SGER: Foundry Industry - Pollution Prevention of Volatile Organic Compound (VOC) Emissions from Green Sand Molding Systems

这是一个高风险、高潜力的项目，旨在研究一种减少绿色砂型金属铸造中挥发性有机化合物（VOCs）排放的新方法。这种污染的预防将通过探索将绿砂模具中粘合剂的索过酮工艺与等离子体处理技术相结合时发生的化学反应来完成。在金属铸造工业中，当液态金属和模砂/粘合剂之间发生化学反应时，会出现一个主要问题。在筛砂过程中，收集和处理废砂和空气中的颗粒构成了主要的废物流费用。这一拟议的工艺旨在回收大部分废砂进行再利用，并通过综合工艺控制显著减少挥发性有机化合物。这解决了目前由美国铸造协会、铸造金属联盟等在能源部赞助下正在建设的金属铸造路线图中确定的脱碳问题。重要的是，这也是一个GOALI项目，一个工业合作伙伴来到学术校园合作进行实验工作。

This pollution prevention would be accomplished by exploring the chemical reactions that take place when the sonoperoxone process for the binders in green sand molds is integrated with plasma processing techniques. In the metal casting industry, a major problem arises when chemical reactions take place between the liquid metal and the mold sand/binder. During shakeout, the collection and handling of the used sand and the airborne particulates constitutes a major waste-stream expense. This proposed process is aimed at reclaiming much of the waste sand for reuse, with significant reduction of the VOCs to be controlled by the integrated process. This addresses the decarbonization issues identified in the current Metal Casting Roadmap under construction by the American Foundrymens Society, the Cast Metals Coalition, et al under the sponsorship of the Department of Energy. It is significant that it is a GOALI project as well, with an industrial collaborator coming to the academic campus to collaborate in the experimental work.
