项目摘要

In 2006, industrial energy use was 407 TWh and represented 19 % of total energy end use in the UK. Of this, more than 36% was consumed by the food, chemicals, paper and metals industries. Food and drinks processing accounted for 42 TWh, paper 9.4 TWh, chemicals 64 TWh and metals 34 TWh. The UK's Kyoto target is to reduce greenhouse gas emissions by 12.5% from 1990 levels within the commitment period of 2008-2012. The UK is on course to meet this target but is unlikely to meet the tougher self-imposed target to cut CO2 emissions by 20% from 1990 levels by 2010. This target has now been superseded by new targets in a draft Climate Change Bill (HM Government, 2007). The Bill proposes to impose an interim target of 26-32% reduction in CO2 emissions by 2020 alongside the 60% reduction by 2050. The Energy White Paper published in 2007 sets out a framework of measures to address these challenging targets and energy efficiency is one of them.. Energy efficiency is becoming increasingly important in the process industries due to the rapid rises in energy costs in the last few years and the volatility of energy prices. Energy costs may also represent a significant proportion of the overall production costs in various process sectors and energy efficiency can offer one of the best approaches to increasing profitability and reducing environmental impacts. Energy efficiency can be achieved in a number of ways including improving the efficiency of equipment and unit operations, heat recovery and process integration. Over the last 30 years considerable research and development effort has been devoted to these fields. The heat recovery potential from the four main process industries is 2.8 TWh from the food sector, 1.6 TWh from the chemicals sector, 0.7 TWh from the metals sector and 0.34 TWh from the paper and pulp industry sector. By far, the greatest potential is in the food and drinks and chemical processing sectors and this research proposal will concentrate mainly on these two sectors even though most of the results and outcomes will be generic.The project aims to investigate and develop methodologies for the optimum thermal energy recovery from process waste streams in the food and chemicals process industries to improve thermal performance and minimize greenhouse gas emissions from unit and process operations. It will involve a combination of research approaches, that will include: i) a comprehensive literature review on energy recovery technologies particularly those that can be applied to processes that involve organic materials and heat exchanger fouling; ii) development of a database and simplified knowledge based tools to facilitate the selection, by non experts, of the most appropriate technology for a particular application; iii) detailed field monitoring and investigations to obtain comprehensive data sets for process analysis and thermodynamic model validation; iv) thermodynamic model development for detailed system analysis, optimum thermal design, integration and control, and iv) generalization and dissemination of results. If heat recovery is widely employed in the process industries annual savings of 5.4 TWh can be achieved with additional 11 TWh savings being available from the wide application of open and closed cycle heat pumps to upgrade waste heat to more useful temperatures. If it is assumed that the displaced fuel will be gas then the wide application of heat recovery technologies, including heat pumps, has the potential of 3.0 MtCO2 emissions reduction per year and 462 M savings in fuel bills. Successful application of these technologies will also lead to increased employment and export opportunities for the UK manufacturing industry.

2006年，工业能源使用量为407 TWH，占英国总能源最终用途的19％。其中，食品，化学品，纸和金属行业消耗了超过36％的人。食品和饮料加工占42个TWH，纸9.4 TWH，化学物质64 TWH和金属34 TWH。英国的京都目标是在2008 - 2012年的承诺期内将温室气体排放量从1990年的水平减少12.5％。英国正在实现这一目标，但不太可能实现从1990年到2010年将CO2排放量减少20％的艰难的自我实现的目标。该目标现在已在气候变化法案草案中被新目标取代（HM Guardment，2007年）。该法案提议将到2020年二氧化碳排放量减少26-32％的临时目标以及到2050年的60％降低。2007年发表的能源白皮书制定了一个措施，以解决这些具有挑战性的目标和能源效率是其中之一。.能源效率在能源工业中越来越重要，因为在能源成本中，价格越来越多，几年的价格上涨了几年，并且在几年中的价格上涨了。能源成本也可能代表各个过程中总体生产成本的很大一部分，并且能源效率可以为提高盈利能力和降低环境影响提供最佳方法之一。可以通过多种方式来实现能源效率，包括提高设备和设备操作的效率，热量恢复和过程集成。在过去的30年中，大量的研发工作已专门用于这些领域。来自四个主要工艺行业的热回收潜力为2.8 TWH，来自化学品领域的1.6 TWH，金属行业的0.7 TWH，纸和纸浆行业领域的0.34 TWH。到目前为止，最大的潜力是在食品，饮料和化学处理部门中，该研究建议将主要集中于这两个领域，即使大多数结果和结果将是通用的。它将涉及研究方法的组合，其中包括：i）关于能源回收技术的全面文献综述，尤其是那些可以应用于涉及有机材料和热交换器结垢的过程的文献综述； ii）开发数据库和简化的基于知识的工具，以促进非专家的选择，该技术是特定应用程序最合适的技术； iii）详细的现场监控和研究，以获取用于过程分析和热力学模型验证的全面数据集； iv）热力学模型开发，用于详细的系统分析，最佳热设计，整合和控制以及iv）结果的概括和传播。如果在流程行业中广泛使用热恢复，则可以实现5.4 TWH的每年节省，而从开放和封闭的循环热泵的广泛应用中可以节省11个TWH，以将废热升级到更有用的温度。如果假定流离失所的燃料将是气体，那么包括热泵在内的广泛应用每年减少3.0 mtco2排放量，并在燃油费用中节省462 m。这些技术的成功应用还将导致英国制造业的就业和出口机会增加。
