U.S.-Finland Cooperative Research: Sodium and Sulfur Volatilization, Capture, and Aerosol Processes in Combustionand Gasification

该奖项支持W.J.Frederick教授和他在俄勒冈州立大学的研究小组成员与来自芬兰的两组工程师在化学工程研究方面进行合作。他们合作研究的目的是为钠气溶胶的形成和沉积以及高钠和/或硫含量燃料的燃烧和气化中的硫挥发和捕获过程提供基本的实验数据和基本模型。他们的研究计划将三个研究小组的互补专业知识和实验能力联系在一起：1)俄勒冈州立大学化学工程系弗雷德里克博士的小组，拥有高硫/钠燃料的速率过程和燃烧方面的专业知识；2)芬兰图尔库阿博学院大学M·M·胡帕博士领导的燃烧化学小组，该小组提供燃烧化学方面的专门知识；由E.I.Kauppinen领导的位于埃斯波的芬兰技术研究中心的气溶胶技术小组，在气溶胶科学方面带来了特别强大的理论和实验能力。该项目正在研究的高钠和高硫燃料对美国和芬兰都具有工业重要性。这一点反映在两国煤和废浆废液的沸腾床和加压气化工艺的发展中。拟议的研究结果有望对高硫煤或废纸浆废液加压气化等新工艺的设计以及现有技术的优化有所帮助。

This award supports Professor W. J. Frederick and members of his research group at Oregon State University to collaborate in chemical engineering research with two groups of engineers from Finland. The objectives of their cooperative research are to provide basic experimental data and fundamental models for the processes involved in sodium aerosol formation and deposition and also sulfur volatilization and capture in the combustion and gasification of high sodium and/or sulfur content fuels. Their research plan links the complementary expertise and experimental capabilities of three research groups: 1) Dr. Frederick's group in the Chemical Engineering Department of Oregon State University, with expertise in rate processes and combustion of high sulfur/sodium fuels; 2) the Combustion Chemistry Group led by Dr. M. M. Hupa at the Abo Academy University, in Turku, Finland, which offers expertise in combustion chemistry; and 3) the Aerosol Technology Group of the Technical Research Center of Finland, in Espoo, led by E. I. Kauppinen, which brings particularly strong theoretical and experimental capabilities in aerosol science. The high sodium and sulfur content fuels being studied in this project are of industrial importance to both the U.S. and Finland. This is reflected in the development of fluidized bed and pressurized gasification processes for coal and spent pulping liquors in both countries. The results of the proposed research are expected to be useful in the design of new processes such as pressurized gasification of high-sulfur coals or spent pulping liquors as well as in the optimization of existing technologies.
