Workshop: Electron Beam Technical Conference Focused on Science, Applications, and Design Considerations, Summer of 2017 at Fermi Lab, Illinois.

1635881 Bloetscher为了现代化和改善废水处理厂(现在称为资源回收厂)的基础设施，计划于2017年夏季在美国能源部(DOE)伊利诺伊州费米实验室举办为期2天的研讨会。本次研讨会以环境工程为重点，是美国能源部2015年6月24-26日在伊利诺伊州阿贡国家实验室举办的加速器能源与环境应用研讨会的成果，该研讨会探索了加速器技术的高影响力应用的研究和开发机会，以应对广泛的能源和环境挑战。这次拟议的研讨会将汇集75-100个主要利益攸关方，重点确定未来资源回收工厂基础设施创新的一个方面。将涵盖以下主题：1)了解电子束背后的科学，2)电子束技术的优先应用，3)总体研讨会的设计考虑，目的是征求对制定研究路线图的讨论，该路线图将向工程界描述技术，并为具体的、高影响的应用打开潜在变革性设计方法的大门。总结调查结果的总结会议将通过会议记录记录下来，主席和组委会将以开放获取的形式在网上公布。讲习班将通过解决环境部门的潜在障碍和机会，增进发展可能具有变革性的电子束技术广泛应用所需的科学知识。在高压场下加速电子的技术已经应用于工业过程中；然而，这项技术还没有在环境问题上得到应用，除了波兰的一个烟道气应用，现在由于加速器的问题，这项技术无法运行。从智力优势的角度来看，电子束技术有可能解决与污泥、空气污染和废水处理相关的许多环境质量和处理问题。由于不熟悉技术、缺乏设计经验或缺乏预期成本，评估这些好处的努力一直受到限制。因此，该研讨会将提供一项计划，允许学术界和工业界获取设计考虑因素、成本数据和过程建模结果的知识，以便向下一代工程毕业生和专业人员展示。电子束技术过去开发的一个最重要的方面是，当这一过程第一次被应用时，阻碍采用的最大因素是资本成本。目前，加速器成本已降至1980年的25%-30%左右。将1980年的成本与现在的成本进行比较，例如，1980年迈阿密-戴德弗吉尼亚州重点污水处理厂以179万美元的成本安装了75千瓦的电子束功率原型，今天，以200万美元的成本可以获得450千瓦的电子束功率，这是一个相当低的成本。与水环境与再利用基金会(WERF)合作，他们确定电子束工艺是解决废水污泥(生物固体)土地应用面临的许多问题的潜在解决方案，并可能作为废物厌氧消化的一种预处理，用于未来的能源中性和/或能源正向资源回收设施，这是本次研讨会宣传的一个关键方面。

1635881BloetscherTo modernize and improve the infrastructure of wastewater treatment plants, now referred to as resource recovery plants, a 2-day workshop is proposed to be held in Summer of 2017 at the Fermi Lab, Illinois of US Department of Energy (DOE). This workshop, focused on environmental engineering, is follow up to findings from a DOE Workshop on Energy and Environmental Applications of Accelerators held on June 24-26, 2015 at the Argonne National Laboratory, Illinois That workshop explored research and development opportunities for high-impact applications of accelerator technology to address energy and environmental challenges in a broad sense. This proposed workshop would bring together 75 - 100 key stakeholders and focus on identifying one aspect of infrastructure innovations for resource recovery plants of the future.The following topics will be covered; Track 1) understanding the science behind electron beams, Track 2) priority applications of electron beam technology, and, Track 3) design considerations, with the overall workshop, with the goal of soliciting discussion towards the development of a research roadmap that will describe the technology to the engineering community and open the door to potentially transformative design approaches for specific, high impact applications. A concluding session to summarize the findings will be captured via proceedings that the chair and organizing committee will publish on-line as open access. The workshop will advance knowledge in developing the science needed to bring potentially transformative electron beam technology into widespread practice by addressing the potential barriers and opportunities in the environmental sector. Techniques for accelerating electrons under a field of high-voltage has been applied in industrial processes; however, no applications of this technology have been implemented for environmental issues, except at one flue-gas application in Poland and now due to issues with the accelerators this is not operational. From an intellectual merit perspective, electron beam technology has the potential to address a number of environmental quality and treatment concerns related to sludge, air pollution, and wastewater treatment. Efforts to evaluate these benefits have been limited by the lack of familiarity with the technology, lack of design experience, or lack of anticipated costs. Therefore, this workshop will deliver a plan that will allow academics and industry to have access to knowledge of design considerations, cost data, and process modeling results to present to the next generation of engineering graduates and professionals. One of the most important aspects of past exploits of the electron beam technology, was that when this process was first applied the single biggest factor against adoption was capital cost. At present, accelerator costs have been reduced to about 25-30 % of what they were in 1980. Comparing 1980 costs to present day costs, as an example, in 1980 the Miami-Dade Virginia Key Wastewater Treatment plant installed a prototype electron beam at a cost of $1.79 million for 75 k-watts of beam power, today, it is possible to obtain 450 k-watts of beam power for $2 million, a considerably lower cost. A collaboration with the Water Environment & Reuse Foundation (WERF) where they have identified the electron beam process as a potential solution to many of the issues facing land application of wastewater sludge (biosolids), and, as a possible pretreatment for anaerobic digestion of waste for energy neutral and/or energy positive resource recovery facilities of the future is a critical aspect of the outreach of this workshop.
