor or against a solar process heat system. In addition to investment cost, the specific system yield, which is determined for selected process heat applications in this thesis, is necessary to calculate solar heat generation cost. Finally, indications on the necessary accuracy of the load profile are provided to help to reduce effort in the design phase.

Colloquium on„Integrated Best Available Wastewater Management in the Textile Sector“September 19, 2018at Max-Planck-Institut für Festkörperforschung Lecture Hall 2D5, Heisenbergstraße 1, 70569 Stuttgart-BüsnauScientific Head: Dr.-Ing. Harald Schönberger University of Stuttgart Institute for Sanitary Engineering, Water Quality and Solid Waste Management (ISWA)Apart from cotton cultivation and the production of dyestuffs and optical brighteners, textile finishing – also called textile wet processing – is one of the environmental hotspots. The dominating emission mass stream from textile finishing is wastewater as practically all inorganic and most of the organic (more than 90 %) chemical compounds are discharged with wastewater. Emissions to air, although not negligible, and with solid wastes are of significant lower relevance. In addition, in many parts of the globe, water availability and water scarcity respectively are of increasing concern triggering the need to avoid, reduce or recycle textile wastewater.Against this background the colloquium will contribute to the development of integrated best available wastewater management practices in the textile sector. This comprises the minimisation of water, energy and chemicals consumption by process optimisation (process- and production-integrated measures) and the careful selection of chemicals products. The latter means that the chemical products should be free of substances which are non-biodegradable or which are toxic or do have a negative impact on aquatic life.As textile wastewater pollution cannot be fully prevented at source, the colloquium also focusses on its advanced and effective treatment with special consideration of its recycling in case of limited water availability or scarcity.The programme covers the aforementioned aspects. Well-known speakers will present latest technologies and technical concepts to the audience from textile finishing industries, retailers and brands, techniques providers, textile associations and authorities from national, regional and local level, GIZ and representatives of the German Partnership for Sustainable Textiles.The colloquium is being organised by the “Forschungs- und Entwicklungsinstitut für Industrie- und Siedlungswasserwirtschaft sowie Abfallwirtschaft e.V. (FEI)” in cooperation with the Institute for Sanitary Engineering, Water Quality and Solid Waste Management (ISWA) of the University of Stuttgart and the Partnership for Sustainable Textiles.

Chemicals and Methods for Conservation and Rest...

Before the 1970s, most information concerning the conservation and restoration of paintings, wood, and archaeological artefacts were focused on the history of the artefacts, previous attempts of conservation, and the future use of these artefacts. The technical methods of how the restoration and conservation were made were dealt with only very briefly. Today, sophisticated methods of scientific analysis such as DNA are common place, and this encourages conservators and scientists to work together to work out the development of new methods for analysis and conservation of artefacts. This book focuses on the chemicals used for conservation and restoration of various artefacts in artwork and archaeology, as well as special applications of these materials. Also the methods used, both methods for cleaning, conservation and restoration, as well as methods for the analysis of the state of the respective artefacts. Topics include oil paintings, paper conservation, textiles and dyes for them, archaeological wood, fossils, stones, metals and metallic coins, and glasses, including church windows.

Handbook of Manufacturing Processes
138,90 CHF *
ggf. zzgl. Versand

Overview Unlike any other reference, Handbook of Manufacturing Processes is an in-depth compilation of the workings of more than 1500 different manufacturing processes in metalworking, chemicals, textiles, plastics, ceramics, electronics, wood and food industries; as well as how more than 600 important products, components, materials are made. Logically organized in two sections -- a process section and a products section -- it describes clearly and succinctly the operations performed in the worlds factories. Heavily illustrated, it is a comprehensive source of technical manufacturing information that manufacturing engineers and managers, process engineers, and anyone who has an interest in or needs to know about manufacturing operations and products will not easily find anywhere else.
