Diagnosis of site-specific fouling problems in heat exchanger tubes

维护无垢管道被认为是工厂环境中换热器和锅炉可靠和高效运行的关键因素。然而，与时间相关的有害物质在管道内表面的自然沉积会导致腐蚀和管道失效，增加能量损失和维护**成本。因此，需要对现场特定的结垢物质进行调查，以确定结垢机制**并提出缓解结垢的最佳操作参数。**为此，**艾伯塔大学(University Of A)一个新的尖端研究机构的首席研究员Hyo-Jick Choi博士与总部位于艾伯塔省的领先测试和检测服务提供商red Ltd**联手研究特定站点的结垢物质。这种协同**合作提供了独特的技术实力和卓越的基础设施能力-Choi博士在材料科学、化学、生物技术和化学工程方面拥有超过20**年的多学科专业知识；**IRE散热有限公司是研究工厂环境中结垢的先驱。因此，达到**该提案的目标并实现创新解决方案的可能性很高。这项研究的结果将**补充IED的核心产品组合的诊断/清洁能力，使IED能够**为工厂设施提供**诊断服务以及现有的检查服务。**崔博士和他的实验室将分析现场特定的结垢管道，以确定结垢机制并确定**定量/定性结垢模式。这项研究将由一名研究助理和一名**本科生利用阿尔伯塔大学和**国家纳米技术研究所(NINT)提供的世界级表征设施进行。IRED将为现场样品的收集和**处理提供实践培训。这项研究产生的额外能力将极大地促进**加拿大植物行业的卓越研究，为IED及其客户提供经济利益，**并开创先进污垢缓解诊断的新领域。

Maintaining fouling-free tubes is considered a critical factor for reliable and efficient operation of heat**exchangers and boilers in plant settings. However, time-dependent natural deposition of unwanted substances**on the interior surface of tubes leads to the corrosion and tube failure, increasing energy loss and maintenance**costs. Therefore, investigation of site-specific fouling substance is required to identify the fouling mechanisms**and to propose optimal operational parameters for mitigation of fouling.**To this end, Dr. Hyo-Jick Choi, principal investigator of a new state-of-the-art research facility at the**University of Alberta (U of A), and IRED Thermal Ltd, a leading provider of testing and inspection services**based in Alberta, have come together to investigate site-specific fouling substances. This synergistic**collaboration offers unique technical strength and excellent infrastructure capability- Dr. Choi has over 20**years of multidisciplinary expertise in materials science, chemistry, biotechnology, and chemical engineering;**IRED Thermal Ltd is a pioneer in investigating fouling in a plant setting. As a result, the probability of meeting**the objectives of this proposal and realizing an innovative solution is high. Findings of this research will**supplement IRED's core portfolio with diagnostic/cleaning capabilities, enabling IRED to provide the**diagnostic service to a plant facility along with existing inspection service.**Dr. Choi and his lab will analyze the site-specific fouled tubes to determine the fouling mechanism and identify**quantitative/qualitative fouling patterns. This research will be carried out by a research associate and an**undergraduate student, using world-class characterization facilities available at the University of Alberta and**National Institute for Nanotechnology (NINT). IRED will provide hands-on training for the collection and**handling of on-site samples. Added capabilities emanating from this research will substantially promote**research excellence in Canadian plant industries, providing economic benefits to the IRED and its customers,**and ushering in a new area of advanced fouling mitigation diagnostics.
