Description

Applications such as power generation, chemical processing, fuel cells, and high temperature heat exchangers are exposed to a high temperature aggressive gaseous environments which limit the life expectancy. Coking is the process of carbon deposition from a gas phase that is encountered in many petrochemical and other high temperature processes that can result in corrosion attack of the metals used in those applications. Ferritic and austenitic steels are common materials used in these applications. This research will explore the performance of ferritic and austenitic stainless steels in a high temperature coking atmosphere simulated in a laboratory tube furnace. The materials are analyzed using x-ray diffraction (XRD) and scanning electron microscopy (SEM) in order to compare the effect of carbon deposition, metal dusting, and development of high temperature oxide scale of both materials. This research can help develop strategies to improve the longevity of these materials when subject to these aggressive environments.
