Available in PDF, EPUB and Kindle. Book excerpt: The technical and economic conditions for reducing the energy consumption cost-efficiently and there by releasing a surplus of biomass fuel in the pulp and paper industry are changing. For example, new environmental restrictions increase the need for closed water loops and other system modifications, which can lead to increased opportunities for energy savings. Closing the water loops can however require that new processes be developed to remove non-process elements, and those processes are likely to increase the energy consumption. There has also been a deregulation of the power market, which creates new incentives and opportunities for cogeneration of electric power in the pulp and paper industry. Finally, energy policy instruments such as CO2 taxes, CO2 trading and long-term agreements between government and industry are intended to increase the incentive for industry to invest in energy saving projects. As a result of these new conditions, the degree of energy efficiency is likely to become a more strategic issue in the future for pulp mill operations. In order to achieve optimal cost-competitive operation, there is a need for a systematic approach to the system consequences when making the above-mentioned changes, also taking into account external factors, such as cost of fuel, power, etc.. Given this background, the objective of this thesis has been to perform overall energy system analysis for several green field mills and scenarios. The emphasis has been on understanding how the energy saving potential changes under different circumstances in the mill, i.e. the amount of warm and hot water produced, type of digester, etc.. The results show that there is between 1.0 and 2.2 GJ/air-dried metric tonne (GJ/t) of excess heat available in the model mills evaluated. Depending on the mill configuration, different amounts of live steam saving can be achieved, varying between 12 and 21% of the total live steam demand.

Book excerpt: Integrated Biorefineries: Design, Analysis, and Optimization examines how to create a competitive edge in biorefinery innovation through integration into existing processes and infrastructure. Leading experts from around the world working in design, synthesis, and optimization of integrated biorefineries present the various aspects of this complex process, capturing the state of the art in the advancing bioeconomy. The book defines an integrated biorefinery as a processing facility that transforms biomass into value-added products—from biofuels and biochemicals to food and pharmaceuticals. The chapters cover biorefinery product and process design, supply chains, process analysis, feedstocks, technologies, and policy and environmental analysis. They focus on second-generation feedstocks, including forestry resources, energy crops, agricultural residues, oils, and various waste materials. With the growing interest in sustainability in general and in renewable resources in industrial facilities, biorefineries are likely to play increasingly significant roles and have greater economic, environmental, and societal impact. This book fills an information gap by presenting cutting-edge advances that can effectively guide engineers and decision makers in the synthesis, selection, design, analysis, and optimization of biorefineries.

Download or read book Simulation and Optimization of a Generic Kraft Pulp Mill written by Javier Barahona Vazquez and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Canadian pulp and paper industry is going through an economic crisis mainly due to a decrease of world demand and aggressive competition from emerging nations. In this context, the forest biorefinery which can be defined as the "full integration of the incoming biomass and other raw materials, including energy, for simultaneous production of fibres for paper products, chemicals and energy", is one of the solutions for pulp and paper mills to diversify their core business and regain competiveness while continuing to produce traditional wood, pulp and paper products. Forest Biorefinery is one of the research areas in École Polytechnique within the E2D2BF laboratory (Efficacité Energétique et Développement Durable de la Bioraffinerie Forestière. This research unit mainly focuses on invesigating the technical and economic feasibility of the biorefinery implementation into pulp and paper mills, developping processes simulations of biorefinery technologies, proposing new methodologies for energy optimization of the biorefinery units and pulp and paper processes. The study performed during this internship is part of a BioKrEn project (Biorefinery, Kraft and Energy) which involves several Canadian industrial partners,3 partner mills , 2 research laboratory FPInnovations and CanmetEnergy laboratory, leader in innovation of clean and renewable energetic solutions as well as several universities. The objective of this project is to develop and demonstrate a methodology and criteria to evaluate the feasibility of bioenergy proposals for Canadian Kraft pulp mills and, to propose optimized process designs that best integrate biorefining into existing mills. The first part of the BioKrEn project was to develop a reference Kraft mill simulation model using CADSIM Plus (a pulp and paper simulation software) platform. This reference Kraft mill representative of the current situation of Canadian Kraft mill in terms of capacity production, utilities consumption and equipment used will be used as a basis for biorefinery implementation. The objectives of this internship were first to complete and tune the simulation, to validate it and then to optimize it in terms of mass and energy using pinch methodology. This methodology is based on a combined energy and water analysis of the process in order to optimize water use and to limit the energy consumption in the process. The analysis of a subsystem of the process, the water network, is required before a complete data extraction for the further analysis is performed. This report contains all data, graphs, tables and results of this study. It also reflects the approach that will be followed with some observations, remarks, difficulties and benefits that this work has generated. Resulting projects will be submitted to the partners in order to show a real average Canadian Energy consumption. Conclusions and future work are given at the end of the report.
