0607292ClackThis project will investigate the development of a novel mercury emissions control process called a virtual sorbent bed (VSB). The study aims to elucidate fundamental mechanisms of particle-gas transfer in turbulent flows and develop a novel control system for mercury emissions from combustion gas streams using the VSB. The project integrates experimental and modeling methods to obtain new knowledge of gas-particle mass transfer in turbulent flows to use in designing an effective mercury removal process. Instead of improving the characteristics of the sorbent, this project seeks to increase the mass transfer of mercury from the bulk gas flow to the sorbent surface. If the project were successful, it could yield an economic alternative to mercury control without expensive retrofits. The PI and co-PI have the background and qualifications to conduct the research. The potential benefits of the proposed work are high because mercury emissions from coal-fired power plants are a significant source of mercury, and the electric power industry is facing major regulatory requirements to decrease mercury emissions. Costs of existing emission control technologies are high. The project will include research opportunities for students through a program at IIT called Engineering Collectives, which integrates research teams of 3-6 students (high school, undergraduate and graduate students) to explore a research topic.

0607292Clack 该项目将研究开发一种称为虚拟吸附剂床 (VSB) 的新型汞排放控制工艺。该研究旨在阐明湍流中颗粒气体传递的基本机制，并使用 VSB 开发一种新型燃烧气流汞排放控制系统。该项目整合了实验和建模方法，以获得湍流中气体颗粒传质的新知识，用于设计有效的除汞工艺。该项目不是改善吸附剂的特性，而是寻求增加汞从大量气流到吸附剂表面的传质。如果该项目成功，它将可以产生一种经济的汞控制替代方案，而无需进行昂贵的改造。 PI和co-PI具有开展研究的背景和资格。拟议工作的潜在效益很高，因为燃煤发电厂的汞排放是汞的重要来源，而且电力行业面临着减少汞排放的重大监管要求。现有排放控制技术的成本很高。该项目将通过 IIT 的一个名为 Engineering Collectives 的项目为学生提供研究机会，该项目整合了 3-6 名学生（高中生、本科生和研究生）的研究团队来探索研究课题。
