09153 Control of Metal Dusting Using Alloy Selection, Coatings and Inhibitors

This study reports the results of laboratory investigations in pressurized high-temperature carbon-rich environments simulating operations in syngas production and root cause failure analysis and laboratory analysis simulations in refinery platformer operations. The results rank a variety of stainless steels and Ni alloys.

Metal dusting is a common design and operating constraint on high-temperature hydrocarbon processing. This study reports the results of laboratory investigations in pressurized high-temperature carbon-rich environments simulating operations in syngas production and root cause failure analysis and laboratory analysis simulations in refinery platformer operations. The results rank a variety of stainless steels, Ni-Fe-Cr alloys UNS N08800, N06601, N06025, N06690 and N06693 with respect to metal dusting resistance. Some fundamental aspects of metal dusting are discussed based on diffusion calculations, metallography, electron microscopy, energy-dispersive x-ray and electron back-scattering diffraction studies.

Keywords: high temperature corrosion, metal dusting, nickel alloys, syngas, platformer, inhibitors
